Machinery Troubleshooting & Maintenance

Case Study: Hydraulic Power Loss in KOBELCO SK200-8

Problem: Sudden drop in hydraulic pressure and slow arm movement.

Solution: Inspection revealed internal leakage in the Main Control Valve. Replacing with OEM-quality YN22V00002F1 restored full system pressure and cycle speed.

General Maintenance Tip:

For Komatsu PC300-7, ensure the coolant float switch 7861-92-4800 is clean. A faulty switch can cause false overheating alarms, leading to unnecessary downtime.
