Engine Family:
Case IH DT/DTA Series Diesel Engines (e.g., 5.9L, 8.3L Cummins, or Case-built engines depending on specific model variant and year)
Horsepower Range:
Approximately 100 HP to 250+ HP (varies significantly by specific model: 2290, 2390, 2590, 2094, 2294, 2394, 2594)
Torque Characteristics:
High torque at low RPM, suitable for heavy draft work.
Injection Type:
Direct Injection Diesel
Cooling Method:
Liquid-cooled
Oil Type Recommendation:
API CG-4 or CJ-4 rated diesel engine oil, viscosity typically SAE 15W-40 (refer to specific model year for precise specification).
Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions and oil type.
Hydraulic Fluid Change:
Typically every 1000-1500 operating hours, or annually. Filter replacement is more frequent.
Transmission Oil Change:
Varies by specific transmission, but generally between 500-1000 operating hours.
Coolant Type:
Permanent type ethylene glycol coolant (green or orange depending on formulation) with de-mineralized water. Follow manufacturer recommendations for specific additive packages.
Hydraulic Fluid Capacity:
Varies by model, but generally in the range of 15-30 gallons (57-114 liters) for the main hydraulic reservoir.
Common Problems:
Wear in the hydraulic system (valves, pumps), front axle pivot wear, electrical connection corrosion, clutch wear (especially in heavy use), turbocharger issues (on turbocharged models), cooling system leaks.
Preventative Maintenance:
Regular fluid analysis, keeping electrical connections clean and sealed, proper lubrication, and timely filter changes are crucial for longevity.
