Cylinder head clean up valves rebuilt test running final test run of quincy 325 air compressor. I called Quincy and they sent me a full set of manuals on the 325R for no charge. Dallas Compressor also has a cut away of a 325R but the manual is better for understanding the theory of operation., 10:48 PM #8.
I like old machines and tools. You might have seen the build on the 1947 South Bend.
Along those lines, I have been looking for a large shop air compressor and I came across this.

Quincy 325 Pump
It came with a 10hp 3 phase motor that I can't use and I took a gamble when I bought it because I never got a chance to see it run. My plan is to get it running and put it in service in my shop. I'm tired of waiting for my little 2hp compressor to catch up.
