HOW TO USE THIS MANUAL

This manual was written by the Yamaha Motor Company primarily for use by Yamaha dealers and their qualified mechanics. It is not possible to put an entire mechanic's education into one manual, so it is assumed that persons using this book to perform maintenance and repairs on Yamaha snowmobiles have a basic understanding of the mechanical concepts and procedures inherent in snowmobile repair. Without such knowledge, attempted repairs or service to this model may render it unfit and/or unsafe to use. Yamaha Motor Company, Ltd. is continually striving to improve all models manufactured by Yamaha. Modifications and significant changes in specifications or procedures will be forwarded to all authorized Yamaha dealers and will, where applicable, appear in future editions of this manual.

Particularly important information is distinguished in this manual by the following notations:

~ The Safety Alert Symbol means ATTENTION! BE ALERT! YOUR SAFETY IS INVOLVED!

Failure to follow WARNING instructions could result in severe injury or death to the snowmobile operator, a bystander, or a person inspecting or repairing the snowmobile.

A CAUTION indicates special precautions that must be taken to avoid damage to the snowmobile. NOTE: A NOTE provides key information that can make procedures easier or clearer. MANUAL FORMAT All of the procedures in this manual are organized in a sequential, step-by-step format. The information has been compiled to provide the mechanic with an easy to read, handy reference that contains comprehensive explanations of all inspection, repair, assembly, and disassembly operations. In this revised format, the condition of a faulty component will precede an arrow symbol and the course of action required to correct the problem will follow the symbol, e.g., • Bearings Pitting/damage -+ Replace.

IMPORTANT INFORMATION

II~~~ I~I

IMPORTANT INFORMATION PREPARATION FOR REMOVAL AND DISASSEMBLY

1. Remove all dirt, mud, dust, and foreign material before removal and disassembly. While cleaning, take care to protect the electrical parts, such as relays, switches, motor, resistors, controllers, etc., from high pressure water splashes. SCH1030

2. Use proper tools and cleaning equipment. Refer to "SPECIAL TOOLS".

3. When disassembling the machine, keep mated parts together. This includes gears, cylinders, pistons, and other parts that have been "mated" through normal wear. Mated parts must be reused or replaced as an assembly.

4. During disassembly of the machine, clean all parts and place them in trays in the order of disassembly. This will speed up assembly time and help ensure that all parts are reinstalled correctly.

5. Keep all parts away from any source of fire.

6. Be sure to keep to the tightening torque specifications. When tightening bolts, nuts, and screws, start with those that have larger diameters, and proceed from the inside to the outside in a crisscross pattern.

ALL REPLACEMENT PARTS We recommend using genuine Yamaha parts for all replacements. Use oil and grease recommended by Yamaha for assembly and adjustments.

IMPORTANT INFORMATION

II~~~ I~I

GASKETS, OIL SEALS, AND O-RINGS 1. All gaskets, seals, and O-rings should be replaced when an engine is overhauled. All gasket surlaces, oil seal lips, and O-rings must be cleaned. 2. Properly oil all mating parts and bearings during reassembly. Apply grease to the oil seal lips.

LOCK WASHERS/PLATES AND COTTER PINS All lock washers/plates CD and cotter pins must be replaced if they are removed. Lock tab(s) should be bent along the bolt or nut flat(s) after the bolt or nut has been properly tightened.

BEARINGS AND OIL SEALS Install the bearings CD and oil seals ® with their manufacturer's marks or numbers facing outwards. (In other words, the stamped letters must be on the side exposed to view.) When installing oil seals, apply a light coating of lightweight lithium base grease to the seal lips. Oil the bearings liberally when installing.

Do not use compressed air to spin the bearings dry. This causes damage to the surface of the bearings.

SCH1120

CIRCLIPS All circlips should be inspected carefully before reassembly. Always replace piston pin clips after one use. Replace misshapen circlips. When installing a circlip CD, make sure that the sharp edged corner ® is positioned opposite to the thrust ® it receives. See the sectionalview.

