FAQ

Q: How can I confirm this travel motor fits my excavator?
A: Please check the part number stamped on your current travel motor. The primary numbers are MAG-85VP-1800 or 278-6920. Verify your machine model (e.g., 312B, 320B) and serial number against our compatibility list. We recommend comparing mounting dimensions and spline count if possible.

Q: What is the typical installation procedure for this final drive motor?
A: Installation should be performed by a qualified technician. The process generally involves: 1) Safely supporting the machine and removing the track. 2) Disconnecting hydraulic lines and electrical connections. 3) Removing the old motor and cleaning the mounting surface. 4) Installing the new motor with new seals and O-rings. 5) Refilling with the correct grade of hydraulic oil and bleeding air from the system. Torque all bolts to manufacturer specifications.

Q: What maintenance is required to maximize the lifespan of this travel motor?
A: To ensure long service life, follow these guidelines: 1) Regularly check hydraulic oil levels and condition. 2) Change hydraulic filters at recommended intervals. 3) Inspect for external leaks around seals and fittings. 4) Avoid operating the machine with a clogged hydraulic filter or under extreme loads for prolonged periods. 5) Store the motor in a clean, dry environment if not immediately installed.
