I knew this wasn't going to be the best pump. Most with specs like this will be at least $800. This pump lasted 4 washes. I've been washing for over 30 years and know how to properly treat a pump. Sorry i skimped.

1 inch hollow shaft is too short for motor shaft . it slides over motor shaft just shy of 3/8 of an inch. Called and they said use it .. yea when it throws the key my motor shaft takes a hit .THEN WHAT

I'm returning for replacement, hopefully it will be better than first one! Right from the start I had problems installing the pump with the hole not being centered correctly, I knew it was a sign of poor quality and should have sent back immediately, but need pump the next day! In the middle of using the pressure dropped to 0, upon further inspection the one check valve broke into pieces.

I've been using this pump for about 2 weeks now. Roughly 3-4 times a week for about 45 minutes each time.I added full synthetic 10w-30 oil since that is what I had. This pump replaced my AR RKV 4G36 pump. It fit perfectly on my Honda GX390. Removal of old pump & installation of new pump took all of 5 minutes.I was really curious to see if the flow rate was correct or not so this is how I tested it at 3200psi. I have a 15 gallon steel drum. I added 3 gallons of water inside the steel drum & marked it with a sharpie. Stuck my wand with a turbo nozzle in the water. Set my timer for 1 minute. Started my pressure washer. Verified the pressure was set at 3200psi. Pulled the trigger. During the flow rate testing, my pressure gauge read 3000psi. When my timer went off, I let go of the trigger, pressure went back up to 3200psi. I set my motor throttle to idle for about 15 seconds then turned it off. I disconnected my wand to let the water flow to cool the pump while I start removing 1 gallon of water at a time. I removed about 5.5 gallons or so during my testing. I say or so because I was using an old milk gallon jug I was throwing away.You are probably wondering why I was cooling the pump after a 1 minute test. In reality, I got everything ready to do the test. Then I pressured washed for about 30 minutes. When I got done, I set my timer for 1 minute & started my test. You can't just turn off your pressure washer pump off and not cool it down. That will ruin any pump quickly. I also run my pump at 3000psi & not at max of 3200psi.The real question is, will this pump last as long as my other pump did of 6 years. That is the real question. Quality seems good. Sooner or later, I will rebuild my AR pump to have a backup.