MAXIMIZING DRIVE TRACK LIFE

IANOSJP I (O~ ~

I

----------------------------MAXIMIZING DRIVE TRACK LIFE I

Recommendations Track tension During initial break-in, the new drive track will tend to stretch quickly as the track settles. Be sure to correct the track tension and alignment frequently. (See pages 2-36 --- 2-37 for adjustment procedures.) A loose track can slip (ratchet), derail or catch on suspension parts causing severe damage. Do not overtighten the drive track, otherwise it may increase the friction between the track and the slide runners, resulting in the rapid wear of both components. Also, this may put an excessive load on the suspension components, resulting in component failure. Marginal snow The drive track and the slide runners are lubricated and cooled by snow and water. To prevent the drive track and slide runners from overheating, avoid sustained high-speed usage in areas such as icy trails, frozen lakes and rivers that have minimal snow coverage. An overheated track will be weakened internally, which may cause failure or damage. Off-trail riding Avoid off-trail riding until there is sufficient snow coverage. It generally takes several feet of snow to provide a good overall base to properly cover debris, such as rocks, logs, etc. If snow coverage is not sufficient, stay on trails to avoid impact damage to the drive track. Studded track In general, track life will be shortened when studs are installed. Drilling stud holes into the drive track will cut the internal fibers, which weakens the track. Avoid spinning the drive track. Studs may catch on an object and pull out of the track, leaving tears and damage around the already weakened area. To minimize possible damage, consult your stud manufacturer for installation and stud pattern recommendations. Yamaha does not recommend track studding.

BATTERY INSPECTION

ffmIJDIm1 ---------Batteries generate explosive hydrogen gas and contain electrolyte which is made of poisonous and highly caustic sulfuric acid. Therefore, always follow these preventive measures: • Wear protective eye gear when handling or working near batteries. • Charge batteries in a well-ventilated area. • Keep batteries away from fire, sparks or open flames (e.g., welding equipment, lighted cigarettes). • DO NOT SMOKE when charging or handling batteries. • KEEP BATTERIES AND ELECTROLYTE OUT OF REACH OF CHILDREN. • Avoid bodily contact with electrolyte as it can cause severe burns or permanent eye injury. First aid in case of bodily contact: External • SKIN - Wash with water. • EYES - Flush with water for 15 minutes and get immediate medical attention. Internal • Drink large quantities of water or milk followed with milk of magnesia, beaten egg or vegetable oil. Get immediate medical attention.

18350701

• This is a sealed battery. Never remove the sealing caps because the balance between cells will not be maintained and battery performance will deteriorate. • Charging time, charging amperage and charging voltage for a MF battery are different from those of conventional batteries. The MF battery should be charged as explained in the charging method illustrations. If the battery is overcharged, the electrolyte level will drop considerably. Therefore, take special care when charging the battery.

Since MF batteries are sealed, it is not possible to check the charge state of the battery by measuring the specific gravity of the electrolyte. Therefore, the charge of the battery has to be checked by measuring the voltage at the battery terminals. 1. Disconnect: • Battery leads (from the battery terminals)

First, disconnect the negative lead CD, then the positive lead ®. 2. Remove: • Battery 3. Inspect: • Battery charge

• Make sure that the battery vent is free of obstructions. • Never remove the MF battery sealing caps. • Do not use a high-rate battery charger. They force a high-amperage current into the battery quickly and can cause battery overheating and battery plate damage. ·If it is impossible to regulate the charging current on the battery charger, be careful not to overcharge the battery. • When charging a battery, be sure to remove it from the motorcycle. (If charging has to be done with the battery mounted on the motorcycle, disconnect the negative lead from the battery terminal.) • To reduce the chance of sparks, do not plug in the battery charger until the battery charger leads are connected to the battery. • Before removing the battery charger lead clips from the battery terminals, be sure to turn off the battery charger. • Make sure that the battery charger lead clips are in full contact with the battery terminal and that they are not shorted. A corroded battery charger lead clip may generate heat in the contact area and a weak clip spring may cause sparks. • If the battery becomes hot to the touch at any time during the charging process, disconnect the battery charger and let the battery cool before reconnecting it. Hot batteries can explode! • As shown in the following illustration, the open-circuit voltage of a MF battery stabilizes about 30 minutes after charging has been completed. Therefore, wait 30 minutes after charging is completed before measuring the open-circuit voltage.

CLUTCH/GEAR SELECTION

IANOSJP I (O~ ~

I

----------------------------The clutch may require tuning depending upon I

where the machine will be operated and the desired handling characteristics. The clutch can be tuned by changing the engagement and shifting speeds. Clutch engagement speed is defined as the engine speed at which the machine first begins to move from a complete stop. Clutch shifting speed is defined as the engine speed reached when the machine has travelled 800 m (2,500 ft) after being started at fullthrottle from a dead stop. Normally, when a machine reaches shifting speed, the vehicle speed increases but the engine speed remains nearly constant. Under unfavorable conditions (wet snow, icy snow, hills, or rough terrain), however, engine speed may decrease after the shifting speed has been reached.

