Running an International 955 or 1055 diesel tractor means staying on top of pre-shift checks, fluid levels, and scheduled intervals, and this 76-page Operator Manual (OEM #1 091 316 R3) is the factory document that tells you exactly how. Inside: a full instruments and controls section covering the PTO clutch lever, hydrostatic power steering, and instrument cluster, plus wiring diagrams for electrical fault tracing. You also get a complete maintenance chapter spanning the fuel system, cooling system, brake system, and transmission, alongside a dedicated trouble shooting section for engine and hydraulic draft control faults. Your transmission takes IH-Transmission oil to Spec. MIL-L-2105 GL 4; swap the primary fuel filter at the 800-hour mark and target 25 mm of free travel on the engine clutch. Every hour your tractor sits idle costs you. Download now: bookmarks take you straight to instruments, maintenance, or trouble shooting with one tap.

International 955, 1055, Diesel Tractors Common Problems This Manual Covers
International 955 1055 diesel engine won't start, cranks slowly, or runs rough at idle p. 73
Check the troubleshooting chart on page 73 for no-start and rough idle causes. Verify the fuel shutoff valve is fully open and the tank has adequate fuel. Inspect primary and secondary fuel filters; the primary filter is due every 800 operating hours (page 43). In cold weather, warm the engine at low idle before applying any load.
Manual Section: Trouble ShootingEngine shows premature wear after first week, overheats, or loses power under load p. 25
Follow the break-in instructions on page 25. During the first 20 operating hours, avoid sustained full throttle or heavy drawbar loads; vary the engine speed and allow it to cool between tasks. Check engine oil level every day using the daily inspection procedure on page 17 and watch for unusual consumption or smoke.
Manual Section: Operating the TractorWater in fuel system after leaving tank partially empty, engine misfires or stalls p. 17
Fill the fuel tank to the brim at the end of every working day. A full tank prevents overnight moisture condensation from introducing water into the system. Check and drain the water separator daily as part of the page 17 inspection. Replace the primary fuel filter every 800 operating hours (page 43) to keep injectors clean.
Manual Section: Preparing the Tractor for Each Day's WorkAfter rain or pressure washing, electrical system shorts out or tractor won't start p. 66
Check battery terminal connections for corrosion or looseness before each shift as part of the page 17 inspection. Verify electrolyte level is approximately 1 cm above the separators (page 66). The tractor uses a 12V, 110 Ah battery; avoid directing high-pressure water at the alternator, injection pump, or battery terminals during washing.
Manual Section: MaintenanceClutch pedal feels stiff, slips, or engages at the very top of travel p. 61
Check clutch pedal free travel; it should measure 25 mm (page 61). If it has worn to 10 mm or less, adjustment is overdue. Measure pedal height from the floor mat: the correct basic height is 155 mm. Inspect the clutch linkage for loose pivot pins or binding before putting the tractor back to work.
Manual Section: MaintenanceFrequently Asked Questions
What are the torque specs for the cylinder head bolts on an International 1055?
The torque specification for cylinder head bolts on an International 1055 is 14-15 daNm. This information is found in the 'Technical Data' section of the manual, which also advises referring to this section for torque values when retightening cylinder head bolts during maintenance.
What transmission and rear axle oil is recommended for the International 955?
For the transmission and rear axle of an International 955, the recommended gear oil is IH-Transmission oil. Use SAE 80 below -10°C and SAE 90 above -10°C, meeting IH-NeZG 4020 or MIL-L-2105 GL 4 spec.
How do I adjust the clutch pedal free travel on an International 955 or 1055 tractor?
The correct clutch pedal free travel on the International 955 and 1055 is 25 mm (page 61). If it wears to 10 mm or less, adjustment is required. The basic pedal height from the floor mat should be 155 mm. Inspect the clutch linkage for loose pivot pins or binding before returning the tractor to service.
What should I check first if my International 955 or 1055 diesel engine won't start?
If your International 955 or 1055 diesel engine won't start or runs rough, consult the troubleshooting chart on page 73. Verify the fuel shutoff valve is fully open and the tank has adequate fuel. Inspect primary and secondary fuel filters — the primary filter is due every 800 operating hours (page 43). In cold weather, warm the engine at low idle before applying any load.
