(Wading River,Long Island)
Air is escaping from the vent in the front of the governor casing.
It seems to be fed from the tube that runs from the outlet of the high pressure piston that runs to the storage tank.
There is a tube connection to the outside of the governor casing from the top of the discharge port of the hp cylinder.
I removed all valves on the piston heads,disassembled,cleaned and re-installed..Still have the same problem. This is a Speedaire 3Z180 Champion dual stage compressor pump. The ID. at the pump base is: NR-14-6A.
Any suggestion would be appreciated.
Thank-you, Allan Ryan
I suspect the problem may be a leaking tank check valve, Allan.
Please see the check valve page on this site for complete information about how this component works and how it prevents air leaking from the tank out the unloader valve when the air compressor is off.
If that isn’t the issue, please add a comment.
