DH55 DH60 Excavator Machinery Parts 1-2 Stage Travel Gearbox Assembly Planetary Gear Sun Tooth Bearing Gasket

The ExcavatorTravel Motor is the "leg and foot" power source of construction machinery such as excavators and crawler cranes. Essentially, it is an integrated assembly of a "hydraulic motor + reducer". It is responsible for converting the pressure energy of hydraulic oil into huge torque to drive the equipment to move.

1. Unusual or excessive noise: Gear wear, bearing breakdown, lack of lubrication or oil deterioration.
2. Oil seepage failure: Worn seals, housing fractures, overfilled lubricating oil level.
3. Weak driving force / Track drift: Worn gears or bearings, failed brake release, inconsistent left‑right reducer performance.
4. Excessive temperature rise: Overloading, ineffective lubrication, poor heat dispersion, brake dragging condition.
5. Gear skipping or jamming: Fractured gear teeth, impaired planet carrier, intrusion of external debris.
