INTRODUCTION

Safety rules - Ecology and the environment MaizeMaster 9105-24

APAC

Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the treatment of some of the substances that advanced technology requires, sound judgment should govern the use and disposal of products of a chemical and petrochemical nature. Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this legislation. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze, cleaning agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use, and dispose of these substances.

Helpful hints • Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems may cause considerable spillage. • In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products contain substances that may be harmful to your health. • Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems. • Avoid spillage when you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid, etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of the fluids in a proper way that complies with all local legislation and available resources. • Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly. • The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-conditioning specialist or use a special extractor to recharge the system properly. • Repair any leaks or defects in the engine cooling system or hydraulic system immediately. • Do not increase the pressure in a pressurized circuit as this may lead to a component failure. • Protect hoses during welding. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils, coolant, etc.

Battery recycling Batteries and electric accumulators contain several substances that can have a harmful effect on the environment if the batteries are not properly recycled after use. Improper disposal of batteries can contaminate the soil, groundwater, and waterways. NEW HOLLAND strongly recommends that you return all used batteries to a NEW HOLLAND dealer, who will dispose of the used batteries or recycle the used batteries properly. In some countries, this is a legal requirement.

Mandatory battery recycling NOTE: The following requirements are mandatory in Brazil. Batteries are made of lead plates and a sulfuric acid solution. Because batteries contain heavy metals such as lead, CONAMA Resolution 401/2008 requires you to return all used batteries to the battery dealer when you replace any batteries. Do not dispose of batteries in your household garbage. Points of sale are obliged to: • Accept the return of your used batteries • Store the returned batteries in a suitable location • Send the returned batteries to the battery manufacturer for recycling

Shimming For each adjustment operation, select adjusting shims and measure the adjusting shims individually using a micrometer, then add up the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value shown on each shim.

Rotating shaft seals For correct rotating shaft seal installation, proceed as follows: 1. Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes. 2. Thoroughly clean the shaft and check that the working surface on the shaft is not damaged. 3. Position the sealing lip facing the fluid. NOTE: With hydrodynamic lips, take into consideration the shaft rotation direction and position the grooves so that they will move the fluid towards the inner side of the seal. 4. Coat the sealing lip with a thin layer of lubricant (use oil rather than grease). Fill the gap between the sealing lip and the dust lip on double lip seals with grease. 5. Insert the seal in its seat and press down using a flat punch or seal installation tool. Do not tap the seal with a hammer or mallet. 6. While you insert the seal, check that the seal is perpendicular to the seat. When the seal settles, make sure that the seal makes contact with the thrust element, if required. 7. To prevent damage to the seal lip on the shaft, position a protective guard during installation operations.

O-ring seals Lubricate the O-ring seals before you insert them in the seats. This will prevent the O-ring seals from overturning and twisting, which would jeopardize sealing efficiency.

Sealing compounds Apply a sealing compound on the mating surfaces when specified by the procedure. Before you apply the sealing compound, prepare the surfaces as directed by the product container.

Protecting the electronic and/or electrical systems during charging and welding To avoid damage to the electronic and/or electrical systems, always observe the following practices: 1. Never make or break any of the charging circuit connections when the engine is running, including the battery connections. 2. Never short any of the charging components to ground. 3. Always disconnect the ground cable from the battery before arc welding on the machine or on any machine attachment. • Position the welder ground clamp as close to the welding area as possible. • If you weld in close proximity to a computer module, then you should remove the module from the machine. • Never allow welding cables to lie on, near, or across any electrical wiring or electronic component while you weld. 4. Always disconnect the negative cable from the battery when charging the battery in the machine with a battery charger. NOTICE: If you must weld on the unit, you must disconnect the battery ground cable from the machine battery. The electronic monitoring system and charging system will be damaged if this is not done. 5. Remove the battery ground cable. Reconnect the cable when you complete welding.

WARNING Battery acid causes burns. Batteries contain sulfuric acid. Avoid contact with skin, eyes or clothing. Antidote (external): Flush with water. Antidote (eyes): flush with water for 15 minutes and seek medical attention immediately. Antidote (internal): Drink large quantities of water or milk. Do not induce vomiting.