GEAR SELECTION The reduction ratio of the driven gear to the drive gear must be set according to the snow conditions. If there are many rough surfaces or unfavorable snow conditions, the drive/driven gear ratio should be increased. If the surfaces are fairly smooth or better snow conditions exist, decrease the ratio. Gear ratio chart The drive and driven gears and the chains shown in the gear ratio chart are available as options. The figures containing a decimal point represent the drive/driven gear ratios, while the bottom numbers designate the number of links in the chain.

GENERAL TORQUE SPECIFICATIONSI DEFINITION OF UNITS

GENERAL TORQUE SPECIFICATIONS This chart specifies torque for standard fasteners with standard I.S.0. pitch threads. Torque specifications for special components or assemblies are included in the applicable sections of this book. To avoid warpage, tighten multi-fastener assemblies in a crisscross fashion, in progressive stages, until full torque is reached. Unless otherwise specified, torque specifications call for clean, dry threads. Components should be at room temperature.

CLUTCH/GEAR SELECTION

IANOSJP I to~ ~

----------------------------The clutch may require tuning depending upon I

where the machine will be operated and the desired handling characteristics. The clutch can be tuned by changing the engagement and shifting speeds. Clutch engagement speed is defined as the engine speed at which the machine first begins to move from a complete stop. Clutch shifting speed is defined as the engine speed reached when the machine has travelled 800 m (2,500 ft) after being started at fullthrottle from a dead stop. Normally, when a machine reaches shifting speed, the vehicle speed increases but the engine speed remains nearly constant. Under unfavorable conditions (wet snow, icy snow, hills, or rough terrain), however, engine speed may decrease after the shifting speed has been reached.

GEAR SELECTION The reduction ratio of the driven gear to the drive gear must be set according to the snow conditions. If there are many rough surfaces or unfavorable snow conditions, the driveldriven gear ratio should be increased. If the surfaces are fairly smooth or better snow conditions exist, decrease the ratio.

Gear ratio chart The drive and driven gears and the chains shown in the gear ratio chart are available as options. The figures containing a decimal point represent the driveldriven gear ratios, while the bottom numbers designate the number of links in the chain.

GENERAL TORQUE SPECIFICATIONSI DEFINITION OF UNITS

GENERAL TORQUE SPECIFICATIONS This chart specifies torque for standard fasteners with standard I.S.0. pitch threads. Torque specifications for special components or assemblies are included in the applicable sections of this book. To avoid warpage, tighten multi-fastener assemblies in a crisscross fashion, in progressive stages, until full torque is reached. Unless otherwise specified, torque specifications call for clean, dry threads. Components should be at room temperature.

BRAKE HOSE INSPECTION 1. Inspect: • Brake hose Cracks/ damage/wear --+ Replace. 2. Check: • Fluid leakage Apply the brake lever several times. Fluid leakage --+ Replace the defective parts.

AIR BLEEDING (HYDRAULIC BRAKE SYSTEM)

~ --------Bleed the brake system in the following cases: • The system has been disassembled. • A brake hose is loosened or removed. • The brake fluid has been very low. • Brake operation is faulty. If the brake system is not properly bled a loss of braking performance may occur. 1. Bleed: • Brake system

Air bleeding steps: • Fill the brake master cylinder reservoirwith the proper brake fluid. • Install the diaphragm. Be careful not to spill any fluid or allow the brake master cylinder reservoir to overflow. • Connect clear plastic hoses CD tightly to the brake caliper bleed screws ®. • Place the other ends of the hoses in a container.

GENERAL TORQUE SPECIFICATIONSI DEFINITION OF UNITS

GENERAL TORQUE SPECIFICATIONS

A

This chart specifies torque for standard fasteners with standard I.S.0. pitch threads. Torque specifications for special components or assemblies are included in the applicable sections of this book. To avoid warpage, tighten multi-fastener assemblies in a crisscross fashion, in progressive stages, until full torque is reached. Unless otherwise specified, torque specifications call for clean, dry threads. Components should be at room temperature.

GEAR SELECTION The reduction ratio of the driven gear to the drive gear must be set according to the snow conditions. If there are many rough surfaces or unfavorable snow conditions, the drive/driven gear ratio should be increased. If the surfaces are fairly smooth or better snow conditions exist, decrease the ratio.

