I hooked a 5hp motor I had lying around to this compressor that has been sitting on edge of shop since my brother bought the place 10 years ago. Motor is rated for 22 amps. I put a single 5"pulley on the motor and tied to a breaker. Pump was open discharge. Stood behind the pole when I cut breaker on to see what would happen. Was able to turn pump by hand beforehand. Made a little noise but was pumping air. Let it run for a few, but motor wouldn't start it back up even though I could turn by hand...just hummed as if overloaded. Only tried a sec. Testing to see if worth messing with. Noticed some heat on low pressure side valve cover. Motor may not be heavy enough. 30# or so. Any thoughts? Thanks!
