- Purpose: The final drive oil lubricates the gears and bearings in the final drive system, which transmits power from the engine to the tracks.
- Coolant
- Purpose: The coolant regulates the engine temperature by absorbing and dissipating heat. It is essential to maintain proper engine temperature, especially during extended operation.
- Recommended Fluid: Cat ELC (Extended Life Coolant) or equivalent.
- Change Interval: Every 3,000 hours or 3 years, whichever comes first.
- Procedure: Drain the old coolant from the radiator and engine block, flush the system if necessary, and refill with fresh coolant. Be sure to bleed the air out of the cooling system to avoid overheating issues.
