    Guys,
    I'm stumped as to what is wrong with my compressor, it's a CH 60 gal upright with oil. I bought I used without a motor. I bought a brand new motor and it ran fine for a year or so. Now when i turn it on it will run for a minute to add much as 5 minutes or sometimes long enough build 125 psi. When it stops it's the pump that stops the motor will spin in the belt.

    I finally got enough nerve up to tear it apart to see what is wrong. I expected to find something that looked bad, but I didn't find anything that is even fit heavy scratch left alone gouged. The oil i drained from it was a little dark, but didn't seem to be excessively dirty.

    Here's some pictures I took.

    What do you think? I'm open to ideas.

    If your belt was a little loose before you noticed it and got hot and glazed, it is pretty tough to get so it won’t slip as the pressure is building. It could be as simple as a new belt and tension. Sometimes a little belt dressing can help make it grab better, but once glazed it likely is done.

    The cylinders and pistons look good. The crank spins free? Rods feel good? If everything looks good I am thinking the same thing about a new belt and tension. It may be that simple

    Thanks guys!

    Yes, the crank spins freely. I may just stop at TSC on the way home from church and buy a new belt tomorrow.

    I picked up a belt yesterday. The temps are to be above freezing tomorrow afternoon, maybe I'll get it put back together after work.

    I cleaned up the pulleys, mounted the pump, installed and adjusted the new belt. She ran right up to 125 psi without a hiccup. Thanks for pointing me in the right direction guys.
