OEM Technologies 3400 PSI 2.5 GPM Horizontal Pressure Washer Pump Kit 90029

No problems. All the holes match, great pressure.

Great product and well built. I bought this pump because I had to replace one that had some plastic internal parts and you cannot buy those repair parts. On this pump the parts are metal parts instead of plastic so the quality is really great. Also, parts are easy to find for this pump. it bolted right on perfectly with no issues at all. I would recommend this pump to anybody else.

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.

I gave this OEM Technologies 90029 4 stars but it may be 5. Longevity ? - who can say, I gave it 3 stars. It took less than half hr to remove the old pump and to install this new pump. No issues with the 3/4 shaft key way or 4 bolts . After the water and pressure hose connections, I started the engine which is a Harbor Freights 6.5 HP / 212 Predator. Pressure built up almost immediately and I began the pressure washer test. ALL is well ! Tomorrow I will run the pressure washer for an hour or so. I noticed right away that the thermal relief valve was working in between hi pressure operation and its release. This is a good thing ! I believe this pump is equivalent or better than whats on brand new pressure washers selling for $500 or $600 - or even more.

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.

Perfect, great pump, last one lasted an astonishing 14 years with weekly use.

Perfect replacement works great

I used this pump 1 time - the second time I used it the oil came out. I wanted a new one. Manufacture said to bring it to authorized service center place to have it looked at. I asked for them to give me a place to bring it to. They gave me 4 places in Illinois. I live in New Jersey. Asked again for a place in Jersey. Sent me 4 places in Illinois. I will not buy from them again . They will not make it easy for you. I told them I will send pictures of broken parts. Not good enough to them. I lost time and money. Had to buy other pump in jersey. Not Amazon.
