1. Pressure switch: The pressure switch may not be shutting off the compressor when it reaches the set pressure level. If this is the case, the switch will need to be replaced.
2. Check valve: The check valve prevents the compressed air from flowing back into the compressor pump when it is not running. A malfunctioning check valve can cause pressure to continue to build up, even when the compressor is idle. A damaged or worn-out check valve may need to be replaced.
3. Piston rings: If the compressor's piston rings are worn or damaged, air can leak past the piston and cause pressure to continue to build even when the compressor is idle. In this case, the piston rings will need to be replaced.

Tap the bolt of the puller while you tighten it, spay some penetrating oil on the shaft and leave it for a while and try again. If that is unsuccessful, apply a little heat to the flywheel and try the above again.

Hi rich, My name is John. Welcome to FixYa. Turn the screw one turn counter clockwise while pushing inward. Thanks for choosing FixYa....John

You can use universal pilot valves and throttle control. Shop on ebay or www.grainger.com. Look closely at the fittings that are required to fit a different valve on your compressor. Most all pilot valves work the same however there are hundreds of fitting combinations. The throttle control is easier because they usually all have 1/8 thread into the pilot. Universal parts cost much less. I would suggest taking your compressor to a shop that specializes on air compressor repair and they could suggest what pilot would work best. Good holidays

there should be a gasket and up read valev and plate kit for that pump. call nothstar
