Part of the New Holland Operator Manuals.
From cold-start procedure to SCR exhaust treatment to the 3600-hour coolant change, this New Holland T5.90, T5.100, T5.110 and T5.120 operator manual PDF walks all four tractors end to end under OEM number 51594058, in 366 pages. The maintenance chart runs nearly a quarter of the book, laying out service by the hour meter: daily engine oil checks, 50-hour hitch and 4WD axle greasing, 600-hour fuel filter changes. Fault code resolution gets its own section, so a flashing dashboard icon turns into a diagnosis instead of a call to your dealer. Torque the front wheel hubs to 215 N·m (159 lb ft) and the rears to 310 N·m (229 lb ft), straight from the factory tables. When a DEF fault trips, the SCR reset procedure on page 95 walks you through clearing it. Bookmarked and text-searchable, this PDF is yours after one download, for as long as you run the tractor.

New Holland T5.90, T5.100, T5.110, T5.120 Common Problems This Manual Covers
New Holland T5 tractor loses power under load, engine feels fuel starved partway through seeding
Replace the fuel filter first; hand tighten the new element 3/4 of a turn after gasket contact per page 282. Drain any water from the filter and check the 160.0 L tank level, since running low on slopes starves the pickup. Bleed the system, then follow the engine troubleshooting steps starting on page 325.
Manual Section: Engine troubleshooting p. 325Hydraulic lift raises slowly and the three-point hitch struggles to pick up heavier implements
Check the transmission and hydraulic oil level before anything else; the shared sump holds 63.0 L per page 252, and remote cylinders pull it down fast. Top up with the correct oil, then replace the lift oil filter, tightening the new element 3/4 of a turn per page 276, and retest lift speed loaded.
Manual Section: Hydraulic systems troubleshooting p. 252Battery charge warning light stays on or flickers when the engine is running
Check engine idle speed first: the book lists a low idle as the most common cause, and raising it often clears the light. Next check the alternator belt tensioner; a loose belt is the next listed cause. If the light stays on, test the battery (it should read at least 12.6 V) and check the electrolyte level and specific gravity. If none of that clears it, the fault is in the alternator itself (120 A standard, page 344), so have your dealer check it. Full electrical troubleshooting table on page 329.
Manual Section: Electrical system troubleshooting p. 329Engine cranks slowly on frosty mornings and will not fire until the third or fourth attempt
Verify battery charge and clean both terminals; the 4.2 kW starter draws heavy current, and a weak battery kills cranking speed in the cold. Fill with winter-grade diesel before the frost arrives, run the correct seasonal oil viscosity, and keep the engine oil changed on the 600 hour MAT3521 interval shown on page 250.
Manual Section: Engine troubleshooting p. 250Shuttle shift engages harshly and the tractor jerks when changing direction under light load
Run the transmission clutch calibration after any battery disconnect or clutch service. Warm the transmission oil, park on level ground, and set engine speed to 1300 +/- 50 RPM as the procedure on page 321 directs. If engagement stays rough after calibration, check the transmission oil level before losing a field day to a dealer visit.
Manual Section: Maintenance p. 321Frequently Asked Questions
How do I reset the service reminder on my New Holland T5 tractor?
To schedule maintenance on a New Holland T5 series tractor, enter the programming menu by pressing switch (2) on symbol (B) for more than three seconds. Press switch (3) on symbol (D) repeatedly until the display shows the maintenance frequency symbol (S1), then press switch (2) on symbol (B) to open it. Change the flashing digit with switch (2) on symbol (B), raise the value with switch (3) on symbol (C), and press switch (2) on symbol (B) again to save. Full steps are on pages 126 and 127. p. 126
What is the procedure for resetting the Selective Catalytic Reduction (SCR) system after a fault?
To fully reset the SCR system after a fault, the component or failure causing the fault must be repaired or replaced. Switching off the engine will reset the system and allow the engine to restart at full power. If the same failure is re-detected within 40 hours of engine operation, the maximum engine power loss level will be introduced. p. 95
What is the engine oil capacity for the New Holland T5.90–T5.120 tractors?
The engine oil capacity for the New Holland T5.90–T5.120 tractors is 9.5 L (2.5 US gal) when the filter is included, or 6.40 – 8.10 L (1.69 – 2.14 US gal) for the oil sump only. p. 252
What is the correct torque for the wheel hub nuts on the New Holland T5.90–T5.120?
The tightening torque for the front wheel hub nuts (M16) on the New Holland T5.90–T5.120 is 215 N·m (159 lb ft), and for the rear wheel hub nuts (M18) is 310 N·m (229 lb ft). p. 203
How often should the engine oil and filter be replaced?
The engine oil and filter should be replaced every 600 hours if using oil that meets the MAT3521 specification (NEW HOLLAND AMBRA UNITEK MASTERGOLD SBL CJ-4), every 500 hours for MAT3522 specification oil, or every 300 hours for other oils meeting API CJ-4 specifications. Always change annually if the hour interval is not reached. p. 250
