Part of the New Holland Repair Manuals.
This 590-page New Holland TK65-TK95 Series Repair Manual (OEM #86637917) covers the full Crawler Tractor lineup: TK65-TK95 Series. Inside, you get complete engine, clutch, and transmission procedures, rear mechanical wheel drive and mechanical PTO breakdowns, plus a dedicated braking, lift, and steering clutches section. The suspension and tracks chapter runs alongside a full electrical system section with wiring diagrams for every model in the lineup, so you're not stuck backtracking a harness with a test light and a hope. Set the braking unit hydraulic actuator pressure between 27 and 29 bar (391 to 420 psi), and fill the cooling system to 13.0 dm3 on your TK76, TK85, or TK95 (10.5 dm3 on the TK65/TK75). Stop guessing which sump capacity applies to your track loader. Bookmarked by section, this PDF opens on your phone or tablet so you can search any spec and get straight back to the tracks.

New Holland TK65–TK95 Series Common Problems This Manual Covers
New Holland TK85M engine cranks but won't start, produces heavy black smoke in cold weather
Check the engine troubleshooting chart for no-start conditions. Verify valve-rocker arm clearance is set to 0.30 ± 0.05 mm (0.1654 ± 0.0276 in.) with the engine cold; tight clearance kills compression and causes hard starting. Bleed air from the fuel system, inspect the cold start device, and confirm battery voltage reads above 12.4V before condemning the starter.
Manual Section: Engine TroubleshootingClutch slips under heavy load and jerks abruptly when engaging on hills
Inspect the main clutch driven plate for glazing or oil contamination. Measure friction lining thickness with a caliper and replace the plate if it falls below 9.7 to 10.3 mm (0.3819 to 0.4055 in.). Adjust pedal free travel to spec, check the release bearing for wear, and verify the pressure plate springs seat evenly.
Manual Section: Clutch TroubleshootingPTO loses speed and slips under heavy load, hard to select PTO range
Remove the PTO clutch cover and inspect the driven plate. Replace it once thickness drops below 7.3 to 7.9 mm (0.2874 to 0.3110 in.) measured under a 7500 N load. Check clutch pack spring pressure, verify the selector linkage adjustment at the control lever, and confirm the PTO housing oil level meets spec.
Manual Section: Mechanical Power Take-Off (PTO) TroubleshootingBrakes feel spongy and tractor pulls hard to one side when stopping suddenly
Bleed the hydraulic braking circuit fully before testing. Connect a gauge to the braking unit hydraulic actuator and confirm it reads 27 to 29 bar (391 to 420 psi) as specified on page 296. Adjust the balance linkage between left and right brake pedals, inspect friction discs for uneven wear, and top off brake fluid to the correct level.
Manual Section: Braking System Troubleshooting p. 296Steering clutch sticks and drags, tractor pulls to one side during sharp turns
Remove the steering clutch access cover and inspect the friction plates for glazing or contamination. Torque the internal drum locknut to 343 Nm (35 kgm) as specified on page 357. Check release linkage travel on both sides, clean any sludge from the clutch drum, and confirm return spring tension is equal left to right.
Manual Section: Steering Clutches Troubleshooting p. 357Starter motor cranks slowly or fails to engage in cold weather conditions
Test the starting circuit for excessive voltage drop at every connection using a multimeter, then measure current draw at the starter motor and compare it against the rated absorption value. Clean and tighten both battery terminals, check the ground strap for continuity, and confirm the battery holds full state of charge before replacing the starter.
