Displacement 2590:
Approximately 504 cu in (8.3 L) – Case 8.3L engine
Horsepower 2090 Rated:
Approx. 165 PTO HP (may vary slightly by specific configuration)
Horsepower 2590 Rated:
Approx. 190 PTO HP (may vary slightly by specific configuration)
Torque Characteristics:
High torque rise for excellent lugging ability under load.
Fuel Injection Type:
Mechanical Direct Injection
Injection Pump Type:
Likely Bosch or similar rotary/inline injection pump.
Fuel Filter Part Number:
Specific part numbers would be detailed in the manual, but typically an inline fuel filter.
Oil Capacity:
Specific capacity detailed in the manual, typically around 18-20 quarts for this engine size.
Oil Specification:
Likely API CE or CF rated heavy-duty diesel engine oil, with viscosity dependent on climate (e.g., 15W-40).
Coolant Type:
Typically a 50/50 mix of permanent antifreeze and water.
Transmission Type:
Powershift (e.g., 16 forward, 12 reverse or similar configuration)
Optional Transmission:
May have offered a standard gear transmission in some markets or configurations, though Powershift was a key feature.
Powershift Capabilities:
Allows on-the-go shifting between gears without using the clutch pedal, enhancing productivity and operator comfort.
Torque Limiter Clutch:
Integrated clutch system designed to protect the transmission from shock loads.
Transmission Fluid Type:
Specific to the powershift unit, often a dedicated tractor hydraulic fluid (THF) or specialized transmission oil.
Transmission Fluid Capacity:
Detailed in manual; typically significant capacity for powershift units.
Wheelbase:
Refer to manual for exact dimensions, but typically long wheelbase for stability.
Operating Weight:
Significant operating weight, likely in the range of 15,000 - 20,000 lbs (without ballast).
Ballast Capacity:
Designed to accept significant ballast for traction enhancement.
Rollover Protection:
ROPS (Roll-Over Protective Structure) likely standard or available, crucial for operator safety.
Braking System Design:
Heavy-duty braking system designed for safe operation of a powerful tractor.
Operator Station:
Cab designed for operator comfort and safety, with visibility and control considerations.
Engine Oil Change Interval:
Typically 250-500 hours, depending on operating conditions (detailed in manual).
Fuel Filter Replacement Interval:
Usually every 250-500 hours or annually, as specified.
Hydraulic Fluid Change Interval:
Typically annually or every 1000-1500 hours, depending on usage and fluid condition.
Hydraulic Fluid Specification:
Consult manual for specific THF or hydraulic fluid specifications. Common types include Case IH Hy-Tran or compatible fluids.
Transmission Fluid Specification:
Crucial to use the correct specification for the powershift unit; manual will list exact requirements.
Powershift Wear:
Like many powershift transmissions of the era, wear in clutch packs or hydraulic control valves can occur over time with heavy use.
Turbocharger Maintenance:
Regular oil changes are critical for turbocharger longevity; carbon buildup or bearing failure can occur without proper maintenance.
Hydraulic System Leaks:
Potential for seal deterioration or hose wear leading to hydraulic leaks, requiring careful inspection and component replacement.
