AR Vertical Shaft Pump For 7/8" Shaft Size
Simple replacement pump for pressure washers that have the pump mounted underneath the engine. Fits engines with 7/8" shaft only, so please check your shaft size before ordering.
This is the most common replacement pump for light-duty use. Rated to last for 300 hours of use.
The most common cause for premature failure of any pressure washer pump is overheating. This is frequently caused by allowing the engine and pump to run without pulling the trigger for several minutes. The only way your pump can keep cool is when water is running through it.
The other cause for failure is infrequent use. Find excuses to use this excellent power tool once every month or so.
