All 82 pages of this International 946, 1046, 1246 Operator Manual (OEM #1090743R3) put the factory's own operating playbook in your hands, covering the diesel tractor's instrument panel, three-point hitch, drawbar, draft and position control, and front loader setup. Inside you get wiring diagrams, a complete safety section, and a maintenance chapter that runs from filter and oil service through the fuel injection and cooling systems. The controls chapter walks you through every gauge and lever before your first field run, and the attachments section spells out setup for each implement. PTO clutch lever free travel checks at 40-50 mm (1.6-2.0 in.); front wheel bolts torque to 15-18 daNm (110-130 ft lbs). Your machine shouldn't be sitting idle while you hunt through forum posts for a basic adjustment spec. Bookmarked for instant navigation. Grab it on your tablet and start wrenching.

International 946, 1046, 1246 Common Problems This Manual Covers
International 1246 engine overheating with steam from the exhaust during heavy field operation p. 74
Inspect the cooling system using the troubleshooting guide on page 74. Clean the clogged radiator air passages and verify the fan belt is tight. Check the fuel injection pressure, ensuring it stays between 201-209 bar (2915-3030 PSI), as improper delivery creates excess engine heat.
Manual Section: Engine OverheatsTransmission slipping and engine clutch pedal feels completely spongy when shifting gears p. 63
Measure the engine clutch pedal free travel using the calibration procedures on page 63. Adjust the linkage until you achieve a free travel of 30-40 mm (1.2-1.6 in.). If the pedal still feels spongy, inspect the hydraulic system for air bubbles and verify fluid levels.
Manual Section: MaintenancePTO hand lever failing to engage implements or stalling the engine under heavy load p. 63
Verify the hand lever free travel at the top measures 40-50 mm (1.6-2.0 in.) as shown on page 63. Adjust the mechanical linkage immediately if clutch lining wear causes the play to drop to 10 mm (.4 in.) or less to prevent continuous slippage.
Manual Section: MaintenanceFront wheels wobbling or steering wandering side to side on paved roads p. 19
Check the front wheel tire pressure on page 19 and inflate to 2.0 kg/cm² (28 PSI) for on-road transport. Inspect the front wheel bolts and tighten them to the specified 15-18 daNm (110-130 ft lbs) torque rating found on page 16 to secure the rim.
Manual Section: Introduction and Technical DataFrequently Asked Questions
What is the engine capacity and displacement of the International 946, 1046, and 1246 tractors?
The International 946 tractor has a piston displacement of 5073 cm³ (310 cu in). The International 1046 and 1246 tractors both have a piston displacement of 5867 cm³ (358 cu in).
What are the transmission gear configurations for the International 946, 1046, and 1246?
The transmission gear configurations are detailed by travelling speeds across Creep, Normal, and Reverse ranges, with 6 gears in Normal and 2 in Creep. For example, the 946 tractor (25 kmph version) in Normal (H) range, gear 1, travels at 1.2 kmph (0.75 mph). The speed range lever allows selection of Hare (Hi), Tortoise (Lo), and Reverse ranges.
What are the replacement specifications for Clutch disc assembly?
The clutch is a dual plate, dry disk, spring loaded type. For the 946/1046 models, the engine clutch disk is 280 mm (11 in) and the PTO clutch disk is 295 mm (11.6 in). For the 1246 model, both the engine and PTO clutch disks are 310 mm (12.2 in).
How do you fix international 1246 engine overheating with steam from the exhaust during heavy field operation?
