Engine Oil Change:
Typical intervals for diesel tractors of this era are 100-200 operating hours, or annually. Specifics will be in the manual.
Transmission Fluid Change:
Usually 500-1000 operating hours, or every 1-2 years. Manual will specify.
Hydraulic Fluid Change:
Similar to transmission, typically 500-1000 operating hours. Manual will specify.
Engine Oil Viscosity:
Likely 10W-30 or 15W-40 diesel engine oil, meeting API CD or CE classification. Manual will confirm.
Transmission Hydraulic Fluid:
Typically an SAE 80W-90 gear oil for the transmission and a tractor hydraulic fluid (often referred to as UTF - Universal Tractor Transmission Fluid) for the hydraulic system and potentially shared sumps. Manual is critical for correct type.
Coolant Type:
Ethylene glycol-based antifreeze, typically a green type for this era, mixed 50/50 with distilled water. Manual will specify exact type and ratio.
Common Wear Points:
Wear in clutch friction material, transmission synchronizers, PTO gears, and hydraulic pump/cylinder seals are common. Engine wear such as piston rings and bearing clearance also typical.
Electrical Reliability:
Age-related degradation of wiring insulation, starter brushes, and generator output can be issues.
Fuel System Maintenance:
Clogged fuel filters and worn injector pump seals can affect performance.