Gear ratio chart The drive and driven gears and the chains shown in the gear ratio chart are available as options. The figures containing a decimal point represent the drive/driven gear ratios, while the bottom numbers designate the number of links in the chain.

ECU'S SELF-DIAGNOSTIC FUNCTION The ECU is equipped with a self-diagnostic function in order to ensure that the engine control system is operating normally. If this function detects a malfunction in the system, it immediately operates the engine under substitute characteristics and illuminates the engine trouble warning light to alert the rider that a malfunction has occurred in the system. Once a malfunction has been detected, a fault code is stored in the memory of the ECU. • To inform the rider that the fuel injection system is not functioning, the engine trouble warning light flashes when the start switch is being pushed to start the engine. • If a malfunction is detected in the system by the self-diagnostic function, this mode provides an appropriate substitute characteristic operation, and alerts the rider of the detected malfunction by flashing an engine trouble warning light. • The fault code number appears from the lowest value in order of precedence on the LCD meter. Once a fault code has been displayed, it remains stored in the memory of the ECU until it is deleted. EAS00900

SUBSTITUTE CHARACTERISTICS OPERATION CONTROL (FAIL-SAFE ACTION) If the ECU detects an abnormal signal from a sensor while the vehicle is being driven, the ECU illuminates the engine trouble warning light and provides the engine with alternate operating instructions that are appropriate for the type of malfunction. When an abnormal signal is received from a sensor, the ECU processes the specified values that are programmed for each sensor in order to provide the engine with alternate operating instructions that enable the engine to continue to operate or stop operating, depending on the conditions. The ECU takes fail-safe actions in two ways: one in which the sensor output is set to a prescribed value, and the other in which the ECU directly operates an actuator. Details on the fail-safe actions are given in the table below. FAIL-SAFE ACTIONS TABLE Fault Code No.

This chart specifies torque for standard fasteners with standard I.S.O. pitch threads. Torque specifications for special components or assemblies are included in the applicable sections of this book. To avoid warpage, tighten multi-fastener assemblies in a crisscross fashion, in progressive stages, until full torque is reached. Unless otherwise specified, torque specifications call for clean, dry threads. Components should be at room temperature.

NOTICE This manual was written by the Yamaha Motor Company primarily for use by Yamaha dealers and their qualified mechanics. It is not possible to put an entire mechanic's education into one manual, so it is assumed that persons using this book to perform maintenance and repairs on Yamaha snowmobiles have a basic understanding of the mechanical concepts and procedures inherent in snowmobile repair. Without such knowledge, attempted repairs or service to this model may render it unfit and/or unsafe to use. Yamaha Motor Company, Ltd. is continually striving to improve all models manufactured by Yamaha. Modifications and significant changes in specifications or procedures will be forwarded to all authorized Yamaha dealers and will, where applicable, appear in future editions of this manual.

Failure to follow WARNING instructions could result in severe injury or death to the snowmobile operator, a bystander, or a person inspecting or repairing the snowmobile.

A CAUTION indicates special precautions that must be taken to avoid damage to the snowmobile.

NOTE: A NOTE provides key information that can make procedures easier or clearer. MANUAL FORMAT All of the procedures in this manual are organized in a sequential, step-by-step format. The information has been compiled to provide the mechanic with an easy to read, handy reference that contains comprehensive explanations of all inspection, repair, assembly, and disassembly operations. In this revised format, the condition of a faulty component will precede an arrow symbol and the course of action required to correct the problem will follow the symbol, e.g., • Bearings Pitting/damage ~ Replace. EXPLODED DIAGRAM Each chapter provides exploded diagrams before each disassembly section to facilitate correct disassembly and assembly procedures.

PERIODIC INSPECTION AND ADJUSTMENT ENGINE ENGINE OIL LEVEL INSPECTION 1. Inspect: • Engine oil level

Do not run the engine with too much or not enough oil in the oil tank. Oil could flow into the intake silencer and the engine could be damaged. Inspection steps: • Place the snowmobile on a level surface and apply the parking brake. • Start the engine, warm it up for 10 -- 15 minutes, and then turn off. • Disconnect the oil level gauge coupler.

Disconnect the oil level gauge coupler before removing the oil level gauge. Otherwise the lead can twist and become severed. • Remove the oil level gauge, wipe it clean, insert it back into the filler hole (without screwing it in), and then remove it again to check the oil level. • The engine oil level should be between the minimum level mark @ and maximum level mark@. Below the minimum level mark ~ Add the recommended engine oil to the proper level.

