I got my hands on a 1972 80 gallon 2 stage compressor. The pump is a Quincy model 325 13. I understand that this is the compressor on their QR series machines. It is in great shape, has a 5 HP Single Phase Motor and a magnetic starter. All the wiring has been removed.
Here are some questions I hope you can help me with:
What order does the unit get wired in? Is it line voltage to - pressure switch to magnetic starter to motor?
What kind of oil should I use?
It is missing the air filter assembly, where can I purchase a new one?
Where would I get repacement drive belts?
My sincerest thanks.

It should use a regular 1" air filter, available at Grainger or any air compressor repair outfit. Try your Yellow Pages.
On my Quincy I had to replace the belts -- it took a matched pair of B47s or something -- and I went to Grainger and asked for a matched pair and they told me they are all matched nowadays. One belt was however slightly longer than the other. I figure the short one will soon stretch out. But if I had to do it over I'd look up "power transmission" in the Yellow Pages and call every place looking for a deal. Those damn belts cost waaay too much at Grainger. Then I'd go to their will call and make the clerk bring me ALL of the belts in that size and hand pick the two closest in length. If you're going to spend $40 on 2 belts, you should get to pick. - GWE
The compressor is hopelessly broken, I can relieve you from it for $20. :) Just kidding.
Have you tried the obvious, calling Quincy and checking out their website. They may be able to send/sell you some manuals and may give good advice. I recall buying a used dental compressor, which was leaking air. I called the manufacturer, they gave me some good suggestions, I was able to download manuals etc. The problem was a tiny hose leading to a pressure switch, that simply fell off. Simple messing around with a screwdriver and thinking logically did it.
Also, you can talk to the motor manufacturer. Open up the pressure switch box, the motor wiring box, and see what you can find. See if there is a relay of some kind somewhere.
Your task is not that complicated. A few hours of working and a few more hours of thinking should do it. Would be nice to make sure that you have a on/off switch right on the compressor, when you are done.
