People start lining up behind my desk...oh-boy! Production has ground to a
halt, we have low air pressure! Just where ARE those compressors? Somebody
goes back and finds them, starts up the Hydro-Vane back-up and shuts down the
Quincy that's running. I told the techs to let it cool then pull the valves.
Here I see that the other two Quincys have been moved out of position and
unwired and unplumbed....hmmm. They were in the way when the guys installed the
refrigerated drier. (Way Cool!) Besides the one pump was only running less that
50%. On the bench, the high pressure discharge valve looked the worst with
carbon build-up but nowhere near what they looked like before we started using
synthetic oil. We put it back together and filled the crank case up all the way
until we could actually SEE oil on the dipstick!
A. Remember where the Quincys actually are.
B. Use synthetic oil.
C. Clean compressors once in a while, they get HOT!
D. Make sure there actually IS oil in the crankcase. (Quincy's unloader won't
work without oil pressure, no oil=no air, kinda' like a cry for attention
without damaging the pump.)
E. Buy a Quincy!

When I called Quincy, they told me not to use synthetic.

Synthetic has a different HC chain that's more likely to find it's way around
seals, rings and gaskets...unless you break the unit in for a few years on
legacy oil. I'd never go back, the valves tell the story.

Please log in for more thread options My quincy has had way more trouble.Its a tractor PTO unit that runs days on
end in winter weather. I have to tighten the belt EVERY year. Even had to
replace it a couple times. Plus, I had to clean the unloader valve out once.
Of course, the unit is only 22 years old, so its just getting broke in.
P.S. buy a quincy
