OK, I'll check that out, although I suppose if it ain't broke... I keep it
well filled with oil and its run ok for the last 45 years. Admittedly off
and on

I was waiting, (lurking), to learn how to do this, but my little
Quincy(circa 1960) has two plug like thingies on the top of the head

thingies. Do I have valve discs that need maintenence,or some other
design? If so, do I just unscrew these things with a tie rod wrench or
such? I'm guessing if they are gasketed they might be like sparkplug
gaskets and ,(hopefully), reusable.

John, may I suggest you locate your nearest Quincy authorized parts dealer
and get a manual from them? They don't charge for them, or didn't charge
me
for mine.

Unbolt the 4 bolts from each of 4 valve body thingies from the top of the
head. Make or buy (shudder) new gaskets. It'll be self-evident.
Usually just the exhaust valve on the high pressure side gets
carboned-up. You'll know when the pump is running more than usual and it
won't get up to pressure. Mine get gunked-up once a year running 10
hours a day with a 50-70% duty cycle.

Tom,

Thanks for the help. How do I remove the valve disks to clean them?

Thanks again.

Ok, sorry...I use synthetic compressor oil from Grainger, second choice
is a non-detergent (keeps water suspended) like Shell Rotella, although
anything will do...keep an eye on it and change it once in a while.
Your Quincy will last FOREVER! You'll have to take out the valve disks
and clean the carbon off once in a while (yearly under daily use).

Hi Guys,

I am looking for recommendations and a source for compressor oil. It
is for my Quincy 325 Compressor. I went to HD and Lowes and they do
not have much of a selection and I am not sure if what they sell is
compatible with Quincy.

Thanks.

Joe...