When adding the engine oil, be careful not to fill above the maximum level mark and minimum level mark on the oil level gauge.

GEAR SELECTION The reduction ratio of the driven gear to the drive gear must be set according to the snow conditions. If there are many rough surfaces or unfavorable snow conditions, the drive/driven gear ratio should be increased. If the surfaces are fairly smooth or better snow conditions exist, decrease the ratio.

Gear ratio chart The drive and driven gears and the chains shown in the gear ratio chart are available as options. The figures containing a decimal point represent the drive/driven gear ratios, while the bottom numbers designate the number of links in the chain.

FRONT SHOCK ABSORBER AIR PRESSURE (Except for RXW10GTW) This snowmobile is equipped with FOX shock absorbers as standard equipment. The air pressure of the shock absorbers can be adjusted using the special pump GD included with your snowmobile. NOTE: _ The following procedure applies to both shock absorbers. 1. Place the snowmobile on a level surface and apply the parking brake. 2. Lift the front of the snowmobile onto a suitable stand to raise the skis off the ground.

15


FRONT SHOCK ABSORBER AIR PRESSURE (Except for RXW10GTW)

INSP ADJ

~ ----------

Support the snowmobile securely on a suitable stand before adjusting the shock absorbers.

Make sure that there is no load on the shock absorbers and that they are fully extended before making any air pressure adjustments. 3. Remove the air valve cap ÂŽ from the shock absorber. 4. Install the hose connector ÂŽ of the special pump onto the air valve of the shock absorber and tighten it approximately six turns until the pressure registers on the pump gauge.

Do not overtighten the connector onto the air valve as this will damage the connector seal.

_--J----LJ--...-.....--.=O

NOTE:

_

If the shock absorber has no air pressure, the gauge reading will be zero. 5. To increase the air pressure, operate the pump a few times. The pressure should increase slowly. If the pressure increases rapidly, check to make sure that the pump is properly connected and tightened onto the air valve. To decrease the air pressure, push the black bleed valve button @. NOTE: _ To allow pressure to escape from the pump and the shock absorber, push the button halfway down and hold it. To allow only a small amount of pressure to escape, push the button all the way down and quickly release it.

6. Remove the hose connector from the air valve. NOTE: _ When removing the connector, the sound of air escaping may be heard, but this is from the pump hose, not the shock absorber.

Air pressure range: 345 kPa (3.4 kgf/cm 2 , 50 psi) to 1,034 kPa (10.3 kgf/cm 2 , 150 psi) Recommended air pressure: 483 kPa (4.8 kgf/cm 2 , 70 psi)

Do not exceed 1,034 kPa (10.3 kgf/cm 2 , 150 psi) 7. Install the air valve cap. NOTE:

_

If the front suspension bottoms too easily or rolls too much during cornering, increase the air pressure by 34 kPa (0.3 kgf/cm 2 , 5 psi). If the suspension is too firm and you want a more compliant ride, decrease the air pressure by 34 kPa (0.3 kgf/cm 2 , 5 psi)

The air pressure of the left and right shock absorbers must be set to the same setting. Uneven settings can cause poor handling and loss of stability.

~ ----------

This shock absorber contains highly pressurized nitrogen gas. It could explode by improper handling, causing injury or property damage. • Do not tamper with or attempt to open the shock absorber. • Do not subject the shock absorber to an open flame or other high heat source, which could cause it to explode. • Do not deform or damage the shock absorber in any way. • Do not dispose of a worn or damaged shock absorber by yourself. Take the unit to a Yamaha dealer.

FEATURES

GENERAL INFORMATION FEATURES OIL PRESSURE SENSING SYSTEM This model is equipped with an oil pressure sensing system. When the oil pressure drops, the rpm limiter is activated, and the engine rpm is reduced, or the engine is shut off, if necessary. If the oil pressure is incorrect upon starting the engine 1. "OP-LO" CD appears and the oil level/pressure warning indicator ÂŽ illuminates on the meter display.

2. When the two items, above, are displayed, they indicate the rpm limiter is in operation; the rpm is reduced to less than or equal to the clutch engagement rpm, even though the throttle is open. If the incorrect oil pressure persists, the engine stops automatically after approximately one minute. 3. When the oil pressure stabilizes to the correct level, the limiter is automatically canceled as long as the throttle is not operated and then "OP-LO" disappears and the oil level/pressure warning indicator goes off. 4. Note that it may take a few seconds for the oil pressure to rise to the optimum level after the engine is started, even in normal conditions. If the meter display described in (1.) is no longer displayed after a few seconds, this indicates that everything is normal. TIP _ When disassembling the engine, replacing the engine oil or oil filter, etc., if the oil is drained entirely from the piping, there may be delay before the oil pressure rises.

