7/8" Shaft Vertical Pressure Washer Pump Rear Inlet/Outlet 3000 PSI @ 2.5 GPM Replacement Pump for Power Washers, Compatible with 308653045, 308653052, 308653078, GCV190 and more

I installed this pump on my Husky HU80709 pressure washer, which originally delivered 2600 PSI at 2.4 GPM. The new pump fit perfectly, except for one mounting hole that needed to be slightly enlarged, a quick and easy fix with a drill. After installation, the washer performed like a beast! The pressure was even better than with the original pump. I’ve only used it for a couple of hours so far, but I’ll update this review if any issues come up or the performance changes. Oh I forgot to mention that I got it for sixty bucks plus taxes, for such price I think it really worth it.

This was a great replacement pump. Its works well. Easy swap

Bought this for my Troy-Bilt 020296 (2500 psi) with the Honda engine GCV160 engine. remove 3 bolts, remove pump. New pump inlet and outlet ports were very short, so I removed the inlet and outlet extension ports from it and my old one and installed the old ones on the new pump. I wire brushed the old ones and installed new o-rings before installing. Placed a block of wood on the floor to support the pump to make sure the keyway is lined up properly. I did not tip the washer to vertical as I've seen on some videos - to each his own. Installed 3 original bolts and tightened it down. No issues. Even though this pump is rated for higher horsepower engines and higher psi, it seemed the pressure was same as original. Works like new. Did my porch and sidewalk right away with no leaks.

I used this to replace the pump on a Troy Bilt 2700 pressure washer. The original pump has 311039 indicated for the model number. In case you are replacing this one you should know this replacement doesn't have the hole on one of the legs for the oil drain plug. It is also rear mount (as they clearly state in the description) so the hoses will come out the back and may get in the way of your chemical bottle. Neither of these were a big deal for me as I already removed the chemical bottle. The engine oil is also easy enough to change by tipping over and draining out of the fill hole. One last retrofit I had to do was use some washers for spacing to allow me to bolt it tightly. I used a total of 4 washers in two places on each bolt. It is mounted tightly and seems to work fine. At half the cost of a direct replacement I'm happy with it. Note, there is also a power adjustment on the pump so if your engine stalls when you try to run it (too much power for your engine) you can adjust the power down until you get it in the range you can use.

You wouldn't think by looking at the original pump that is off a 12 year old washer from Costco but it does (see pics). Still veritical 7/8 shaft, just has a totally different mounting setup but the mounts align just fine. I used the original bolts that or more beefy and I hate allen heads. Getting the exact pump off the Simpson sight was amout 2x the price. Also left the original key on the shaft. No way to check if it meets performance specs but a quick break-in to check for leaks and it works fine for a cheap pressure washer.

Great and cost effective replacement for the pump that failed on my RYOBI pressure washer. Factory original part (made in China) would have cost around $140 so this replacement (made in China) was a better choice especially for the price. Installation was a breeze and was a perfect fit. Absolutely no difference from what I could tell between the original factory pump and this replacement. It is great to have my pressure washer functional again at a fraction of the cost of buying a replacement pressure washer!!!

Easy to install and the it works great. I am getting the same performance out of this as when the pressure washer was new. How long would it last? we will see, but for now it is doing the job just right. I use the pressure washer about 5-6 times a year.

Fantastic pump. Great replacement on my Yamaha 3100 psi pressure washer. Easy to install. Doesn’t leak and yields great pressure.

Perfect fit, works fantastic!
