- The local quincy distributor is very helpful for gaskets and replacement parts: John Hinkel <john.hinkel@quincycompressor.com> NOT AVAILABLE VIA EMAIL 2021. ,
- Our compressor is old enough that he can't look up the exact parts on his computer so there is some guesswork in identifying which gaskets are correct. So far he's been on the ball.
- The compressor came on a tank from the 1960's and it is unclear whether this tanks is safe to use. The cost of hydro-testing was prohibitive, so a new tank was procured from McMaster Carr
- The compressor has a history of leaking BADLY. In June 2017, the compressor head was diassembled, cleaned, and new gaskets installed. This reduced but did not eliminate leakage. Primary culprits for the leaking were the 2 side access panels. These are made of zinc, and over-torquing the mounting bolts caused them to warp. They were straightened on the arbor press before re-installation, however, leakage is still an issue.
- The unloaders have diaphragm gaskets that are cracked, and should be replaced
