Engine Type:
Diesel (Specific engine models would require detailed lookup for these tractor series, often turbocharged variants of Case's own or sourced engines like Cummins or Perkins were common in this era).
Horsepower Range:
Varies by specific model (e.g., 2390 ~120-150 HP, 2590 ~150-180 HP, with 2394/2594 likely being updated or turbocharged versions).
Torque Range:
Varies by specific model and engine configuration.
Injection System:
Likely direct injection, potentially with turbocharging on later models.
Engine Oil Change:
Typically every 250-500 operating hours, depending on API service classification and operating conditions. Consult the manual for exact intervals.
Transmission Fluid Change:
Refer to the manual for specific intervals and fluid types. Often around 1000-1200 operating hours.
Engine Oil Type:
CI-4 or higher rated diesel engine oil, viscosity grade SAE 15W-40 is common. Consult manual for exact specifications.
Hydraulic Fluid Type:
HY-TRAN® UTTO (Universal Tractor Transmission Oil) or equivalent meeting Case IH specifications is critical for the transmission, hydraulics, and wet brakes.
Coolant Type:
Ethylene glycol-based antifreeze with appropriate corrosion inhibitors for heavy-duty diesel engines.
Common Wear Items:
Clutch wear, hydraulic pump wear, injector pump issues, and potential for turbocharger seal leaks (if equipped) are common in high-hour units.
Electrical Gremlins:
Corrosion in connectors, worn wiring insulation, and faulty switches can lead to intermittent electrical problems over time.
