Bolted it on and it was good to go

Bolted it on and it was good to go. Fit on my 6.5HP Briggs motor with a 3/4" shaft. The pump I recived came with a key for the shaft. For what it costs compared to other options I am quite happy with this pump almost paying for itself on the first job.

My sister was going to throw her pressure washer away because it was broken. My husband asked her for it and we purchased this part and it works perfectly! We got a nice pressure washer for the cost of this part.
Can stand the pressure

This is a decent pump, running it with a 5.5hp Briggs removed from a push mower that the bed had rotted through. The unloader valve is adjustable, but to be able to start the gas engine I had to reduce the unloader to almost zero, shut the water supply off (until started) and keep the trigger on the HP gun to relieve ALL sources of load/pressure on the pump. Without doing this I could not pull the starter rope due to the "load".
This pump fits numerous washers and made a very nice homebuilt unit. Plenty of pressure indicated on my test rig. 2700-3000psi. Not a Toy.
