Honda GX390 engine - 11.7 HP and a belt drive Cat triplex pump. 4,000 psi at 4 gpm. I added the included quart of 10w-30 oil, some gas, hooked up hoses, ran water through the pump, etc. The Cat pump came with oil so nothing to do there.

The engine easily started on about the third pull - it was easier to start than my 5 HP residential Honda powered 2,500 psi pressure washer. I was quite amazed.

The frame is aluminum and the washer is nicely balanced on the large pneumatic tires. What a difference between 2500 and 4000 psi - wow.

Pressure Washer Direct shipped this out right away after I ordered it - maybe so I wouldn’t change my mind and cancel the order :laugh: This was expensive but I think I made a good decision and I’m quite pleased, at least so far.

And belt drive too? Interesting-I’d love to see some pics of the drive setup!

I have a similar power washer with the Honda engine, Cat pump, 4gpm and 4,000 PSI. It's a great power washer.........If that can't get the spot off or the stain out, chances are it will just blow a hole through the material......:laugh::lol:

Make sure to never put the multi viscosity motor oil in the Cat Pump. It needs a special, straight weight, non detergent oil, which per the Cat pump I own, I seem to recall it's a straight 30 weight. I get the Cat oil in the bottle from Northern Tool, even though its just a non detergent, straight weight oil.

With the pumps as costly as they are, I am sticking with the oil right from Cat to make sure it's 100% correct. But I do know that the multi viscosity oil with detergents in the Cat pump will turn to Milk in a flash with even a tiny bit of moisture which happens easier than most realize...............then the temp in the pump skyrockets because the lubrication quality of the oil drops like a rock once there is moisture in it............and before you know it, it's time for a new Cat Pump and they are $$$$.......

Even my old as the hills 1500 PSI Cat pump specifically says that about the oil.

Probably going on 20 years with no trouble, I did add a low input water pressure cutoff to the engine, input water pressure drops
below 15 PSI, it kills the engine.

Done seen several friends burn theirs up from a kinked hose or broken hose, those pumps burn up super quick
with no input water.

I’ll put up some pictures of the washer tomorrow. I want to check the pulleys to be sure they are tight on their shafts, there was one report of loose pulleys on a customer review of this model.

Roger on using the recommended oil in the pump, I have Cat’s website page about oil bookmarked. I’m fairly anal about following manufacturer’s recommendations.

Here's a few pictures of the pressure washer. I'm impressed with the build quality, especially the belt(s) cover - one screw on the top and you can pull the cover right off. About the only thing I would change is to move the pump a bit further out from the engine to make access to the inboard side of the engine a bit easier. Other than that - well done Pressure Pro.

The build does look very nice-hopefully you made note of the belt specs so if ever a replacement is needed you’ll have the numbers without having to read them from a work or destroyed belt.

Yessir, I took two or three pictures of the belts for a record of the numbers.

Very nicely made.
I like the way they attached the pulleys to the shaft with the split, tapered bushings. Way better design than straight bore with keys.
Also the "cogged" belts will take less power to conform around the smaller diameter drive pulley and generate much less heat than a standard v belt.
Way better machine than mine although I really liked the fact that any part of mine including internal engine parts for the Kohler can be procured through my local Stihl dealer.
My PW works well for the tasks I ask of it but it is not highly rated in terms of pressure and gpm, but I think it is still a decent machine.

I did a test with one like that on stream flow and great to put out fires with little water and will over come high winds too! I had the Belt Drive type on my Water Tender I sold a while back. Never needed to do anything to it is 8 years except change oil and drain water from the pump in the winter time. I also sprayed WD40 inside the inlet when running on a idle to wet the pump insides to not rust which they will. Now I have a direct drive and happy with it except the pump rusted a little over the winter once and I had to take it apart to clean the internal valves.
