I've attached a document from Quincy that should certainly help you identify this pump. It's tough to say exactly what the ROC# is, unless you see a "7" somewhere on the crankcase, which would confirm it's a ROC# 7 pump.
This pump is from the 1950's with a ROC# that low, so most likely rebuilding it won't be worth it.
There is a 7 stamped on the flywheel end of the crankshaft. Believe it or not, the bottom end looks really good. No rust or slack that I can see. I drained the oil, pulled the inspection cover, and pulled the valves out of the head. Valves are nasty but crankcase looks good. I'd like to rebuild the top end and just see how she does. I love old American made equipment! I did test run this compressor before I started tearing it down and it was making air with no knocks. Thank you for your help and replies.
Thanks for the document. I've printed it out and everything looks to be the same as my pump except on mine somebody routed one of the unloader lines from top of the unloader to the tank
That's great to hear, I completely agree regarding the good 'ol American made equipment and this is one of 'em! I'd contact Quincy to find a dealer (if you're not sure where they're located) at 251-937-5900.
