   Today I bought a Troy built pressure washer. Rod through the block. 7.5 hp briggs ohv vertical. I have setting around a 6.5 hp Horizontal Honda clone. Will the pump care if it is vertical or horizontal?    Don

The rotation is counter clockwise looking at the output shaft on each engine. I haven't checked shaft size yet what I am most concerned with is lubrication flow.    Don

Shouldn't make any difference as long as you keep water to it.

I thought that all small gas engines rotated the same way.

As far as finding a power washer with a good pump and bad motor that is unusual
Craigslist is loaded with power washers with bad pumps.

Sounds like he had a bad engine when he bought it so the pump could still be bad if he hasn't tried it yet. Your right I've seen plenty with bad pumps but good engines.

Do you know if the pump is good.

The ones that I have used were oil lubed pumps. It could mess with that.

I recently had to put a new pump on my Craftsman as it must have frozen last winter. I didn't do a very good job draining it last fall. Decent priced Craftsman ones were about impossible to find but discovered Troy Bilt uses the same Annovi pump and they were more affordable.

 

As Chieffan stated as long as it has water there is lubrication so angle shouldn't matter. Here is where mine cracked so you can see where to look for freeze damage and the Annovi tag on the Craftsman washer.

The easiest way to find out if it's cracked is put a hose on it!

     Update. I dismantled the pressure washer. Became instantly obvious that mounting the pump to the horizontal engine would be extremely challenging. So my focus changed to finding an appropriate engine. Back to Craigslist. Found a mower with a 6.5 30$. Guy says  runs good blade hub is broken. I was kind of hesitant because it was a 60 mile round trip. After a few emails I decide its worth a try. When I get there I find that in an attempt to attach a blade he has welded the blade to the crank. Says "that didn't work". Engine starts right up, runs great, no smoke. I buy it and go home.

     Crank shaft on the both engines are the same diameter, same key way. Mower shaft is 1 3/8" longer. I can only remove 5/8" while saving the key way. I found a piece of 7/8 plate in my iron pile & cut spacers for between the pump and the engine cut 5/8 of the crank, Bolted it all back together. It works great now, If I calculate value added and time spent I can pay my self 1.38 an hr. Good thing I am retired.  Don.