INTRODUCTION

Chain wear tables - Roller chain MaizeMaster 9105-24

APAC

As the individual joints in a roller chain enter and leave a sprocket articulation occurs at the pins and bushings of the roller chain. This articulation results in wear on the pins and bushings. Roller chains do not stretch rather the material wears away from pin and bushing and causes the roller chain to elongate gradually. Critical dimensions of the roller chain are as follows: • (1) 2X pitch • (2) Wear plus 2X pitch • (3) Elongation due to pin and bushing wear Elongation is normal. Proper lubrication and proper drive maintenance will minimize the rate of wear and elongation.

12555627A

96091469

The rate of wear is dependent upon: • The relationship between the load and the amount of bearing area between pin and bushing. • The material condition of the bearing surfaces. • The adequacy of lubrication. • The frequency and degree of articulation between pins and bushings. NOTE: The quantity of sprockets in the drive, the speeds of the sprockets, the number of teeth, and the length of the chain in pitches determines the frequency and degree of articulation between pins and bushings. Use the above figure to gather an accurate wear measurement (1). Measure as closely as possible from the center of one pin to the center of another. The more pitches (pins) contained within the measurement increase the accuracy. Replace the roller chain if the measured value exceeds the nominal replace value by more than the allowable percentage. See the wear limits on roller chain table. The maximum allowable wear elongation is approximately 3% for most industrial applications, based upon sprocket design. The allowable chain wear in percent can be calculated using the relationship: 200/ (N), where (N) is the number of teeth in the large sprocket. This relationship is often useful since the normal maximum allowable chain wear elongation of 3% is valid only up to 67 teeth in the large sprocket. The wear limit is approximately 1.5% in the following: • Fixed center distance drives. • Roller chains running in parallel. • Roller chains with a smoother operation requirement. For example, if you measure 12 pitches (12 pins) of a #80 chain and the length is 313.944 mm (12.360 in) or greater (using 3% as the maximum allowable wear), you should replace the chain. Anything less than 313.944 mm (12.360 in) is acceptable by most industrial standards.

WARNING Avoid injury! Use Personal Protective Equipment (PPE), including protective goggles, gloves, and safety footwear. Failure to comply could result in death or serious injury. W1036A

NOTICE: Do not aggressively drive out the hub from the housing in order to prevent a mass ejection of the cam pins and springs. The pins and springs must be removed in an ordered manner in order to reproduce the factory set-up. NOTE: In the following step the hex bushing (1) Figure 7 rotates and can move inward as the hub (2) is displaced when servicing, but the bushing might not be able to readily slide outward due to contact wear on the outer end. If this is the case, then a hex shaft driver will be required as opposed to a round stock driver.

7. Begin to slowly and incrementally drive out the hub. Use a dead-blow mallet (1) and an appropriate length of 30 mm or 1-1/8 in hex shaft bar stock as a driver (2), inserted through the rear opening (3) of the clutch housing. If the hex bushing was removed, round bar stock or a cylinder with an 38 mm (1.5 in) outside diameter can be used as a driver.

8. Continue to slowly and incrementally drive the hub (1) outward until the top contact surface of the cam pins (2) are exposed about half the width of the cam pin.

58.4 [58.218] / 12

Attachments/Headers - Corn header feeder structure

9. Adjust a 102 mm (4.0 in) hose clamp (1) to fit over the exposed cam pins (2). Ensure the clamp covers all the pins (2) in the radial row. Tighten the clamp to fit snugly against the pins. Continue to slowly drive out the hub, exposing more of the first (outside) row of pins. Push the hose clamp evenly over the fully exposed pins.

83074982

83075001

83075003

10. Continue to slowly drive the hub outward (A) to fully expose the first row of clamped pins (B) and half of the next row of pins. Fully loosen the hose clamp adjustment screw (1) relieving all spring pressure on the cam pins. Do not slide the clamp off the pins at this time, as those pins oriented at the underside of the hub may fall from the hub resulting in possible loss of internal spring(s) and/or inner and outer spring(s) assembly pattern.

11. Determine a lengthwise starting row (A) and clockwise or counter-clockwise direction (B) around the hub to be used repeatedly for the removal of each radial row of pins and springs.