The clutch can be tuned by changing the engagement and shifting speeds. Clutch engagement speed is defined as the engine speed at which the snowmobile first begins to move from a complete stop. Shifting speed is defined as the engine speed reached when the snowmobile has travelled 800 m (2,500 ft) after being started at full-throttle from a dead stop. Normally, when a snowmobile reaches shifting speed, the snowmobile speed increases but the engine speed remains nearly constant. Under unfavorable conditions (wet snow, icy snow, hills, or rough terrain), however, engine speed may decrease after the shifting speed has been reached.

High altitude tuning Atmospheric pressure decreases and engine output becomes low at high altitude locations. Because of this, clutch engagement speed and shifting speed also decrease and unable to maximize the engine output power. To maximize the engine output, tuning for increasing clutch engagement speed and shifting speed is necessary. This setting is called high altitude tuning. The following changes are usually performed in high altitude tuning. • To increase the clutch engagement and shifting speed, changing to a larger spring constant or using lighter weights and rivets. (decreasing primary sheave thrust) • Increasing the reduction ratio of the driven gear/drive gear. (increasing the driving performance) Refer to "HIGH ALTITUDE TUNING".

Spring rate

® Weight

Shape, weight

Impact on the shifting function • A larger preload increases the clutch engagement speed, and the shifting speed tends to rise accordingly. Shifting tends to become somewhat harder. (increasing the spring reaction force) • A smaller preload decreases the clutch engagement speed, and the shifting speed tends to drop accordingly. Shifting tends to become somewhat easier. (decreasing the spring reaction force) • A larger spring rate increases the shifting speed. It also slightly increases the clutch engagement speed. Shifting tends to become somewhat harder. (increasing the spring reaction force) • A smaller spring rate decreases the shifting speed. It also slightly decreases the clutch engagement speed. Shifting tends to become somewhat easier. (decreasing the spring reaction force) Shape and weight determine, the size of moment about the center of the weight rotation when the sheave is running. • Heavier weight decreases the clutch engagement and shifting speed. Shifting tends to become somewhat easier. (increasing the sheave thrust) • Lighter weight increases the clutch engagement and shifting speed. Shifting tends to become somewhat harder. (decreasing the sheave thrust)

Impact on the shifting function Rivets are fastened through the hole in the weight. • Using more rivets decreases the clutch engagement and shifting speed. Shifting tends to become somewhat easier. (increasing the sheave thrust) • Using less rivets increases the clutch engagement and shifting speed. Shifting tends to become somewhat harder. (decreasing the sheave thrust) The outside diameter affects the contact angle with the weight. • A smaller diameter decreases the clutch engagement speed. (increasing the sheave thrust) • A larger diameter increases the clutch engagement speed. (decreasing the sheave thrust) • Using more shims increases the preload and clutch engagement speed. (increasing the spring reaction force) • Using less shim decreases the preload and clutch engagement speed. (decreasing the spring reaction force)

• A larger preload, spring rate or twist angle increases the shifting speed and makes shifting somewhat harder. (increasing the sheave thrust) • A smaller preload, spring rate or twist angle decreases the shifting speed and makes shifting somewhat easier. (decreasing the sheave thrust) One of the holes may be used selectively to change the spring twist angle (preload). Refer to "@ Spring".

INSP ADJ

Impact on the shifting function The cam angle determines the degree of sensitivity of load torque detection. • A smaller cam angle increases sensitivity, which in turn increases the sheave thrust to make back shifting easier. The shifting speed tends to increase and shifting becomes somewhat harder. (increasing the sheave thrust) • A larger cam angle makes back shifting harder. The shifting speed tends to decrease and shifting becomes somewhat easier. (decreasing the sheave thrust) Size of the secondary sheave clearance (between fixed sheave and sliding sheave) can be adjusted by the number of shims used. Adjust the clearance when the V-belt wear deteriorates and belt width becomes smaller. • Using more shims makes secondary sheave clearance smaller. • Using less shim makes secondary sheave clearance larger. When the V-belt width is smaller, wrap-around diameter of the V-belt on the primary sheave is larger and clutch engagement speed is slightly increased.

