Quincy 325 compressor Compressor runs for 20s then trips breaker

by Elijah
(Calgary AB Canada)

Quincy 325 compressor 5 hp Baldor single phase motor 26 amps with a 1.0 service factor connected to a 30amp breaker 220V.


I turn compressor on with no belts motor runs fine draws only 10amps, with belts on it draws 50 amps then the breaker will trip after a short time.

Any help would be great

Could be a bunch of things, Elijah.

Try pulling the intake filter and open the line from the pump to the tank.

Connect the belts and run the compressor.

Any change?

Quincy mdoel 310 valve rebuilding problem

by Kurt
(St Paul MN)

I am an air compressor newbie and am rebuilding an old model 310 that is in decent condition. I removed the valves but it is unclear to me how to dissassemble them for rebuilding. I can rotate the end of the In valves, but it doesn't appear to be threaded and is not moving off the body. I have no idea how to dissasemble the Ex valves. Help please!

Quincy model 310 valve disassembly
by: Anonymous

Disassemble the valves by gently tapping the valve disk with a drift and they came apart quite easily.

For the IN valves lower the drift throught a central hole in the valve bumper (body), where it rests on the valve disk, and then tap it apart to get the valve seat to separate from the valve bumper (body).

For the EX valves, slide the drift through the vent slots on the side of the valve bumper (body) so it rests on the valve disk, and tap it to loosen the valve seat from the bumper.

You may have to insert the drift through different slots to assure the seat does not get cocked in the body during removal.
