HB55 Air Compressor Pump Overhaul Kit #05A78B

Old Part Numbers: 165-0304

Overhaul kit for the HB55 in-line 2-stage air compressor pump, includes valve plate assembly with valves, gasket set, piston ring set, conrod insert bearings, oil seal, and air filter element.

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.
