Works with Honda GX160/Simpson-brand pressure washer
I have a Simpson pressure washer from the mid-1990's with a Honda GX160 5hp engine. Originally the unit came with a Cat pump. It had been sitting unused for at least six year before I pulled it out of storage where it hadn't been stored correctly. First changed the spark plug and the engine started but died. The carburetor needed to be replaced after we failed to clean it well enough to get it running correctly, which was only $16, and then once the new carb was on and the engine running perfectly we found out the seals on the Cat pump had gone bad and had at least one leak, meaning the machine was way down on pressure. After looking and realizing that I couldn't find info on the correct o-rings and seals and would have to buy them blindly hoping I lucked out, I started looking at replacement pumps and after a few hours decided on this one. The old pump pulled right off using two pry bars, one on either side, pulled the mounting plate, and this new unit slid right on, shaft and key were a perfect fit, bolt pattern matched, and I used the bolts that came with the new pump since they were longer. After an much needed oil change and switch to synthetic 10w30 for the Honda engine, it's safe to say that this 25 year old pressure washer is actually running better now with this pump than it was with the old unit. I don't know how long this pump will last, but I just lightened up a driveway with it and now am going to be pressure washing the neighbors house for them. We're on well pressure at 60PSI, and it's still spinning the turbo tip once the air clears out of the line. I'm very happy with this.

an exact bolt on replacement, good value
I received this pump replacement a month ago, i have a 5hp Generac pressure washer that had bad pump valves and the age of the unit made it impossable to find replacement parts for. I found this pump on Amazon, it appeared to fit my application, so i gave it a shot. I made sure to measure the bolt pattern and shaft size to be sure of the fit prior to ordering, it was a perfect match, absoutly no issues installing and starting. The replacement pump restored my pressure washer to like new condition at a fraction of the cost, i've only had a few oppportunities to use it so far, but it's working flawless to date. I can't speak for the longevity at this moment, but keeping my fingers crossed that it's performance is an indicator to the life i can expect to get from this pump.

Good replacement but not an exact fit for Troybuilt
This came with the wrong hardware for my Troybuilt 020207. It comes with adapter washers, but the bolts were too short and caused a trip to the hardware store. With that said, my particular pump was likely once a return item though. The box contained parts that were not supposed to be in there, and the instruction sheet was greasy and ripped.

Nothing lasts forever!
The new pump was very easy to install and the pressure washer was up and running in one half hour. Just being able to sources the new pump and have it delivered made my world so much more productive. Thank you Amazon for your service and vision, technology and productivity are not always in everyone’s best interest, I am just very appreciative of the opportunity to be able to source the parts needed and not have to buy a new machine. It kept the old machine from the Land Fill and contaminating our ground. There is ‘Real Value’ in the service you offer, it’s not always just about the money. Peter

Fits my AR SJV pump
The threaded portion of this injector was a bit longer that the original AR injector so it bottomed out before reaching the O ring. I simply wrapped some teflon tape around the threads and tightened it gently. Works like a charm. I got 2 of these for less than I paid for one which isn't going to be delivered for a week. Got these the next day and was able to stay on schedule for the job.

Product not working as expected
As of now, this downstream injector is not working for me. I setup to wash my house over the weekend and unfortunately it was an absolute fail 😮💨 No soap of SH came out as expected. I made sure the flow was correct and I had the injector set to be wide open to get the maximum flow out of it. I used my J Rod soap nozzle for low soap rinse and high soap rinse and just to be sure, I used the supplied black soap nozzle. With the setting wide open, no soap pulled at all. I poured 3 gallons of 10% SH into a 5 gallon bucket mixed with 2 cups of soap and the rest water to dilute. I put weight on the tube to make sure it stayed submerged in the chemical to draw it. After that, I made sure that there were no leaks and everything was setup as expected. To somewhat get something done I had to use my foam cannon filling that up with the chemical but it didn't seem strong enough even at the highest setting. This was a disappointment and a lot of work unfortunately.

This is a good pump!
Replaced a broken 2700PSI 2.3GPM pump on a Craftsman power washer. Wasnt a perfect fit, had to add some spacers and find 1 longer bolt than what was supplied, but I expected that because it wasn't the identical pump that I had. It was an upgrade, for sure! This thing will blast off decals now! Only used about an hour, but so far I'm impressed. Much cheaper than buying a whole new power washer!

Was used and doesn't fit standard pressure washers
I received a used product, or attempted use. Be warned that none of the fittings will fit standard pressure washers. The quick release is way too big for standard pressure washers.
