B5900 Air Compressor Pump Gasket Kit #05C185

Complete gasket kit for the B5900 Air Compressor Pump. Includes the head, inner valve plate, cylinder, crankcase, oil pan, bearing cover, aftercooler and intercooler gaskets.

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.
