Troubleshooting & Maintenance FAQ for PC600-6 Main Pump

1. Why is my PC600LC-6A experiencing slow hydraulic movements?
Slow movement often indicates internal leakage within the 708-2L-00721 main pump. Wear on the cylinder block or piston shoes reduces the volumetric efficiency. We recommend a pressure test; if flow drops significantly under load, a replacement is necessary to restore speed.
2. What causes unusual noise coming from the 7082L00721 hydraulic pump?
Cavitation or air ingestion is the primary cause of pump noise. Check the suction line and hydraulic oil level. If the noise persists, the internal bearings or the swash plate of your PC600-6 pump may be damaged, risking metal contamination throughout the system.
3. Why Choose This Main Pump Replacement?
Our pumps feature an OEM-standard tri-metal structure for maximum durability. We are trusted by repair shops and equipment fleets worldwide because our parts meet the rigorous demands of mining and construction environments.
