I've had this 310 for about 5 years. Got it new and right out of the box, had blown head gasket. Always had problems with the unloader valve bleeding air while running. I put a 3 hp motor on mine and determined the max speed and bought a pulley for that RPM.

Hi, kind of new here.
Am I missing something or can this small motor run directly off the
pressure switch? Don't see the pressure switch rating.
I have a 310 compressor too. Put an oil filter on it by replacing the oil pump end with one from a junk 5120 compressor.
I found the "pen" type did not indicate voltage on a wet romex. Tried it several times but would not detect the presence of voltage on a known hot wire.
Most blower motors I see have a receptacle fitting where a plug is moved to the desired speed. Usually mounted on the motor. Mine came from Grainger and has 5 speeds.
