Cooling Medium:
Liquid (Water-Glycol Mixture)
Cooling System Capacity:
Refer to manual for specific capacity (typically 15-25 liters)
Oil Type:
API CG-4 or CH-4 rated diesel engine oil (e.g., 15W-40) or specific CASE I.H. approved lubricants.
Oil Capacity:
Refer to manual for specific capacity (typically 12-18 liters)
Valve Timing Specifications:
Detailed specifications for intake and exhaust valve opening/closing points and lash adjustments.
Governor Type:
Mechanical governor system (likely based on centrifugal weights) for precise engine speed control.
Transmission Type:
Likely a partially or fully synchronized manual transmission with power shift or creeper gear options (e.g., 16-speed, 20-speed).
Optional Transmission:
Possible powershift or advanced synchronized gearboxes depending on trim/configuration.
Gear Selection Method:
Manual lever operation with potential power-assisted shifting.

Every 500 operating hours or as needed based on fuel quality and monitoring.
Hydraulic Filter Replacement:
Every 1000 operating hours or annually, depending on usage and system cleanliness.
Coolant Type:
Permanent Type Antifreeze (Ethylene Glycol base) with corrosion inhibitors, mixed 50/50 with distilled water.
Brake Fluid Type:
Refer to manual; typically SAE J1703 or DOT 3 brake fluid if applicable for separate brake systems, otherwise integrated with hydraulic fluid.
Transmission Oil Viscosity:
Refer to manual, but commonly SAE 80W-90 gear oil for certain components or UTF for the integrated system.
Common Wear Points:
Wear on clutch components, transmission synchros, hydraulic pump seals, and PTO clutch packs are common areas for detailed inspection and potential repair.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical issues. Inspection and replacement may be necessary.
Cooling System Maintenance:
Corrosion and leaks in the radiator and coolant passages can occur if coolant is not maintained correctly.
