Air leaking inside shroud on c005 type 3

SOURCE: compressor runs and runs but only builds 40lbs pressure

At the web address below you will find a parts list of your compressor. The most likely problem areas are the tube seal and the piston/cylinder. The tube seal seals the discharge tube to the head of the compressor. It will fail over time and cause the problem that you have. (only costs a few dollars) The other problem that you could have is a worn cylinder. Your compressor is oil free thus the piston ring is made of silicone vinyl and wears depending on conditions at the job site. Heavy dust/ dirt will shorten the life of the unit. With unit unpluged and covers removed, push the piston to top of stroke and examine upper portion of cylinder. If you see groves/scratches install cylinder kit. (cost around 39 dollars) In most cases I would replace both the seal and cyl kit. These parts are also available at your local dewalt service center or on line at dewalt.com. The folks at dewalt are very helpfull. Good luck with your repair and email if you have more questions.

The compressor will not auto shut off until it reaches the preset pressure which is usually around 100-130 psi - your problem is leakage of air from the oil filler cap suggesting that you have a failed internal valve.

Check the head gasket. Mine just did the same thing. Mine was blown between the two chambers on top. It's very thin right there. I went to the auto parts store and bought some gasket and made my own for about $6. It's up a working great...finally. BTW the gasket kit is on back order right now at Sear's parts website. It appears we aren't the only ones with the problem!

Locate the piston housing and remove the outer plate 4 screws
then tap on the next plate and when you remove it ( its the reed plate) you will most likely see a hole in one or more of the reeds
I am not technical but I have the same peoblem and I am trying to replace the reed plate on mine when I saw this. Good luck

I have same problem with my PC2002 type 3 AC and come to find out after removing the know for the regulator, inside there is a spring(remove it),underneath is a seal with a nipple in the center that is used to let the air though. It is made of plastic(so mine broke).Tough job is finding that seal.
