Ingersol Rand EP-15U Suddenly Locks up?

Older ep-15u Runs normal for some time,Pressure is good, Loads and unloads fine.


Suddenly seems to lock up on the air end. Belts slip and squeal.

Shut it down and restart it may run for hours before this happens again.

Shaft seal looks good no oil leaking on belts.

I'm thinking belt tension -

Is the motor plate close to and maybe bottoming out? When was the belt last replaced

Other than the squeal, noticed any other noise?


Good luck.
