New Holland TM120, TM130, TM140, TM155, TM175, TM190 Tractor Pdf Repair Service Manual (P. Nb. 87611238)

New Holland TM120, TM130, TM140, TM155, TM175 & TM190 Tractor PDF Repair Service Manual (Publication No. 87611238)

When the workday involves pulling wide cultivators, operating high-capacity seed drills, powering forage equipment and transporting heavy trailers between fields, a tractor must deliver dependable performance hour after hour. The New Holland TM120, TM130, TM140, TM155, TM175 and TM190 were developed for professional farming operations where power, hydraulic performance and operator comfort are equally important. As these tractors accumulate thousands of field hours, components such as the powershift transmission, front axle, PTO and hydraulic system require accurate diagnosis and professional repair.

This OEM Factory Repair Service Manual (Publication No. 87611238) provides the same technical workshop procedures used by New Holland dealership technicians to restore these machines to factory operating standards. It covers complete repair, overhaul, testing and adjustment procedures for every major tractor system.

Instead of simply listing maintenance intervals, this workshop manual explains why components fail under heavy agricultural workloads and how to diagnose the real cause before replacing expensive parts. Whether you're rebuilding a transmission, servicing the hydraulic system or troubleshooting electrical faults, every repair follows the structured workflow recommended by the manufacturer.

Engineered for Large-Scale Agricultural Operations

The TM Series became a popular choice among grain producers, mixed farms and agricultural contractors because it combines high engine output with versatile field performance. Depending on the model, these tractors deliver approximately 120–190 engine horsepower and are equipped with heavy-duty powershift transmission options, high-capacity hydraulic systems and mechanical front-wheel drive for maximum traction. Their strong rear linkage and independent PTO allow them to handle demanding implements including large ploughs, air seeders, balers, slurry tankers and grain carts throughout the farming season.

Machine Information

Designed Around Real Workshop Fault Diagnosis

On high-horsepower tractors, a single warning light can originate from several interconnected systems. A transmission complaint may actually be caused by hydraulic pressure loss, while poor lifting performance could result from an electronic control issue rather than a worn pump. This repair manual follows the same diagnostic sequence used by dealership technicians, helping workshops isolate faults efficiently while avoiding unnecessary component replacement.

• Calibrate the powershift transmission after clutch or gearbox repairs.
• Measure hydraulic pressure before replacing pumps or remote control valves.
• Inspect the MFWD front axle, hubs and differential after heavy draft applications.
• Repair independent PTO assemblies used with balers, forage harvesters and slurry equipment.
• Diagnose rear linkage performance using factory hydraulic testing procedures.
• Overhaul steering components to restore precise field handling.
• Trace charging, starting and electronic control faults with complete OEM wiring diagrams.
• Service brake components for safe transport between fields and road travel.
• Inspect driveline couplings and rear axle assemblies after prolonged heavy towing.
• Confirm factory tolerances, torque values and adjustment specifications before final assembly.
