Excavator hydraulic systems rely on stable pump performance. When operators experience unstable pressure or excessive noise, productivity suffers.
Valve plate wear
Control piston leakage
Oil contamination
Cavitation from poor inlet conditions
Worn piston shoes
Shaft misalignment
Replace valve plates and piston kits.
Ensure proper oil grade and filtration.
Inspect inlet lines and case drain.
Timely troubleshooting improves excavator performance and reduces downtime.
