Part of the New Holland Repair Manuals.
Six tractors, one book: this 778-page New Holland TD5 Service Manual (OEM #48012878) covers the TD5.65, TD5.75, TD5.80, TD5.90, TD5.100, and TD5.110 from clutch to cab. You get full wiring diagrams for the harness and connector layout, hydraulic schematics for the main and auxiliary valve circuits, and a troubleshooting section that walks you through transmission, steering, and hydraulic lift complaints instead of leaving you guessing. Exploded views back up every axle, gearbox, and final drive teardown, and the torque tables sit right next to the procedures that need them. The VALEO main clutch driven plate should read 10.2 to 10.8 mm before you button it back up; that's the kind of number forums get wrong. Your machine is down and every hour on the clock costs you money. Bookmarked by system, so you jump straight to Transmission or Electrical Systems and get back to the shop floor fast.

New Holland TD5.65–TD5.110 Series Common Problems This Manual Covers
New Holland TD5 hydraulic lift response turns sluggish after 300 service hours, arms lift slowly
Check the suction-side paper cartridge filter fixed to the pump housing (page 405); remove it and clean or replace if clogged. Test pump bench output, a worn pump falls to 22300.01 cm³/turn versus 24800.02 cm³/turn new after 300 hours (page 406). Verify the relief valve holds 186-191 bar (page 449) before returning the tractor to service.
Manual Section: Hydraulic Systems p. 405Clutch slippage or failure to fully engage, driven plate wear suspected
Remove the clutch cover and measure driven plate thickness with a caliper. Main clutch plates from VALEO or LUK must read 10.2-10.8 mm (page 50); replace any plate measuring under 10.2 mm. Torque the clutch/flywheel retaining bolts to 59 N·m on TD5.90, TD5.100, and TD5.110 during reassembly (page 51). Check PTO clutch plates too, spec is 7.3-7.9 mm.
Manual Section: Clutch p. 50PTO drive stutters under load with support bushing noise at the driven gear
Pull the PTO driven gear and measure the external diameter of the driven gear support bushings with a micrometer. Spec calls for 49.925-49.950 mm (page 324); replace the bushing if it reads undersize or scored. While the box is open, torque the PTO box fixing screws to 221 N·m (page 325), since fatigue loosening is a common repeat-failure cause here.
Manual Section: Power Take-Off (PTO) p. 324Battery voltage drops below 12 V under load or won't hold a charge overnight
Test electrolyte relative density with a hydrometer; fully charged cells should read 1.280 at 25°C (page 695). Clean and re-torque the ground point connection (page 613), since corrosion there mimics a dead battery. Charge the battery fully and retest under load; if any cell stays below 1.280 after charging, replace the battery.
Manual Section: Electrical Systems p. 695Frequently Asked Questions
What are the torque specifications for the clutch components on New Holland TD5.110 models?
For TD5.110 models, the clutch/flywheel retaining bolts (M10 X 1.25) should be tightened to 59 N·m (43.5162 lb ft). The retaining bolts securing the clutch casing to the engine (M12 X 1.25) require a torque of 98 N·m (72.2811 lb ft). p. 51
What are the torque specifications for various axle bolts on New Holland TD5.80 models?
For TD5.80 models, the lock ring for the bevel pinion (M35 X 15) should be tightened to 294 N·m (216.84 lb ft). The front axle front and rear pivot support bolt (C₉) (M18 X 1.5) requires a torque of 392 N·m (289.12 lb ft). p. 205
What are the replacement specifications for the suction-side hydraulic filter?
The suction-side hydraulic filter is a paper cartridge type, fixed to the pump housing. The manual does not provide specific replacement intervals or part numbers for this filter. p. 405
What are the thickness specifications for the main clutch and PTO clutch driven plates for TD5.65, TD5.75, and TD5.80 models?
For TD5.65, TD5.75, and TD5.80 models, the main clutch driven plate (VALEO Organic agglomerate and cerametallic) should have a thickness of 10.2 – 10.8 mm (0.4016 – 0.4252 in). The PTO clutch driven plate (VALEO) should be 7.3 – 7.9 mm (0.2874 – 0.3110 in) thick. p. 50