12. Create a method, such as the sample table below, for charting the position of each pin with either an outer (single) spring or with both an outer and inner (double) spring configuration. NOTE: The distribution of inner springs may follow a varied pattern. If a spring or springs may have been lost during disassembly, look for a distribution pattern to follow for replacing the lost spring(s). A balanced distribution is the goal, though occasionally a clutch may contain an odd distribution quantity of inner springs. The nominal inner spring quantity is seven. When replacing the springs it is recommended to install the same quantity of inner springs charted at disassembly but not exceed the nominal quantity of seven.

Rotate the removal of the hose clamp as the pins and springs are individually removed. Check the hub as each pin is removed that an inner spring is not remaining in the hub pocket. Chart the spring distribution. 13. Slide the hose clamp over the next row of partially exposed cam pins; snug the clamp ensuring all pins are captured by the clamp, and then repeat the driving, clamping, pin and spring removal, and charting procedure for the remaining row. Support the hub when driving the hub outward on the last row.

Prior operation: Torque limiter - Remove - Slip clutch for feed auger drive system (58.218)

External housing inspection 1. Clean the exterior clutch housing. Inspect the clutch assembly for discolored or scorched paint. NOTE: Typically, this clutch should not experience large amounts of heat. Any indication of exterior scorching indicates that the clutch has operated excessively resulting in an internal failure producing excessive heat that will have affected the internal parts, causing them to lose their hardness. Corrective action to the header unit and complete slip clutch replacement maybe required. Next operation: As required, Torque limiter - Disassemble - Slip clutch for feed auger drive system (58.218) , and then Torque limiter - Inspect - Slip clutch internal components (58.218) .

Torque limiter - Check - Slip clutch torque slippage (feed auger) MaizeMaster 9105-24

APAC

Prior operation: Torque limiter - Remove - Slip clutch for feed auger drive system (58.218) NOTE: Torque can not be accurately or reliably checked with standard torque measuring tools. The slip clutch torque is factory measured and set by the use of specialized constant rotation computer torque measuring equipment. Accurate or reliable torque measurements can not be obtained with standard torque wrenches. The row unit slip clutch is designed with a slippage torque of 500 Nm (369 lb ft), plus or minus 10%. When the slip clutch torque has dropped to an unacceptable level of slippage during normal header operation, replacement or rebuilding of the clutch is recommended. New replacement cam pins and installation of new outer and inner springs to factory set configurations of the inner springs is the best method to return the clutch to original performance characteristics, without replacing the entire unit. Reduced slippage torque is generally a result of excessive wear to the following components; these parts are listed in order of the likeliness to be the cause of reduced performance: 1. Cam pins – rounded over contact surface, discolored by excessive heat — Service parts available 2. Springs (outer and inner) – cracked or broken — Service parts available 3. Hub pockets – holes elongated or oblong and/or burred — Cylinder hub is not serviced separately, must replace entire clutch unit. 4. Internal housing walls – distinct grooves, burrs — Clutch housing is not serviced separately, must replace entire clutch unit. NOTE: The clutch housing is manufactured to be extremely durable. Replacement of the housing should be the last component item needing replacement provided adequate lubrication is maintained. Next operation: As required, Torque limiter - Disassemble - Slip clutch for feed auger drive system (58.218) or Torque limiter Install - Slip clutch (58.218) .

Component inspection NOTE: For best renewed clutch performance rebuild the clutch with all new springs and cam pins. Some or all components can be inspected and reused if they meet the specifications below, but performance longevity and slippage torque is compromised. 1. Clean all parts in a suitable cleaning solvent and air dry. Inspect and replace all internal parts that indicate excessive wear, damage, or discoloration from heat. 2. Cam pins are the most common replacement clutch component. The contact surfaces indicated by (1) (2), and (3) show varying degrees of wear from new (A), moderate wear (B), to excessively worn (C). Use a 0 – 25 mm (0 – 1.0 in) Micrometer to measure the cam pin specifications: • Height (D) = 15.5 – 17.5 mm (0.61 – 0.69 in) The contact surface should have distinct edges as indicated by (1). • Outside Diameter (E) = 16 mm (0.63 in) The pin body cylinder (E) should be round, not oblong.

