I have a Craftsman “Paint Sprayer Air Compressor†that has suddenly started to squeal whenever the motor is running. I’ve done a reasonable amount of troubleshooting and adjustments over the 20 plus years I’ve had the compressor, but this is a new one.
The motor turns just fine and the ribbed drive belt wants to go, but the compressor pulley hesitates, causing the belt to give off a loud squeal. After a second or so, the compressor pulley will start to rotate, but the belt is still slipping and chirping. This slip/chirp scenario lasts through the cycle.
The compressor oil level is fine and I can turn the compressor drive pulley by hand without undo effort. The belt tension feels reasonable and there is no real adjustment for tension, save for shifting the motor, anyway.
I welcome any suggestions as to the cause and cure of this annoying issue.
