Part of the New Holland Repair Manuals.
This 712-page New Holland TC29D, TC33D Repair Manual (OEM #87036760) covers both compact tractors nose to tail, from the diesel engine overhaul down to the last dash console screw. You get full wiring diagrams for the electrical system, hydraulic schematics covering the control valve and remote spool circuits, and a dedicated troubleshooting section for the hydrostatic transmission when your TC29D won't shift right. Inside you'll also find exploded views for the FWD axle and PTO gearbox, plus torque tables covering everything from cylinder head bolts to wheel nuts. The radiator cap holds 0.9 bar (13 PSI), and the thermostat starts opening at 71°C (160°F), real factory numbers, not a forum guess. No more pulling panels blind trying to trace a short. Bookmarked by system, so you jump straight from cover to hydrostatic overhaul without hunting through 700 pages on your phone in the shop.

New Holland TC29D, TC33D Common Problems This Manual Covers
Hydraulic fluid overheating and turning dark after short work sessions
Drain and inspect the hydraulic fluid for contamination or a burnt smell; discoloration this fast points to internal pump wear generating heat. Measure rotor-to-vane clearance against the 0.01-0.15 mm (0.004-0.006 inch) standard on page 95, replacing the pump if clearance exceeds 0.25 mm (0.010 inch); worn vanes or rotor scoring beyond this limit require pump replacement.
p. 449Frequently Asked Questions
What are the torque specs for New Holland TC29D head bolts?
For the New Holland TC29D, the head bolts should be torqued to 88 - 94 N⋅m (65.1 - 68.7 ft lbs). This specification is crucial for proper engine assembly and performance. p. 121
How do you fix new Holland TC33D clutch slipping under load after 500 hours, tractor bogs down on hills?
Check clutch pedal free-travel first; it should measure 19 mm to 30 mm (0.79-1.18 inches) per page 167. If travel is out of spec, adjust the linkage. If travel is correct but slipping persists, the clutch disc has likely worn past its limit and needs replacement. p. 166
How do you fix engine overheating during operation in hot weather, temp gauge climbing at idle?
Check coolant level first and top off if low. Inspect the thermostat; it should start opening at 71°C (160°F) and be fully open by 85°C (185°F) per page 34. Test the radiator cap for a 0.9 bar (13 PSI) seal on page 121, and check V-belt deflection at 10-15 mm under 9-11 kg thumb pressure. Backflush the cooling system if rust or scale is clogging water ports. p. 112
How do you fix hydraulic system won't lift implement or lifts very slowly at low engine RPM?
Verify the external and internal lift linkage is properly adjusted; misadjustment is the most common cause of a no-lift condition. If lift is slow rather than absent, clean or replace the suction filter screen. Confirm pump output meets 29.0 L/min (7.6 GPM) rated capacity on page 453, and check the system relief valve is holding at 145 ± 5 bar (2133 ± 70 psi). p. 448
