Engine Displacement Range:
Ranges from approximately 179 cubic inches (D-179) to 282 cubic inches (BD-282).
Typical Horsepower Range:
Approximately 45-75 PTO horsepower depending on specific model and engine variant.
Injection System:
Various rotary or inline injection pumps (e.g., CAV, Bosch) depending on engine variant.
Transmission Type:
Constant mesh, sliding gear transmission with multiple forward and reverse gears (e.g., 8-speed, 16-speed with high/low range).
Optional Transmission:
Some models may have offered a synchronized transmission or a torque amplifier (TA) option for increased gear ratios.
Pto Type:
540/1000 RPM PTO, depending on model and configuration.
Dashboard:
Basic instrumentation including tachometer, engine temperature gauge, oil pressure gauge, and battery charge indicator.
Governor:
Mechanical engine governor for maintaining engine speed under varying loads.
Lighting System:
Standard 12-volt electrical system with headlights, taillights, and work lights depending on configuration.
Engine Oil Change:
Typically every 100-250 operating hours, or annually, depending on operating conditions and oil type used.
Hydraulic Fluid Change:
Recommended every 500-1000 operating hours or as specified by IH, with filter changes more frequently.
Transmission Fluid Change:
Varies greatly by transmission type; consult the manual for specific intervals.
Engine Oil Grade:
API Service Classification CD or CE, SAE 30 or 10W-30 depending on ambient temperature (e.g., IH Hy-Tran Plus or equivalent).
Hydraulic Fluid Type:
IH Hy-Tran (or equivalent universal tractor transmission fluid - UTF) is critical for proper operation of the hydraulics and transmission.
Coolant Type:
Ethylene glycol based antifreeze with corrosion inhibitors, typically a 50/50 mix with distilled water.
Transmission Fluid Type:
Specific IH Hy-Tran or approved aftermarket UTF for most transmissions and hydraulic systems to ensure proper operation and prevent damage.
Common Problems:
Wear in the hydraulic pump and control valves, clutch wear, front axle kingpin wear, starter/alternator issues, and potential for fuel injection pump problems.