63075012

73075011

3. Inspect the inner springs (1) and outer springs (2) for heat discoloration or cracks. Use a 0 – 25 mm (0 – 1.0 in) Micrometer to measure the springs to ensure they meet the following dimensional specifications:

4. Handle the hub (1) carefully. The outer edge openings, (2) of the pin pockets in the hub are sharp. Inspect the hub cam pin pockets (3) for burrs that can restrict pin movement and inspect the pocket shape to be round, not oblong. Lightly file away any burrs and clean any filings from the hub that can contaminate the lubricant during assembly. Visually inspect the hub pocket openings (2) to be round, (A) (solid line), not oblong, (B) (dotted line). Use an Internal Micrometer to verify shape. If pockets are deformed, entire clutch assembly must be replaced. The hub is not available as a serviceable replacement part. 83075005

83075004

5. Inspect the clutch housing internal surfaces (1). Inspect the clutch pin contact surfaces of the housing for excessive wear. Replace the housing when the cam corners are rounded or discernible grooves are present where the pins press against the housing. The housing is not available as a serviceable replacement part.

10. Slide the 102 mm (4.0 in) hose clamp (1) over the pins (2) covering one-half of the pin diameter. NOTE: Make sure that the hose clamp is covering all of the pins equally. 11. Tighten the hose clamp adjustment screw (3) until the cam pins are almost fully compressed into the hub. NOTE: Make sure that each of the pin contact surfaces are in straight alignment with the linear row (A).

83075007

83074989

12. Position the clutch housing (1) in a vise or on a stable work surface vertically with the opening facing upward. 13. Position the hub with the installed last row of pins into the housing opening and the pins aligned with the housing cam slots. 14. Tighten the hose clamp adjustment screw to ensure the pins are compressed into the hub creating a gap (2) between the pin and the housing (3). NOTE: Make sure that the pins will not contact the housing outer edge. Make sure that the up is vertical in the housing and not canted to one side.

NOTICE: The hardened metal properties of the clutch housing outer edge can shave the new edges of the cam pins, when the hub is driven into the housing, thus ruining the performance characteristics of the clutch and potentially contaminating the lubricant with metallic shavings. 15. Use a soft face dead blow mallet, to drive the hub (1) slowly into the housing until the pins are released from the hose clamp (2) and snap into the respective cam slots of the housing.

1. Position the cross in the yoke so that the bearing journals are in each yoke ear. Insert the bearings in the outside of the yoke ears, and position the assembly in a vise. Press the bearings in until they are flush with the edge of the yoke. 2. Using a socket (1) of the same diameter as the bearing, press the bearing into the yoke ear until the snap ring groove is exposed on the inside of the yoke ear. Install the snap ring over the bearing cup. 3. Reposition the yoke and cross in the vise, and use the socket to press the opposite bearing fully into the yoke ear while rotating the cross to ensure it does not bind. 4. Press the bearing into the yoke ear until the snap ring can be installed. It may be necessary to push the bearing in as far as possible with the vise, and then remove the yoke assembly. 5. Strike the yoke ears with a sharp blow from a hammer to spring the yoke enough to install the snap ring.

Slip clutch - Check - Torque slippage (row unit) MaizeMaster 9105-24

APAC

Prior operation: Remove the slip clutch. Reference: Slip clutch - Remove - Slip clutch - Row unit drive system (58.224) NOTICE: Torque can not be accurately or reliably checked with standard torque measuring tools. The slip clutch torque is factory measured and set by the use of specialized constant rotation computer torque measuring equipment. Accurate or reliable torque measurements can not be obtained with standard torque wrenches. The row unit slip clutch is designed with a slippage torque of 750 Nm (553 lb ft), plus or minus 10%. When the slip clutch torque has dropped to an unacceptable level of slippage during normal header operation, replacement or rebuilding of the clutch is recommended. New replacement cam pins and installation of new outer and inner springs to factory set configurations of the inner springs is the best method to return the clutch to original performance characteristics, without replacing the entire unit. Reduced slippage torque is generally a result of excessive wear to the following components; these parts are listed in order of the likeliness to be the cause of reduced performance: 1. cam pins – rounded over contact surface, discolored by excessive heat; Service Parts available 2. springs (outer and inner) – cracked or broken; Service Parts available 3. hub pockets – holes elongated or oblong and/or burred; Cylinder Hub is not serviced separately, must replace entire clutch unit. 4. internal housing walls – distinct grooves, burrs; Clutch Housing is not serviced separately, must replace entire clutch unit. NOTE: The clutch housing is manufactured to be extremely durable. Replacement of the housing should be the last component item needing replacement provided adequate lubrication is maintained.

