DeWalt Air Compressor Pump Overhaul Kit #09B727

Overhaul kit for the 3-piston 040-0353 air compressor pump used on DeWalt and Porter Cable units, includes valve plate assemblies, gasket kit with oil seal, piston ring set, and air filter elements. 

If you have a sudden loss of performance, if air leaks out of the intake filter, or if the compressor just isn't performing like it should, order this kit. A loss of pressure or slow pressurization is usually caused by damaged compression rings or gaskets and/or damaged or sticking valves.

Remember to tighten the bolts down to the proper torque specs as noted by the manufacturer.
