Coleman Powermate 130/165 Pump Air Compressor Gasket Kit #058D81

Includes all gaskets to rebuild the pump: head gasket, cylinder gasket, oil pan gasket, and bearing carrier gasket.

If the compressor pump doesn't seem to pressurize as quickly as it should or is leaking in between the head, valve plate, cylinder, or crankcase while running, there's a good chance you need to install new gaskets. You can spray soapy water on the pump while it's running to inspect if there are any bubbles forming, which would indicate a leak.

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