Maintenance & Troubleshooting Corner

Troubleshooting: Komatsu PC200-8 Hydraulic Pump Failure

Symptom: Slow or weak operation, especially under load, and high-pitched squealing from the pump area on a Komatsu PC200-8 Excavator.

Solution: This often indicates a failed Hydraulic Main Pump (708-2L-00300) or contamination.

  1. Check the hydraulic oil level and ensure it is clean.

  2. Inspect the pump coupling for damage.

  3. If the pump is worn, replace it immediately with a high-quality aftermarket or OEM-equivalent unit to prevent damage to other system components.


Proactive Engine Maintenance: Cummins QSB6.7

Regular maintenance of your Cummins QSB6.7 Engine is key to longevity.

  • Scheduled Oil Analysis: Use oil analysis every 250 hours to detect premature wear metals, fuel dilution, and coolant leaks.

  • Valve Lash Adjustment: Ensure correct valve clearance adjustment per manufacturer specifications to prevent valve train damage and maintain performance.

  • Cooling System Check: Regularly test the coolant concentration and inspect the Radiator and hoses for leaks or blockages.
