OEM Technologies 90029 Replacement Pressure Washer Pump Kit, 3400 PSI, 2.5 GPM, 3/4" Shaft, Includes Hardware and Siphon Tube, for Residential and Industrial Gas Powered Machines

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.

The front work great when it came in one corner it was broken off but it was we made it work but it was affected and it was always good enough to refund the money and so they they're good partner you know being on a prime VIP prime remember you know they do me right

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.

Honestly impressed! My pressure washer works like new again

Very, very happy to find this part for my Honda GC160 5hp horizontal shaft preasure washer. Looked great out of box, in 10mins had it on motor with no problems. Suggest use of Never Sieze on bolts and shaft key. Bolted up fine and tested great all about within 15mins. Lots of pressure for home use on muddy things. Other part offered to replace General Pump TH3000 from the MN assembly's builder was about 2x the price, not stocked close and was 2plus weeks out so I cancelled that order.

It failed after brief use I couldn’t return it

I was skeptical to buy this pump regardless of all the good reviews I read. I’m very satisfied with this product. I normally don’t leave reviews but I figured this would help someone else who is thinking about buying this pump.
