Old Part Numbers: K0058, K-0058, K0650, K-0650 Sears 919.16014, 91604
Includes air compressor cylinder, piston ring, retaining screw, o-ring, and head o-ring (does NOT include connecting rod / piston). Parts not sold separately.
Replacing the cylinder sleeve and piston ring usually restores compression in oil-free units. Inspect the reed valves as well, but unless the valves are obviously broken or cracked the problem is the compression ring and cylinder and replacing this kit should make the compressor run like new again.
