Hi Guys,

I got my hands on a 1972 80 gallon 2 stage compressor. The pump is a
Quincy
model 325 13. I understand that this is the compressor on their QR
series
machines. It is in great shape, has a 5 HP Single Phase Motor and a
magnetic starter. All the wiring has been removed.

Here are some questions I hope you can help me with:

What order does the unit get wired in? Is it line voltage to -
pressure
switch to magnetic starter to motor?

What kind of oil should I use?

It is missing the air filter assembly, where can I purchase a new
one?

Where would I get repacement drive belts?

My sincerest thanks.

Joe...

The wiring is pretty straightforward. Two legs of the 220 V. from the
breaker box go to the two line poles on the mag starter. You need to
identify the voltage for the starter coil. It ccould be 110 or 220 v.
One leg off the line terminal goes to the overload switches [series] on
the mag switch, then the pressure switch, then the starter coil. From
the starter coil the other wire goes to neutral if it's 120 v.,
otherwise goes to the other side of the line for 220 v. DO NOT PUT AN
OVERRIDE MANUAL SWITCH around the pressure switch. If it gets left on,
the compressor could blow up the tank and kill people. Hopefully there
is a pressure relief valve somewhere.
I have a clear drawing from a book I published that I can send you if
this is all too confusing.
