![New Holland G110.2 G110.2 6WD Tier 2 Repair Manual [Grader]](https://youfixthis.com/wp-content/uploads/2012/02/Manual_Download-300x300.jpg)
Part of the New Holland Repair Manuals.
The TV140 is a strange animal - a bidirectional tractor with a cab that swivels, an axle at each end, and a PTO at each end too. Generic tractor manuals are useless on it. This 9-volume factory set covers the whole machine: the 7472 cc six-cylinder turbo engine (147 hp, firing order 1-5-3-6-2-4), the hydrostatic drive and splitter box, both the engine-end and cab-end axles and hitches, both PTOs, brakes, the R134a climate system, and the full electrical package. You get EICS error code listings, complete wiring diagrams, pressure test procedures with actual specs, and two-stage torque tables. If you own a TV140 and turn your own wrenches, this is the book the dealer techs used.

New Holland TV140 Common Problems This Manual Covers
Tractor suddenly dies and stays dead until you lift the cab, then runs fine again.
Classic TV140 complaint - a vibration-chafed or corroded connector under the cab. Use the complete wiring diagrams beginning at p.2025 and the circuit isolation schematics in the Electrical System section to trace the power and ground paths under the cab instead of wiggle-testing blind.
Manual Section: Electrical System - Section 55 p. 1704Hard starting or no-start after a fuel filter change or running out of fuel.
Air trapped in the fuel system will keep this engine from firing no matter how long you crank. The Fuel System coverage in Engine Systems gives the bleeding procedure on p.261 - do it before you condemn the injection pump or the starter.
Manual Section: Engine Systems - Fuel System p. 261Weak, slow, or jerky hydraulics on the hitch or remotes.
Start with oil level and the suction filter, then put a gauge on it. The Hydraulic Systems pressure testing procedures let you check the implement pump against its 197 bar rated pressure (p.885) and the flow compensator setting, separating a tired pump from aerated oil or a valve problem.
Manual Section: Hydraulic Systems - Pressure Testing p. 1015Driveline vibration, clunking, or abnormal noise underneath the machine.
The bidirectional layout runs long drivelines with U-joints that wear and get ignored. The Transmissions section covers driveline inspection and overhaul along with the splitter box and hydrostatic drive, so you can isolate a worn joint or bearing before it takes out something expensive.
Manual Section: Transmissions - Drivelines p. 302Frequently Asked Questions
How do I troubleshoot a New Holland TV140 that won't start?
Work it in order: battery charge and clean terminals, then grounds, then the starter circuit through the fuse and relay panel covered in the Electrical System section. If it cranks but won't fire, suspect air in the fuel system - the manual walks you through bleeding it on p.261, which is often all a TV140 needs after a filter change or running the tank dry. The starting and charging system tests tell you whether it's the starter, solenoid, or wiring before you buy parts. p. 261
What do the New Holland TV140 error codes mean?
The TV140 uses the EICS instrument cluster system, and the manual lists and explains the EICS error codes starting at p.2006 in Section 55. Each code points you to the circuit at fault, and the circuit isolation schematics let you chase it wire by wire instead of guessing. This is a printed-code era machine - no laptop or dealer scan tool needed, just the code list and a multimeter. p. 2006
What are the torque specs for a New Holland TV140?
The manual includes both standard torque data in the General Information section and machine-specific tables where it matters. The engine torque table on p.84 gives figures like the camshaft gear bolt at 69 N-m and the two-stage main bearing bolts at 81 N-m plus 90 degrees. Two-stage torques are printed as two stages - follow them that way, especially on the bottom end. p. 84
What is the hydraulic pressure spec for a New Holland TV140?
Implement pump rated pressure is 197 bar (2857 PSI), covered on p.885, with a maximum dead-head of 214 bar (3100 PSI) and low pressure standby at 19 plus or minus 1.7 bar (275 plus or minus 25 PSI). For the hydrostatic drive, the charge pressure test range is 1.6 to 3.4 bar, p.1015. The Hydraulic Systems section gives the full pressure testing procedure, including where to tee in your gauge. p. 885
How do I clear fault codes on a New Holland TV140?
On the EICS system, a code that keeps coming back means the fault is still there - it is not a reset problem. Look the code up on p.2006, test the circuit with the isolation schematics in the Electrical System section, and fix the cause. Owners who top up fluid or swap a filter and still see the warning light usually have a sensor fault or a real low-pressure condition underneath, and the troubleshooting charts sort those apart. p. 2006
