CAT 320C 320D Travel Motor Final Drive Gearbox

CAT 320C 320D Travel Motor Final Drive Gearbox

Product Overview

The travel motor final drive gearbox is used in the track drive system of Caterpillar 320C and 320D excavators. It combines the travel motor and planetary reduction drive to transfer hydraulic power to the crawler track. Different 320C and 320D configurations may use different final drive part numbers, so the original part number should be confirmed before ordering.

Product Features

Travel Motor and Final Drive

The assembly transfers hydraulic power from the travel system into mechanical rotation and reduces the output speed to provide the torque required to drive the excavator crawler.

Planetary Reduction Gearbox

The final drive uses a planetary reduction mechanism to increase output torque and provide the required travel speed for the excavator.

Heavy Equipment Application

Designed for Caterpillar 320 series excavators used in construction, earthmoving and general heavy-duty applications.

Common Travel Drive Problems

• Weak or slow travel on one side
• Abnormal noise from the final drive
• Hydraulic oil leakage
• Track movement problems
• Reduced travel power
