[Shop-talk] Quincy 310 compressor guru needed

[john niolon]

I’ve got a Quincy 310 roc 24 compressor that just started giving me trouble....  unloader is doing just that... and it won’t build pressure...  worked fine yesterday, today it just blew me off...literally.
Oil level is full... pressure is 25 psi.   I’ve taken the unloader apart and everything is moving freely and shows no abnormal wear... but something isn’t moving to close off the unloader, I guess...

any quincy guru’s or can someone help me trouble shoot this problem ??   I know there is a pilot valve that is connected to the unloader by 1/4” copper air line and when I disconnect it from the unloader
I feel air pressure at the unloader end of the tube...so it should be getting a ‘signal’ to stop unloading, right ???  

anyone... anyone ????
