Excavator Parts 4708769 336F Travel Motor 336F Final Drive 470-8769

The Caterpillar 336D and 336E are compact excavators that are commonly used in construction and earthmoving applications. The "Final Drive" of these machines refers to the components responsible for transmitting power from the engine to the tracks or wheels, enabling the machine to move.

 

For both the Caterpillar 336D and 336E models, the final drive is typically a planetary gear system, which includes a motor, a gear reducer, and a set of gears. The motor receives power from the Hydraulic Pump and converts it into rotational motion. This motion is then transmitted through the gear reducer, which increases torque and reduces the speed to provide efficient power transfer to the tracks or wheels.

 

Replacing a final drive can be a complex process, as it involves removing and reassembling parts of the excavator's undercarriage. It's often recommended to have this done by a professional service provider who has experience with Caterpillar equipment.

 

If you're experiencing issues with your final drive, such as excessive noise, reduced speed, or difficulty in moving the machine, it could be a sign of a problem that requires attention. Common issues might include worn-out bearings, damaged gears, or leaks in seals.

 

To ensure proper maintenance and longevity, it's important to follow the manufacturer's recommendations for regular inspections and servicing. Regular lubrication of moving parts and cleaning the final drive area can also help prevent potential problems.
