Engine Family:
Case IH 'D' Series Diesel Engines (e.g., D177, D201, D236, D268, D310, D358 - specific variants apply to different models within the series).
Configuration:
Naturally Aspirated and Turbocharged 4-cylinder and 6-cylinder Diesel Engines.
Horsepower Range:
Approximately 50 HP to 100+ HP, depending on specific model and engine variant (e.g., 1190 ~50-60 HP, 1690 ~90-100+ HP).
Torque Characteristics:
Designed for strong low-end torque for pulling heavy loads.
Injection Type:
Direct Injection (DI) with mechanical fuel injection pumps.
Displacement:
Engines range from approximately 3.0 liters (e.g., D177, D201) for smaller models to 5.9 liters (e.g., D358) for larger models.
Engine Oil Change:
Typically every 250 hours or annually, whichever comes first. Requires specific CI-4 or CJ-4 rated diesel engine oil.
Air Filter Replacement:
Inspect every 250 hours, replace as needed. Maximum interval typically 500 hours or annually.
Fuel Filter Replacement:
Replace every 500 hours or annually, or if fuel system issues arise.
Hydraulic Fluid Change:
Typically every 1000-1200 hours, or bi-annually, depending on operating conditions and fluid analysis.
Engine Oil:
API Service Classification CI-4 or CJ-4, SAE 15W-40 recommended for most operating temperatures. Check manual for specific viscosity grades.
Hydraulic Fluid:
Case IH Hy-Tran UT (or equivalent UTF - Universal Tractor Transmission Fluid) meeting John Deere J20C or New Holland CNH MAT 3525 specifications.
Transmission Oil:
SAE 80W-90 GL-4 gear oil for manual gearboxes. Powershift transmissions may require UTF.
Coolant:
Ethylene glycol-based antifreeze/coolant mixture (typically 50/50) for freeze protection and corrosion inhibition.
Engine Starting:
Glow plug system issues, injector pump wear, or starter motor problems can affect cold starts.
Transmission Shifting:
Wear in synchronizers, clutch pack issues (in powershift models), or hydraulic control valve problems can lead to difficult shifting or engagement.
Hydraulic Performance:
Loss of hydraulic power, slow lift, or erratic operation can indicate pump wear, leaks, or valve issues.
Electrical System:
Corrosion on connections, aging wiring harnesses, and failure of dashboard components can occur over time.
Manufacturer:
Case IH (formerly Case Corporation, established in 1842), a major manufacturer of agricultural and construction equipment.
Series Introduction:
These models represent a significant line of utility and row-crop tractors from the 1980s and early 1990s, succeeding earlier Case IH designs.
Key Innovations:
Introduction of more powerful engines, improved hydraulic systems, and enhanced operator comfort for their time.
Production Years:
Primarily 1980s to early 1990s. Specific start/end dates vary by model (e.g., 1190 likely early to mid-80s, 1594/1690 extending into early 90s).
Manufacturing Locations:
Likely manufactured at Case IH facilities in North America (USA, Canada) and potentially Europe.