GEAR SELECTION The reduction ratio of the driven gear to the drive gear must be set according to where the snowmobile will be operated and driving conditions. If the load on the snowmobile is big such as driving at high altitude mountain or towing, the driven/drive gear ratio should be increased. If the load on the snowmobile is small such as driving on the fairly smooth surfaces or hard-compacted snow, decrease the ratio.

Air Pressure RX10PSA

The left and right shock absorber air pressure must be set to the same setting. Uneven settings can cause poor handling and loss of stability. This snowmobile is equipped with FOX shock absorbers as standard equipment. The air pressure of the shock absorbers can be adjusted using the shock absorber pump CD included with your snowmobile. This shock absorber pump has low pressure gauge ® and high pressure gauge @.

Low pressure gauge measuring range: o kPa (0 kgf/cm 2 , 0 psi) to 620 kPa (6.2 kgf/cm 2 , 90 psi) High pressure gauge measuring range: o kPa (0 kgf/cm 2 , 0 psi) to 2,068 kPa (20.7 kgf/cm 2 , 300 psi)

Adjustment steps:

~----------

Support the snowmobile securely on a suitable stand before adjusting the shock absorbers.

Make sure that there is no load on the shock absorbers and that they are fully extended before making any air pressure adjustments. • Place the snowmobile on a level surface and apply the parking brake. • Lift the front of the snowmobile onto a suitable stand to raise the skis off the ground. • Remove the air valve cap CD from the shock absorber. 35

• Install the hose connector ® of the shock absorber pump to the shock absorber air valve. TIP _ When installing, make sure the shock absorber pump lever ® is down as shown in the illustration.

Do not overtighten the connector onto the air valve as this will damage the connector seal. • Lift up the shock absorber pump lever @. TIP _ • Use the low pressure gauge © of the shock absorber pump and measure. ·If the shock absorber has no air pressure, the gauge reading will be zero. • To increase the air pressure, operate the pump a few times. The pressure should increase slowly. If the pressure increases rapidly, check to make sure that the pump is properly connected and tightened onto the air valve. To decrease the air pressure, push the bleed valve button @. TIP _ To allow pressure to escape from the pump and the shock absorber, push the button halfway down and hold it. To allow only a small amount of pressure to escape, push the button all the way down and quickly release it. • Lay flat the shock absorber pump lever. • Remove the hose connector from the air valve. TIP _ When removing the connector, the sound of air escaping may be heard, but this is from the pump hose, not the shock absorber.

Air pressure range: 448 - 1,034 kPa (4.5 - 10.3 kgf/cm 2 , 65 - 150 psi) Standard air pressure: 586 kPa (5.9 kgf/cm 2 , 85 psi)

~O~

~ I

TROUBLESHOOTING (SKI, SUSPENSION) This section will point you towards possible solutions for resolving handling or ride comfort complaints. When making adjustments, do it in a small increments. Also, in general, making just one adjustment may not correct the problem. You may need to make several small adjustments to get the best overall results. Keep in mind that how the snowmobile handles going down the trail is usually controlled by the front suspension, the center shock, and the limiter straps. How the snowmobile rides (ride comfort) is usually controlled by the rear shock. Also, remember that snowmobile suspension adjustments may involve compromises. Tuning a snowmobile to do one thing very well may come at the sacrifice of something else. For example, if the snowmobile is setup to provide optimum weight transfer for best acceleration, this same setting will not be ideal for trail riding, because excessive under steering may be experienced during cornering. You must have a good working knowledge of the suspension and tune the suspension to provide best overall balance for specific conditions and usages. SYMPTOM DESCRIPTION POSSIBLE CAUSE Front of the snowmobile darts • Too much weight on skis. from side to side on a straightaway.

Under steering - front end (skis) pushes when cornering.

• Skis out of alignment. • Loose steering ball joints. • Too much carbide on ski runners. • Worn or missing carbides on ski runners. • Not enough weight on skis.

Over steering. Front end (skis) • Too much weight on skis. bites too much during cornering - rear of the snowmobile starts to come around.

Heavy steering - excessive force is needed to turn the handlebars.

• Too much carbides on ski runners. • Too much weight on skis.

• Too much carbides on ski runners. • Steering linkage binding.

