Help me ID a Quincy compressor pump!

[stenella]

I'm working on restoring a vintage Quincy compressor found at a swap meet - I'm not sure how the model numbers work but the stamp on the back reads X8-13 and below it is a stamped "R".

I see others with "X8" compressors around but not sure what the 13 means.

I'd like to find out the CFM and proper HP/RPM motor required to drive this, the pump is in great shape mechanically and think it'd be a great project to clean up.

Thanks! Will update with progress once I know what we're dealing with.

USUALLY, that second group of numbers is the 'Record Of Change' (ROC).

Yup. Looks like Model X8 ROC 13.

Looking on the interwebs, it looks like ROC 1-17 share major parts, as the breakpoint for parts kits is ROC 18 and up.

Page 6 of this document has the specifications for the X8 pump:

Quincy Customer Service is really good about emailing old stuff. They gave me complete maintenance and parts manuals for my '73 single stage two cylinder.

Thank you to everyone who replied! Indeed that is the ROC and I've spent the last week learning a lot about compressors.... Ended up finding a Quincy 230 for cheap and not using this pump for now. Getting my pics together of the rebuild for a new thread

hey, i know this is old, but what does the backside of that compressor look like? we moved recently and our movers damaged my compressor. i think whomever had the compressor before my used a pipe ****** and a cap (as a plug)and that was broken off but i want to be sure it doesn't need to be a vent of some sort
please / thank you

i'd consider that the front side of the compressor.
that's the oil drain.
typically a pipe plug, but you could extend it with a ****** and a cap to make oil changes less messy.
clean out any pipe remnants and run a tap through it to clean up the threads

thanks, i pulled what was left with an extractor over lunch so i can get the right size. i wanted to be certain before i plugged it.
