Base Gasket, B5900 Pump #05C195

Gasket for bottom oil pan of air compressor pump.

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 any bubbles are forming, which would indicate a leak.

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