CAUTION Avoid injury! Handle all parts carefully. Do not place your hands or fingers between parts. Use Personal Protective Equipment (PPE) as indicated in this manual, including protective goggles, gloves, and safety footwear. Failure to comply could result in minor or moderate injury. C0145A

WARNING Spring under tension! Compressed springs have potentially dangerous stored energy. Always assemble and disassemble properly. Failure to comply could result in death or serious injury. W0356A

Mount the clutch housing (1) horizontally in a vise. NOTE: The slip clutch springs are compressed and under extreme pressure. Cam pins and springs will violently eject from the hub unless caution is used in performing the disassembly procedure. NOTICE: Do not aggressively drive out the hub from the housing in order to prevent a mass ejection of the cam pins and springs. The pins and springs must be removed in an ordered manner in order to reproduce the factory set-up.

7. Continue to slowly and incrementally drive the hub (1) outward until the top contact surface of the cam pins (2) are exposed about half the width of the cam pin.

8. Adjust a 102 mm (4.0 in) hose clamp (1) to fit over the exposed cam pins (2). Ensure the clamp covers all the pins (2) in the radial row. Tighten the clamp to fit snug against the pins. Continue to slowly drive out the hub, exposing more of the first (outside) row of pins. Push the hose clamp evenly over the fully exposed pins.

9. Continue to slowly and incrementally drive the hub outward (A) to fully expose the first row of clamped pins (B) and half of the next row of pins. Fully loosen the hose clamp adjustment screw (1) relieving all spring pressure on the cam pins. Do not slide the clamp off the pins at this time, as those pins oriented at the underside of the hub may fall from the hub resulting in possible loss of internal spring(s) and/or inner and outer spring(s) assembly pattern.

10. Determine a lengthwise starting row (A) and clockwise or counterclockwise direction (B) around the hub to be used repeatedly for the removal of each radial row of pins and springs.

83074983

83074986

11. Create a method, such as the sample table below, for charting the position of each pin with either an outer (single) spring or with both an outer and inner (double) spring configuration. NOTE: The distribution of inner springs may follow a varied pattern. If a spring or springs may have been lost during disassembly, look for a distribution pattern to follow for replacing the lost spring(s). A balanced distribution is the goal, though occasionally a clutch may contain an odd distribution quantity of inner springs. The nominal inner spring quantity is eleven. When replacing the springs it is recommended to install the same quantity of inner springs charted at disassembly but not exceed the nominal quantity of eleven.

Rotate the removal of the hose clamp as the pins and springs are individually removed. Check the hub as each pin is removed that an inner spring is not remaining in the hub pocket. Chart the spring distribution. 12. Slide the hose clamp over the next row of partially exposed cam pins; snug the clamp ensuring all pins are captured by the clamp, and then repeat the driving, clamping, pin and spring removal, and charting procedure for the remaining two rows. Support the hub when driving the hub outward on the last row.

Slip clutch - Inspect Slip clutch- Internal components (row unit slip clutch) MaizeMaster 9105-24

APAC

Component inspection NOTICE: For best renewed clutch performance rebuild the clutch with all new springs and cam pins. Some or all components can be inspected and reused if they meet the specifications below, but performance longevity and slippage torque is compromised. 1. Clean all parts in a suitable cleaning solvent and air dry. Inspect and replace all internal parts that indicate excessive wear, damage, or discoloration from heat. 2. Cam pins are the most common replacement clutch component. The contact surfaces indicated by (1), (2), and (3) show varying degrees of wear from new (A), moderate wear (B), to excessively worn (C). Use a 0 – 25 mm (0 – 1.0 in) Micrometer to measure the cam pin specifications: • Height (D) = 15.5 – 17.5 mm (0.61 – 0.69 in) The contact surface should have distinct edges as indicated by (1). • Outside Diameter (E) = 16 mm (0.63 in) The pin body cylinder (E) should be round, not oblong.

