Need the New Holland TB110 repair manual as a PDF? This 678-page factory manual (OEM #87046217) covers the TB100, TB110, TB120, and TB120 Mudder tractors from clutch to final drive. Open it up and you get complete engine strip-down procedures, transmission overhaul steps, and a full electrical section with wire harness routing and component locations. Hydraulic schematics walk you through the tandem pump and steering circuit, while the fault finding charts cover engine, hydraulic, and electrical faults side by side. Set fuel injector clearance and torque per the specs table, and follow the documented break-in procedure for both low-hp and standard applications before you hand the tractor back. No more flipping through a stack of loose sheets looking for one torque value. Every section is bookmarked, so you jump straight from engine to steering to electrical without scrolling. Pull it up on your phone in the shop and get back under the hood.

New Holland TB100, TB110, TB120, TB120 Mudder Common Problems This Manual Covers
New Holland TB110 hydraulic pressure drops after 200+ hours, loader and brakes feel slow to respond
Check hydraulic oil operating temperature stays within 57-63°C on page 415; oil running hotter than that points to fluid bypassing worn pump seals. Pull the suction line and clean the strainer screen. Reseat the pressure relief valve and torque it to 60-68 Nm per page 416, then bleed the circuit and recheck lift response under load.
Manual Section: Hydraulic System Fault Finding p. 418Engine stalls under load or overheats during heavy mowing despite a clean coolant system
Pull the thermostat and confirm it opens at 79-83°C and reaches fully open by 93-96°C per page 140; a stuck-closed thermostat starves flow long before the gauge shows trouble. Reinstall with the housing bolts torqued to 24 Nm. Work the fault finding chart on page 64 next to rule out injector timing or a restricted air intake as the load-stall cause.
Manual Section: Engine General Fault Finding p. 64Transmission slips or hesitates shifting under load, worse in wet field conditions
Hook a gauge to the dual command circuit and verify system pressure reads 15.2-18 bar per page 252; anything below that means the clutch pack is losing hold under load. Drain and check the fill against the 56 liter transmission oil capacity on page 226, since a low or contaminated charge will mimic worn clutch symptoms.
Manual Section: Transmission Dual Command Fault Finding p. 252Front axle grinds or vibrates abnormally during sharp turns
Drain and refill the front axle differential to its 6 liter capacity spec on page 301, checking the drained oil for metal fines that confirm bearing wear. Inspect the steering cylinder end-plate bolts and torque them to 120 Nm per page 301 if they've backed off, since a loose end-plate lets the cylinder rock and telegraphs as axle grind on tight turns.
Manual Section: Front Axle--Four Wheel Drive p. 301Clutch pedal engages roughly or gears are hard to select even with the pedal fully depressed
Measure clutch pedal free play; it should fall between 19 and 25.4 mm per page 214. Free play outside that range means the release bearing isn't fully disengaging the pressure plate. Back off the adjuster nut, reset the play within spec, and cycle the pedal several times to confirm the bearing releases cleanly before road testing gear selection.
Manual Section: Clutch System Fault Finding p. 214Frequently Asked Questions
What are the replacement specifications for the clutch assembly and release bearing?
The diaphragm type clutch has no serviceable components, so a new assembly is required if faults are discovered. The clutch disc assembly is a 14in (355.6 mm) Single Disc Dry Plate made of Cerametalic. Replace the friction disc if there are signs of overheating or excessive wear, and replace the release bearing if the hub does not move freely, does not rotate smoothly, or shows damage/wear. p. 214
What is the engine oil capacity for 4-cylinder and 6-cylinder engines?
The engine oil capacity with the oil filter is 11.4 liters (3.0 U.S. Gals) for 4-cylinder engines and 19 liters (5.0 U.S. Gals) for 6-cylinder engines. p. 58
What is the tightening sequence and torque for the cylinder head bolts?
The cylinder head bolts should be tightened progressively in three stages: Stage 1 to 156 N⋅m (115 ft.-lb.), Stage 2 to 190 N⋅m (140 ft.-lb.), and Stage 3 to 217 N⋅m (160 ft.-lb.). Ensure bolts are lubricated before assembly and torqued when the engine is cold. p. 95
What are the valve lash settings for intake and exhaust valves?
The intake valve lash should be set to 0.36-0.46 mm (0.014-0.018 in.) and the exhaust valve lash to 0.43-0.53 mm (0.017-0.021 in.). These settings must be adjusted only when the engine is cold. p. 95
