Brandon, To disassemble the check valves does take some muscle.  (I think there are 4 chinamen on a 4-foot bar wrench tightening these things sometimes).  You can get a kit from Doug Sapp to replace the rubber (the best kind) in the check valves.  A lot of times there is corrosion there and you may need a whole new check valve but clean it up real good.  Most of the time its just the rubber that's bad.  IAC clean it up good then I coat mine with a thin layer of boat axle grease.  (That seems to help alot on the corrosion issue).

Thank you very much!!  I'll disassemble again and get to work rebuilding.  I have the kits with the rubber washers, etc. already, so hopefully I can get them apart and installed.



Thanks again!

some of toughs air valves and cylinders have set screws that are partially covered in paint if you take them apart without removing the set screw the threads are ruined.

                  

                                                                    On ‎Monday‎, ‎November‎ ‎26‎, ‎2018‎ ‎11‎:‎39‎:‎59‎ ‎AM‎ ‎EST, Warren Hill <hill(at)doctor-hill.com> wrote:

Jill Gernetzke can also repair/rebuild them, but it takes the force of a pneumatic hammer to get them apart.

		   CJ or YAK? The YAK check valves that have been in use for a few bears are a bitch to get apart. I personally think they use epoxy on the groves. It takes a vice and a torc to get them apart on occasion. Be prepared to replace all of the guts in that case.

		   You can just send them to Cliff Coy to rebuild with Parker air system parts. They hone the case to do that.

I disassembled the T the other day and tried to take one of the valves apart but it was so hard to turn that it appears to need a vise.  I didn't know if that's normal or if I'd be tearing something up, so I stopped until I could ask.
