I am replacing the pump on my sisters pressure washer. The only experience with pressure washer pumps was mine which came off with the 4 bolts. This one looks like it is also threaded into the output shaft. So how do I unbolt it? It is a General Pump TH3020G.

Maybe the pump is rusted a bit to the engine shaft? I pulled somewhat gently with my hands. I didn't want to put too much force on it incase I was wrong. |

It looks like there are two major assemblies, the pump and the adapter to the engine. #72 and the other parts are the adapter, and the pump just bolts to that. Do you have to remove that drive adapter, or will the replacement pump bolt up to that? I have the adapter unbolted from the engine. I'll try to unbolt the pump from the adapter and see what happens. actually i'll have to cut the bolts off. I couldn't get an allen keys on them. not enough room. |
