I have counted more than 8 York type compressors and several rotary types in my garage...

What would a test bench need to have to reasonable check the condition of an AC Compressor ?

Thanks, Greg

Greg, that would be right up your alley. Fabricate a jig to hold the compressors, rig up an electric motor at approx 1750 rpm, a 12 volt battery with the right connector and a switch to engage the clutch, a cut-off rear connector with a Milton air chuck soldered to it for a pressure gauge to connect to, some oil to put in it to run it, and fire it up. You'll be able to check the output pressure and if you rig up a ball valve you'll be able to check the compressor for leaks with some soapy water. You will also be able to check the clutch engagement. However, the time and money put in to the fabrication would probably be better off spent on a new or rebuilt compressor. Your time is money!!

York compressors, eh?

I've always wanted to take one of those and make it into a "normal" air compressor, hooked up to a tank mounted somewhere on my pickup, so I could have onboard air...

Do I need a setup where I actually use 134 or 12.. or can I test the compressor by gauging its ability to compress air ?

Bill, my time worth money ? LOL

The Warden, I am sure you are better off hooking up one of these tire air inflators ...an ac compressor needs oil in the pumped medium for long term use as lubricant.... Greg
