Q: Why does the travel motor feel weak when tracking backward compared to moving forward?
A: This issue is usually caused by uneven wear on the internal valve plate or a misadjusted counterbalance valve. Replacing the motor block restores equal pressure and torque in both directions.

Q: How do the internal bearings handle the heavy side-loads from working on rocky slopes?
A: The main spindle utilizes heavy tapered roller bearings. These are engineered to support high axial and radial loads, preventing housing deflection on uneven ground.
