Q: Why does the travel motor feel weak when tracking backward compared to moving forward?
TgQPHd|[]
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. TgQPHd|[]

Q: What gear oil specification should be used in the reduction gearbox side?
TgQPHd|[]
A: We recommend using high-quality SAE 80W-90 or 90 gear oil. Always check and fill the oil levels when the excavator is parked on level ground. TgQPHd|[]

Q: How do the internal bearings handle the heavy side-loads from working on rocky slopes?
TgQPHd|[]
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.
