Water-cooled
Oil Type Recommendation:
Specific API CD or similar diesel engine oil (refer to manual for exact viscosity and spec)
Gearbox Type:
Constant mesh, sliding gear (typical for the era)
Gear Speeds:
Likely 8 or 12 forward speeds and 4 or 8 reverse speeds (specifics in manual)
Clutch Type:
Dry, single or dual-plate clutch
Transmission Oil Type Recommendation:
Dedicated transmission/hydraulic fluid (e.g., IH Hy-Tran or equivalent - consult manual)
Drive Type:
