I want to build myself an air compressor because my dads one in our shed is about 60 years old builds pressure slowly and i cant afford to buy a new one my idea is to take a AC compressor out of my parts truck and put it in place of the old pump. But i dont know how these work, i tore one apart that didnt have any freon left hoping it was just like a small engine but found no cam or valves exept some valves that i have no idea how they werk. I thought i would tack weld the pully and flywheel together and leave one hose open. Is it possible to do this and can someone tell me how!!!
The compressor may have had reed valves. There are tech papers around on how to set up a York type piston compressor for an air compressor. Try the search function here also for more info. I have had an old York compressor setup for years. You will need a filter on the inlet side to keep the dirt out of the compressor. You can just tack weld the pulley to the clutch. You MUST have a safety blow off valve plumbed into the outlet side of the compressor. You can buy these at local air tool supply stores.
I had a ford piston-type compressor rigged in my IH PU until recently, as it is down for engine rebuild. Needed air, so mounted it and a delco alternator and small garden-tractor battery to a 9hp engine off a dead generac unit. Uses a standard pressure switch to control the a-c clutch (plus yes, a pop-off safety). The unit now is my shop air, and can double as a jump-starter.

I'd suggest you take the old pump off the old air compressor and find the grubbiest looking air compressor repair shop in town. Even though it's 60 years old, you still stand a good chance of getting replacement parts and they probably won't cost that much. Likely all it needs is new rings and valves & a fill of fresh oil. If it costs you 30 bucks and lasts another 60 years, call it a bargain.
