Got it off, removed rods and pistons, time to see if I pull the crank and change ALL gaskets, seals and valves.

There is a good bit of rust on the end of the crank, we'll see how it comes off

it was a fairly small piece.just when I put the chisel in the crack, attorney hairline piece came off.but I will go ahead and use the heavier mallet to knock it off. It doesn't have a threaded end on the crank, just a straight shaft with a key slot

Thats what I did and the metal slightly chipped. Seems a bit brittle so I only used a rubber mallet to smack it

Ok I definitely have the A model then. When you got your overhaul kit, what did it come with? Looks like I'll need cylinder gasket, rings (had oil blow by), and new valves. Dont know if I should bother taking off the unloader assembly and put in new gaskets there and mess with the crankshaft...

Is the difference in valve size very noticeable to the naked eye or are they subtle enough to need to measure them?

Speaking as I cant find a parts breakdown for an A model, if I "needed" a manifold for it, I'd have to go with the newer one. Same with the intercooler tube. Can only find the part number for the R15B

Just because I like the look I wonder if I can use the LP intake manifold to mount the air filter on top. I like things being OEM but also like updates

Oh yeah, and the low pressure intake valves look like they are the same size, you said the 15B models went with all different sized valves.

I think I read somewhere that it was jist the R15 that had the hand hole, the R15A didnt have it. I could be wrong. Mine has no hand hole. And the air intake doesnt have the hole on top of the manifold for an air filter, its on the bottom, which would leave me to believe its an R15A. As...

Took the head off: See the length of the stroke: Crank is stamped R15-5! Woohoo! Definitely awesome news. With the look of the head, I'd say ive got a R15A. Nothing wrong with that, they have the same specs air-wise.

I guess if the only way to tell is by the stroke since I plan on a rebuild, I'll take the head and valves off and look at how long the stroke is.

I'll get some pictures today after work, but man I hope its a R15. 23.4cfm @7.5hp sounds a lot better than 8cfm at 2hp. And my tank is 80 gallons. That will burn out a 2hp motor fairly quick I'd think.

Posted this in the wrong forum first, oops Hey guys, Jeff here. I bought an older pump in fairly decent shape for $100. Crankcase says m-1820, but no other real indentifiers for what it is. I've read possibly a R15A or R15B Champion? Or possibly a Gardner Denver? I'm not sure how to...
