CAC-4003-1 Air Compressor Pump Twin Cylinder Oil Lubricated

The Sears Craftsman CAC-4003-1 Air Compressor Pump was manufactured by DeVilbiss Air Power Company for many years on their line of twin-cylinder oil lubricated air compressors.

This CAC-4003-1 Compressor pump came in both a 2 7/8 Inch Bore and a 2 3/4 Inch Bore Pump and was used on many air compressors manufactured by DeVilbiss.

If you have the 2-3/4 inch bore, the piston rings are no longer available and the 2-7/8 inch ring will need to be filed to achieve a .002 ring end gap.
