Engine Manufacturer:
Case IH (formerly International Harvester)
Common Engine Types:
Typically feature turbocharged diesel engines, such as Case IH DT-466 or similar IH/Navistar diesel engines.
Horsepower Range:
Varies by model, generally in the 100-200 HP range (e.g., 2090/2094: approx. 115-135 HP, 2590/2594: approx. 170-190 HP).
Torque Characteristics:
Designed for high torque output for heavy-duty agricultural applications.
Injection System:
Inline injection pumps or rotary injection pumps, depending on specific engine variant.
Oil Capacity Estimate:
Typically around 15-20 quarts (14-19 liters) with filter. Specific capacity listed in manual.
Transmission Type:
Powershift transmission (e.g., Case IH 16-speed PowerShift).
Optional Transmissions:
While PowerShift was dominant, some configurations might have offered direct drive or other options for specific markets or applications.
Powershift Capabilities:
Allows for on-the-go shifting between gears without using the clutch pedal.
Transmission Fluid Type:
Refer to manual for specific SAE viscosity grade and OEM specifications (e.g., Case IH Hy-Tran Plus or equivalent).
Wheelbase Estimate:
Varies by model, typically around 100-120 inches (2540-3048 mm).
Operating Weight Estimate:
Ranges from approximately 12,000 lbs (5,443 kg) to over 18,000 lbs (8,165 kg) depending on configuration.
Engine Oil Change Interval:
Typically every 250-500 operating hours, but consult manual for exact recommendation based on operating conditions and oil type.
Fuel Filter Replacement:
Recommended at regular intervals, often with oil changes or as per specific diagnostic indications.
Hydraulic Fluid Change:
Generally every 1000-1500 operating hours or annually, depending on usage and filter maintenance.
Engine Oil Specification:
API CD or CE rated diesel engine oil, typically 15W-40 or 30W. Check manual for exact grade and specification.
Coolant Specification:
Ethylene glycol-based antifreeze mixed with water in a 50/50 ratio for freeze protection and corrosion inhibition.
Common Wear Points:
Wear in powershift clutches, hydraulic pump wear, fuel injection system components, and seals are common maintenance considerations.
Electrical System Concerns:
As with many tractors of this era, electrical connections and wiring insulation can degrade over time, leading to intermittent issues.
Manufacturer History:
International Harvester (IH) was a pioneering American manufacturer of agricultural and construction machinery, later becoming Case IH.
Series Development:
These models represent a significant advancement in IH tractor technology, introducing more powerful engines, enhanced transmissions, and improved operator comfort.
Production Period:
These models were primarily produced in the late 1970s and 1980s.
