Looked at the solenoid, have a chopped O ring. Hopeful for a simple fix.
Want to put a pressure gauge on the comp. May add a tank and make the comp come on with ignition when I rewire accessories, then just switch the solenoid. tcase will be air shifted; air horns would be nice sometimes too
There are several solenoid replacement options if needed. I do get oil contamination in the line, reading that I did suggests that really cleaning out the line can help things work as they should, but I'd figure that the gear oil on the wrong sides of the seals in the locker doesn't help things down in the diff either. Full disassembly is the only way to clean that out. I think lots of miles unlocked lets the oil weep past that seal when it's not under pressure. I didn't check the axle vent tube for restriction when I installed, that's another common means of contamination since if the diff builds any pressure it can really help oil get past that seal. I know it doesn't leak since I've let the thing sit for an hour or two locked and the compressor never kicked on - with no tank.
Still need to finish trailer wiring stuff, and I'd still like to get the toolbox deleted from the front of the deck and get a couple boxes underneath. Have some thoughts and plans for ramps as bedsides too, for tractor/atv/minitruck loading. Going to make them 10-12' long with a nested fold, probably build from 2"x.120 angle. Need to check some per-foot weights and make sure I'm not thinking of 150# ramps. I would like them to be under 50# ea so that may mean steel frame and aluminum tread?
