Coleman Powermate Air Compressor Piston / Cylinder Kit #058D59

New piston/cylinder rebuild kit includes the piston/rod assembly with compression ring, cylinder sleeve, and o-ring.

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.

Note: Bearing screw must be torqued to 40-50 in. lbs. No compression usually means a worn piston and cylinder (make sure your valves are not broken by inspecting the valve plate as well.) A 30-minute repair well worth the time and money. 

Important: When installing, slide piston down into the cylinder. Failure to do so will damage the piston ring.

Part has 048-0088 marked on the rod.
