Approximately 2.5 - 2.7 Liters (specific variant dependent)
Horsepower Drawbar:
Estimated 30-35 HP (Drawbar)
Horsepower Belt:
Estimated 35-40 HP (Belt)
Injection System:
Typically CAV or similar indirect injection system.
Oil Type:
Refer to manual for specific SAE viscosity grades (e.g., SAE 30, 10W-30) and API classifications for diesel engines of the era.
Type:
Variable speed governor for engine RPM control.
Type:
Manual Sliding Gear Transmission
Speeds:
Typically 8 forward and 2 reverse speeds (e.g., 4 ranges x 2 gears per range).
Power Take Off:
Standard PTO with multiple speeds (e.g., 540 RPM).
Differential Lock:
Yes, mechanical engagement.
Clutch:
Single dry plate clutch.
Wheelbase:
Varies by configuration, typically around 70-80 inches.

Approximately 3,500 - 4,000 lbs (1588 - 1814 kg).
Size:
Commonly 11.2-28 or 12.4-28
Rollover Protection:
ROPS (Rollover Protective Structure) not standard on original production; often a dealer or aftermarket fitment. Manual would cover installation and maintenance of such structures if provided.
Braking System:
Mechanical drum brakes (rear wheels), external contracting type for park brake.
Operator Station:
Open operator station, with hand controls and foot pedals.
Features:
Basic instrumentation: Ammeter, oil pressure gauge, temperature gauge, tachometer (engine RPM).
Features:
None in the modern sense. Basic safety features include brakes and lighting.
Features:
No electronic connectivity or communication features.
Engine Oil Change:
Typically every 100-200 operating hours or annually, depending on usage and oil specifications.
Fuel Filter Change:
As recommended, often with oil changes or when issues arise.
Air Filter Service:
Check and clean frequently, replace as needed, especially in dusty conditions.
Coolant Change:
Typically every 1-2 years to maintain anti-corrosion properties.
Engine Oil Capacity:
Refer to manual, typically around 5-6 quarts (4.7-5.7 liters).
Transmission Hydraulic Fluid:
Specific IH Hy-Trans or equivalent multi-purpose tractor fluid required for transmission, differential, and hydraulic system.
Coolant Type:
Ethylene glycol based antifreeze with corrosion inhibitors, mixed with distilled water.
Engine:
Potential for injector pump wear, exhaust leaks, and glow plug reliability (depending on starting system). Oil leaks at seals and gaskets are common with age.
Transmission Hydraulic:
Hydraulic lift issues (slow operation, loss of power) due to worn pumps or cylinders, or fluid contamination. Clutch wear and PTO engagement problems.
Electrical:
Wiring harness degradation, starter/generator issues due to age and wear.
Cooling System:
Radiator core degradation, thermostat sticking, and water pump seal leaks.
Manufacturer:
International Harvester (IH), a major American manufacturer of agricultural and construction machinery.
Predecessors:
Part of IH's lineage of utility tractors, evolving from earlier models like the Super A, Cub, and B-series.
