Removed old parts, installed new ones. The overload switch, first, remove four screws that hold the instrument panel to the frame. It\'s blue with gauges on top. Lay compressor on its back, remove four nuts. Remove compressor from frame. Unscrew air filter, set to side. Removed four allen screws that hold on plastic shield. Loosen nut tha t holds overload switch. Make sure the two wires that are on it go to the same terminal on the new one. There is very small writing on the switch. Put it back together in reverse.
