Gas compressor exhaust valve leakage
by C. Bassett
(Frankford, WV, US)
In restoring a General Supply & Leasing gas powered air compressor we are experiencing severe exhaust valve leakage to the extent that the machine never reaches 90 psi (kick down, tested with an external air source, OK).
Can you give us a source for information on the proper servicing of these (3) components.
Though old the machine runs well, this is the only fault we could find in careful checking and test running.
Description: GM V6 block, one bank gas power, other bank generates compressed air.
