Dewalt D55141 Air Compressor

[Misomosi]

I own a D55141 compressor and it will no longer compress beyond 45 psi. There does not seem to be an air leak anywhere and the motor never turns OFF. When I disconnect the power and air hoses, the tank will keep the low psi forever...it this a problem with the pump regulator?

Hey misomosi,
most likely it is your piston/sleeve assembly..it is just wore out and needs replaced..check out the breakdown on ereplacementparts.com to where it is located..[page two] part # kk-4964 .. you may want to take this in to a repair shop if you are unfamiliar with this type of repair..hope this helps?
