OEM Technologies 3400 PSI 2.5 GPM Horizontal Pressure Washer Pump Kit 90029 | Horizontal Axial Cam Replacement Pressure Washer Pump Kit, Gas Pressure Washers, 3/4" Shaft, Includes Hardware & Siphon Tube

This worked perfectly on my pressure washer. Honda GC 190 motor on a simpson frame. All parts included.Super easy install.

After a few hours it’s running great. Much cheaper than buying a new power washer.

My Simpson pressure washer (3100 PSI, 2.5 GPM) has served me well over a number of years, but its water pressure had dropped to the point that made cleaning my driveway very difficult. After reviewing some Youtube videos, I saw that the pump could be replaced. This unit is an exact OEM replacment for my unit, and the new pump restored the original capability to clean. Some time after I originally purchased the washer, I bought a surface cleaner, but I could not get it to clean concrete surfaces with mold, mildew, stains, etc. After I replaced the pump, the surface cleaner works well, and this attachment really speeds up cleaning my driveway. The pump is fastened to the gasoline engine with four allen key metric bolts that were somewhat stuck, but a little leverage on the allen key loosened them. The rest of the replacement was easy. Note that there is an alternative, less expensive approach to pump replacement: Ebay sellers provide new seal and valve kits to allow rebuilding the original pump, but I didn't realize this until after I had replaced my pump. When I disassembled my pump to see why it failed, I found that the water seals were worn and the valves had worn out; so a seal kit + a valve kit for a total of about $60 would likely have restored the original pump.

This is a good replacement for my machine. It was an easy swap out and works like new. The only negative is there is no way to change the pump oil. Not that I ever did and probably why the original failed 🤪

This pump worked out great for a replacement on my pressure washer. This one has a little more power then the last pump and the cost wasn't bad at all. Fit like a glove and didn't have to make any adjustments at all.

Worked for 20 minutes, then stopped working. Something to do with valving; pressure builds up to the point the engine stalls. To late to return and it'll be interesting to see how they handle the warranty

This was a perfect fit for my Coleman Powermate 2750. The Honda motor handled the extra 250psi just fine, the only modification I made to it was a 90 degree hose fitting to make it easier to hook up the hose. I did have to modify an allen wrench , shorting it, to get the old pump off. Well worth the money.

Excellent replacement.

Good packaging, minimal documentation.Was easy to replace the old one, and worked great out of the box. Good value.
