Remove spark plug(s) on the motor and the head of the compressor
if they are both stuck, generously apply Kroil or similar release
agent. *Allow to sit, then attempt turning the flywheel again.
Look into getting a long cheater pipe to use on the flywheel(s)
without bending or hurting it.

Another common method of getting the rings loose is Coca-cola.

I attempted to post this earlier but it has not appeared. *Hope

doesn't pop up twice.

I recently bought a military surplus 2 stage Curtis-Toledo
compressor
driven by about a 12HP B&S engine.

I cannot get the compressor to turn over by turning the
flywheel. *The
oil in the compressor and the engine is brand new. *I don't know
why
the military auctioned off the compressor.

I'm wondering if it got water in it or something. *How can I get
some
light weight oil into the cylinder? *If it's toast is a rebuild
a
major big $$$ undertaking?

Thanks,

Dan and everybody,

Indeed I have already separated the engine from the compressor. I
removed the protective cage from the belt drive and removed the
belts. Prior to doing that I thought that the Briggs & Stratton
engine was icky although it did turn. After removing the two V belts
it became clear to me that the motor is entirely free. The belts were
simply slipping on the large compressor fly wheel.

Is there a way to get oil in there without removing the head? My
problem is that I don't know anything about the innards of
compressors. This appears to be a single cylinder 2 stage compressor
good for 175psi at 15 cfm (if my memory serves which often doesn't).

If I get the thing to turn freely does this imply that it's "good to
go"? Or is machine work called for?

Thanks!

V