4. Handle the hub (1) carefully. The outer edge openings, (2) of the pin pockets in the hub are sharp. Inspect the hub cam pin pockets (3) for burrs that can restrict pin movement. Lightly file away any burrs and clean any filings from the hub that can contaminate the lubricant during assembly. Visually inspect the hub pocket openings (2) to be round, (A) (solid line), not oblong, (B) (dotted line). Use an Internal Micrometer to verify shape. If pockets are deformed, entire clutch assembly must be replaced; the hub (1) is not available as a serviceable replacement part.

5. Inspect the internal grease seal (1) installed in place. Replace seal only if it shows evidence of damage. When replacing a damaged seal pry out and discard the old seal, and then evenly press in a new seal. NOTICE: Do not pry at or remove the seal unless damaged and requires replacement. Install the new seal carefully; it can be easily damaged. If seal is pried, it is likely to be damaged and will require replacement.

6. Inspect the clutch housing internal surfaces (1). Inspect the clutch pin contact surfaces of the housing for excessive wear. Replace the housing when the cam corners are rounded or discernible grooves are present where the pins press against the housing; the housing is not available as a serviceable replacement part.

3. Apply a light coating of NEW HOLLAND AMBRA HI TEMP EP GREASE (NLGI#2 lithium complex) to the inner springs (1), outer springs (2), and to the inner (3) and outer (4) surfaces of the cam pins.

4. Orient the hub with the offset outer end (1) upward, as shown. Choose a linear starting row (A) from which the first set of springs and cam pin (2) will be inserted for each radial row. Mark this start point. Choose a clockwise (B) or counterclockwise direction that the consecutive springs and pin configurations will be inserted repeatedly for each radial row. Reference the last or third row of the chart or method that was used to record the distribution of the inner springs. Assemble the spring(s) configuration into the cam pin. Insert the spring(s) and pin into the designated starting pocket (2) of the hub (1) one position at a time. Ensure the cam pin contact surface of each linear row of pins is in straight alignment with each linear row (A). Repeat the procedure for each cam pin pocket position in this radial row only. Do not install all 24 cam pins at this time.

5. Slide the 102 mm (4.0 in) hose clamp (1) over the pins (2) covering one-half of the pin diameter. Ensure the clamp is covering all pins equally, and then tighten the clamp adjustment screw (3) until the cam pins are almost fully compressed into the hub. Ensure each of the contact surface of the pin is in straight alignment with the linear row (A).

83074992

83074989

6. Position the clutch housing (1) vertically with the opening upward clamped in a vise or on a stable work surface. Position the hub with the installed last row of pins into the housing opening and the pins aligned with the housing cam slots. Tighten the hose clamp adjustment screw to ensure the pins are compressed into the hub creating a gap (2) between the pin and the housing (3). Ensure all pins will not contact the housing outer edge. Ensure the hub is vertical in the housing and not canted to one side.

NOTICE: The hardened metal properties of the clutch housing outer edge can shave the new edges of the cam pins, when the hub is driven into the housing, thus ruining the performance characteristics of the clutch and potentially contaminating the lubricant with metallic shavings. 7. Using a soft face dead blow mallet, drive the hub (1) slowly into the housing, ensuring the pins are not contacting the edges of the housing, until the pins are released from the hose clamp (2) and snap into their respective cam slots of the housing. Remove the hose clamp and adjust the diameter in order to fit over the next row of pins. Repeat the procedure for each consecutive row of pins. Ensure the spring distribution chart is followed and that the first set of spring(s) and cam pin always starts at the marked starting point of the hub. Reference: Step 4, Figure 5. 8. When the three rows of the cam pins have been installed into the clutch housing, drive the hub into the housing until seated at the bottom of the housing. Inspection of the opposite end of the housing will verify complete insertion of the hub.
