PROBLEM

Show/hide table

Certain 324DL, 324DLN, 325D, and 325DL Excavators that are configured for bio oil may have been shipped with the wrong final drive travel motors. The wrong travel motors will satisfy the operation of the excavator on slopes up to a 30? angle, but a 35? angle is required. A wrong travel motor may affect braking efficiency when working on steep slopes. The travel motors must be inspected and if the incorrect travel motors are installed, the travel motors must be replaced.
