Engine Family:
IH/Case IH 4-cylinder Diesel Engines (e.g., 4.236, 4.318, 4.248 variations common in this era, specific engine variant depends on exact tractor model within the 85 series).
Horsepower Range:
Typically ranging from 50 to 85 PTO horsepower, depending on the specific model within the 85 Series (e.g., 685, 785, 885, 985).
Torque Characteristics:
Designed for robust, low-RPM torque delivery essential for heavy pulling and fieldwork. Specific figures vary by engine displacement.
Injection System:
Direct injection, typically with rotary or inline fuel injection pumps (e.g., CAV, Bosch).
Cooling Type:
Liquid-cooled, with radiator, fan, water pump, thermostat, and coolant reservoir.
Oil Type:
Diesel engine oil, typically API CF or CD specifications (e.g., SAE 15W-40). Refer to manual for exact specifications.
Common Displacements:
Approximately 3.9 Liters (236 cu in) to 4.3 Liters (264 cu in), depending on specific model variant.
Gearbox Type:
Synchronized constant mesh gearbox with multiple forward and reverse gears. Common configurations include 8 forward + 4 reverse, 12 forward + 4 reverse, or 16 forward + 8 reverse with creeper gears.
Powershift Option:
Optional Powershift or Torque Amplifier (TA) transmission for on-the-go gear changes or torque multiplication.
Pto Options:
Multiple PTO speeds, typically 540 RPM and 1000 RPM, and often ground speed PTO.
Clutch Type:
Dry single-stage or dual-stage clutch for transmission and PTO engagement.
Transmission Fluid:
Multi-purpose tractor lubricant (UTTO/THF) meeting Case IH specification, or equivalent. Refer to manual for exact fluid part numbers and specifications (e.g., Hy-Tran).
Engine Oil Change:
Typically every 250-500 operating hours, or annually. Refer to the manual for precise intervals based on operating conditions.
Fuel Filter Replacement:
Recommended every 250-500 operating hours or as needed if fuel quality is poor.
Hydraulic Filter Replacement:
Typically every 500-1000 operating hours, or with hydraulic fluid changes.
Hydraulic Fluid Capacity:
Varies by model, typically around 35-55 liters (9-14.5 gallons). Manual will confirm exact capacity.
Engine Oil Capacity:
Varies by engine, generally 6-8 liters (approx. 6-8.5 quarts). Manual will specify exact capacity and oil filter part number.
Common Wear Points:
Clutch wear, PTO clutch engagement issues, hydraulic pump or valve leaks, starter motor reliability, minor electrical gremlins, front axle pivot wear.
