M35A3 air shift problems

[lonegunman]

I have an A3 with a bad air leak on the front axel solenoid in the cab. Both plastic elbows were cracked and I replaced them with suitable brass ones and the in and out air lines are snug and leak free. The valve is apparently the problem. It has a pressure relief hole directly behind the toggle that blows air constantly, slightly less when engaged. Bad enough that it drops my brake pressure 30-40 lbs at the guage.

Where can I get the solenoid?

That is just a standard air switch, all most all mv parts suppliers will have one, also that switch is used in the civi world, any truck parts house will have it or one very close to it.

Didn't find it on any of the usual parts suppliers. NAPA on the other hand, had one on hand for $32 bucks. Haldex p/n KN20001

Probably a bit late (if you already found one)... but this thread has all the info you needed...
