I have a CF2600 pancake, it pumps up fine and shuts off
at 135psi, then it comes back on and runs a little, then
shuts off. It keeps doing this. Any suggestions, Thanks
Chances are good it's the tube seal. ( the tube seal will only leak while pumping up )

I had the same problem. It turned out to be the check valve screwed into the tank leaking back through. It leaked air back through the compressor head after it reached pressure and shut down. I read where you can clean the check valve with lacquer thinner. I used carburetor cleaner in the spray can instead. It worked. I cut the band clamp and removed the check valve. I held the check valve open and sprayed through it both ways. Replaced and reinstalled with 2 radiator hose clamps. It now holds.

Robert's above input was great! I had the same problems. Banged my check valve w/ a wrench and the problem went away (temporarily). I am looking for a convenient time to clean it...but just in case I've ordered a new check valve. Thanks for the posting of problem and fix guys!!!!!!!
automatic shut-off Question by tony oviedo
Why won't my porter cable pancake compressor not shut-off automatically anymore?
Take the cover off your regulator and turn the torque screw two full turns counterclockwise, put the cover back on, with the compressor plugged in bleed off air till the compressor kicks in, see if it shuts off at that new psi setting. If it does, than you may increase (turn clockwise ) the same screw you decreased. Just dont go all the way tight with it. A few drops of Wd-40 on the point linkage pivot arms doesn't hurt anything either.
Can Question by Rodger
The compressor starts up fine and quickly gets to about 45-50psi and then doesn't go any higher. The pump continues to run but the psi never goes higher. The compressor worked fine this spring. I have checked the external connections for leaks and didn't find any. I assume it is a gasket or O-ring in the pump. Any suggestions on what parts to replace?
My porter Cable pancake compressor is able to hold pressure but constantly runs due to a leak some place in the compressor. What part do I need to replace?
IF you can hear air escaping from some place it is most likely a bad hose or connection. If there is no hissing sound then most likely the leak is internal. The most common reason a compressor will continuously run is from a worn out piston and cylinder. If this is the case the piston and cylinder will need to be replaced. The piston and cylinder are sold as an assembly in the connecting rod kit. The connecting rod kit is part #KK-4964 and is available from http://ereplacementparts.com.
I hope this helps with your repair!

compressor stals Question by Joe
My first attempt to repair; compressor had been running, cut on at low pressure but only ran a bit in fits and spurts with burning smell from the motor
Whenever a electrical burning smell is present you have to suspect the motor field and / or armature. The field and armature have wire coils on them that are insulated with an epoxy coating. When the motor overheats the epoxy coating melts or burns away. That is what makes the burning smell. Individual motor components are not available for the motor on this compressor. You would need to replace the motor and pump assembly. The motor and pump assembly is part #Z-A04615 and is available from http://ereplacementparts.com.
hope this helps with your repair!

PC model CF2600 type 2 pancake compressor 135 PSI (bought in 2003) that leaks thru the head. There is a small pin hole in head in a deep recessed area where the center diaphram touches it and leaks air out there. Should pinhole be there in the casting of head? Is there some part to replace to fix such as the head gasket or valve plate assembly? Thanks....

I have a porter cable cf2600 purchased in 2003, it has always worked perfectly. When I switched it on today it was completely dead. I have checked the electrical circuits from switch to brushes and the fuse and all is good. Can anyone give me advise as to what I should check next. I am totally stumped.
Hello. I have a CF2600 and had an air leak around the motor. I purchased a new connecting rod kit, valve plate, and gaskets and put everything back together. The compressor will only charge up to about 100psi and keeps running. I found another air leak under the pressure switch on what I think is the bleed off valve. I thought the check valve might be bad, but when I turn the switch to the compressor off, the leak stops and the tank holds air. It only leaks air from that small valve on the bottom of the pressure switch when the motor is on and the tank is filling up. Any ideas on what I can do to fix this? Thank you.
