Additional information

This pressure washer pump kit, part number 706385, mounts to the engine and draws in water from the supply hose, then pressurizes it for delivery through the high-pressure hose and spray wand. The kit includes the pump assembly required for replacement.

If your pressure washer has little or no pressure, leaks from the pump housing, or produces inconsistent spray output, the pump may be worn or damaged. Visible cracks, excessive vibration, or water leaking from seals are common signs that replacement is needed.

Disconnect the spark plug wire on gas models or unplug electric models before starting the repair. Shut off the water supply, relieve system pressure, and disconnect hoses before removing mounting bolts. Install the replacement pump securely, tighten all connections, and check for leaks before restoring power and water supply.
