FAQ

1. Is this water pump compatible with my Komatsu PC400-6 excavator?
Yes, the 6D140 engine was a standard power unit for the PC400-6 series. However, we strongly recommend checking your original pump part number (e.g., 6212-61-1205) against the numbers listed above to confirm fitment, as engine configurations can vary by serial number range.

2. What should I check before installation?
Before installation, inspect the new pump for any shipping damage. Ensure the gasket surface on the engine block is clean and free of old gasket material. Always replace the coolant and use a new gasket (sold separately) to prevent leaks. Do not overtighten the mounting bolts, as this can warp the pump housing.

3. How often should this water pump be replaced?
As a preventive maintenance measure, the water pump is typically replaced during a major engine overhaul or when signs of failure appear (e.g., coolant leaks, bearing noise, or wobbling pulley). For heavy-use excavators, inspection every 2,000 to 3,000 hours is recommended. Immediate replacement is required if coolant leakage is detected near the pump shaft.
