Frame Gasket, B4900 / T29S Pump #048B58

Old Part Numbers: 6231645200

Gasket in between the crankcase and the cylinder. B4900/T29S air compressor pumps.

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.