49

POSSIBLE REMEDY • Extend limiter straps and/or increase center shock spring preload or reduce rear shock spring preload or reduce front shock spring preload. • Adjust "ski-toe-out." • Replace worn ball joints. • Use ski runners with less earbide. • Replace carbide runners. • Reduce center shock spring preload and/or shorten limiter straps. Increase front shock spring preload. • Extend limiter straps and/or increase center shock spring preload or reduce rear shock spring preload or reduce front shock spring preload. • Use ski runners with less earbides. • Extend limiter straps and/or increase center shock spring preload or reduce rear shock spring preload or reduce front shock spring preload. • Use ski runners with less earbides. • Clean and lubricate steering ball joints and column.


TROUBLESHOOTING (SKI, SUSPENSION) SYMPTOM DESCRIPTION Front suspension bottoming out frequently.

Front suspension is too harsh over small bumps.

If this function detects a malfunction in the system, it immediately operates the engine under substitute characteristics and the warning light and self-diagnostic warning indicator on the upper LCD flash to alert the rider that a malfunction has occurred in the system. Once a malfunction has been detected, a fault code is stored in the memory of the ECU. • If a malfunction is detected in the system by the self-diagnostic function, the ECU provides an appropriate substitute characteristic operation, and the warning light and self-diagnostic warning indicator on the upper LCD flash to alert the rider of the detected malfunction. • The lowest fault code number appears on the lower LCD. Once a fault code has been displayed, it remains stored in the memory of the ECU until it is deleted. SELF-DIAGNOSTIC FUNCTION TABLE If the ECU detects an abnormal signal from a sensor while the snowmobile is being driven, the warning light and self-diagnostic warning indicator on the upper LCD flash to alert the rider that a malfunction has occurred and the ECU provides the engine with alternate operating instructions that are appropriate for the type of malfunction. When an abnormal signal is received from a sensor, the ECU processes the specified values that are programmed for each sensor in order to provide the engine with alternate operating instructions that enable the engine to continue to operate or stop operating, depending on the conditions.

ELECTRICAL SWITCH INSPECTION SWITCH INSPECTION Use a pocket tester to check the terminals for continuity. If the continuity is faulty at any point, replace the switch. Analog pocket tester: YU-03112-C Pocket tester: 90890-03112 TIP

_

• Set the pocket tester to "0" before starting a test. • When testing the switch for continuity the pocket tester should be set to the "x 1 n" range. • When checking the switch turn it on and off a few times.

• For waterproof couplers, never insert the tester probes directly into the coupler. When performing any checks using a waterproof coupler, use the specified test harness or a suitable commercially available test harness. • Precautions when removing/installing the sensor coupler. When removing/installing the coupler, carefully wipe peripheral components with a soft cloth. Be careful to prevent liquid such as water or oil from dropping into the coupler. If water or oil comes into contact with the coupler, this may result in a sensor malfunction. The same also applies to other FI-related sensors.

EPS CONTROL UNIT'S SELF-DIAGNOSTIC FUNCTION The EPS control unit is equipped with a self-diagnostic function. If this function detects a malfunction in the EPS system, it lights the EPS warning display to alert the rider that a malfunction has occurred in the system. Once a malfunction has been detected, it becomes stored in the EPS control unit memory in the form of a fault code. - The EPS warning display comes on when the main switch is turned to "ON", and then goes off once the engine is started. If the warning light remains on or comes on after the engine is started, the EPS system may be defective. - The electrical circuit of the warning display can be checked by turning the main switch to "ON". If the warning display does not come on, the electrical circuit may be defective.

CD EPS warning display

TIP

_

-If the engine is stopped using the engine stop switch and the main switch is in the "ON" position, the EPS warning display comes on to indicate that the power assistance for the steering is not functioning. -If the steering usage is too heavy (i.e., excessive steering use when the snowmobile is traveling at a slow speed), the power assist is reduced to protect the EPS motor from overheating.

EPS WARNING DISPLAY DURING NORMAL OPERATION The EPS warning display comes on initially for 2 seconds after the main switch is turned to "ON". However, the warning display remains on until the engine is started. In addition, if a malfunction is detected while the warning light comes on initially, the warning light remains on. Furthermore, the warning display comes on whenever a malfunction has occurred. TIP _ The EPS system does not operate while the EPS warning display is on.

This chart specifies torque for standard fasteners with standard I.S.0. pitch threads. Torque specifications for special components or assemblies are included in the applicable sections of this book. To avoid warpage, tighten multi-fastener assemblies in a crisscross fashion, in progressive stages, until full torque is reached. Unless otherwise specified, torque specifications call for clean, dry threads. Components should be at room temperature.
