         In our previous experience, the common faults of gear final drivess are: severe noise and pressure fluctuations; insufficient oil delivery: the hydraulic travel motors is abnormal or has a seizure phenomenon. When our Komatsu excavator has the above situation, we should promptly turn off the machine for a full inspection. When the above situation occurs, we should focus on the following areas:

         First: the filter of the final drives: the filter of the final drives is blocked by dirt and cannot function as a filter.

         Second: axial clearance and radial clearance: If the gap between the two is too large, it will lead to insufficient oil delivery.

         Third: final drives body part: check the final drives body for cracks and pore leakage
