• Stop the engine and relieve pressure before connecting disconnecting
• T ighten all connections before starting the engine pressurizing not modify permit anyone else modify alter this tractor any its components functions without first consulting a NEW HOLLAND Dealer
The fuel oil the injection system under high pressure and can penetrate the skin. Unqualified persons should not remove attempt adjust a injector , any other part the fuel injection Failure follow these instructions can result serious injury
Continuous long - term contact with used engine oil may cause skin cancer A void prolonged contact with used engine ash skin promptly with soap and water
Some components your tractor , such gaskets and friction surfaces (brake clutch may contain Breathing asbestos dust dangerous your Y are advised have any maintenance repair such components carried out authorized NEW HOLLAND Dealer . However , service operations are undertaken parts that contain the essential precautions listed below must observed:
• W ork out doors a well ventilated

Basic instructions Hardware
General
The WORKMASTER tractor has been built using metric

Certain hardware must tightened specific torque specific torque specifications are not tighten the hardware the standard torque chart specification listed this manual.
Plating
Hardware used New Holland balers plated with zinc chromate (gold color). Gold colored hardware has dif ferent torquing requirements from unplated zinc plated (silver color) hardware because the dif ference the coef ficient friction the plating The torque charts this manual list the correct specifications for silver , and unplated
Nut T ightening
Whenever the nut should not the head the When tightening using the bolt the clamp load can lost because some the torque applied twists the bolt instead tensioning (stretching) The tension the bolt what holds the joint together .
Approximately 90% the torque applied during assembly goes overcoming friction between the The other 10% used tension (stretch) the bolt. After assembly , the frictional forces disappear , which the basis for the saying ’If does not fail during assembly , will not fail service.’ The bolt may later fail due other but not from being over
Locknuts
Most locknuts are coated with a special lubricant that dry the Anytime a locknut a lower than normal torque Refer the torque charts this manual for specific
Jam Nuts

Clamping Force - Force equal the tension the fastener that clamps the parts together
Stabilized T orque - T orque measured a joint that has had a settling time after fastener and the torque measured the direction the moment after the bolt / nut begins
Proof Load - Safe test load for approximately 10% below the yield

T orque Y ield - Bolting method that tightens the joint until yield Generally requires a computer monitored tightening
T arget T orque - T orque specified engineering, generally nominal torque.
Ultimate Load - Load when bolt failure
Y ield Load - Load when deformation
NOTE: Fasteners should replaced with the same higher grade. higher grade fasteners are used, these should only tightened the strength the original. When replacing cap screws, always use a cap screw the same measurement and strength the cap screw being replaced.
NOTE: Make sure the fasteners threads are clean, and that thread engagement started. This will prevent them from failing when being tightened. Assure that joints that utilize threaded fasteners are properly tightened, and that they remain tight during the period their intended usage.
NOTE: T ighten plastic insert crimped steel - type lock nuts approximately % table torque, applied the nut, not the bolt head. T ighten toothed serrated type lock nuts their full torque value.
NOTE: Always use the torque values listed the supplied charts this section when values are not supplied a procedure.
NOTE: NOT use these torque values when values are given a specified procedure.
NOTE: Reuse fasteners. Fasteners that have been tightened above yield point during assembly should not reused after disassembly . They have been permanently deformed and the elastic range has been shifted closer the ultimate tensile point.
NOTE: T orque and T urn a recommended procedure for manufacturing and service when sophisticated tools are not available, especially for large diameter fasteners.
NOTE: Large diameter fasteners, unless specifically stated, should tightened sequence using the related torque chart below , a low torque that sufficient until the joint closed. Each bolt then rotated degrees sequence. Each bolt then rotated another degrees sequence. The result a clamp load above the yield point. This procedure results a consistent clamp load. The fasteners should not reused after disassembly . df5019 - 1 1
NOTE: Shown above the suggested initial torque tightening sequences for general tighten sequence from item 1 through the last item hardware.
Hydraulic Hoses and T ubes
NOTE: T ightening the joint the proper torque will keep leak free, and prevent from damaging the hose fitting. Always replace hoses and tubes with damaged cone ends the end When installing a new hose, loosely connect each end and make sure the hose fits its desired location, without kinking before tightening the T ighten non - swivel end hose first T ighten the hose clamps enough hold the hose without chafing but not tight crush the Keep the hoses and tubes clear moving parts and replace any hoses and fittings that have moved from their original positions over A hose with a chafed outer cover will allow moisture get into the Concealed corrosion the wire reinforcement will then occur along the hose length and result hose Ballooning the hose indicates internal leakage the hose This condition can rapidly lead hose
Kinked, crushed, stretched damaged hoses generally suf fer internal structural damage that restricts fluid flow , duces performance and ultimately causes the hose not allow free unsupported hoses tubes touch each other related working This causes chafing and reduces line
National Pipe Thread (NPT) Fittings
Before installing and tightening pipe clean the threads with a cleaning solvent Loctite® brand cleaner Apply the appropriate Loctite® brand sealant all fittings including stainless unless otherwise Generally Loctite® 567™ can used for all fittings including stainless steel. Loctite® 565™ used for most metal fittings. For high filtration / zero contamination systems use Loctite® 545™.
