BronsonA2150 Posted Tuesday at 08:29 PM Share Posted Tuesday at 08:29 PM Anyone know where air supply comes from for 5th wheel slide? Mine has been unhooked for some reason and I have a cut air line stubbed out of firewall that appears to be the supply. Tracing that line back from the switch valve it first hooks into a valve behind the dash and when I blow backwards through it the supply air gauge goes up. I can’t remember the name for it but that valve it hooks into looks like a valve I’ve changed on top of the axles on my hopper bottom before. Just wanting to see where it is supposed to come from before I go hacking Quote Link to comment https://www.bigmacktrucks.com/topic/75043-94-ch613-5th-wheel-slide-air-supply/ Share on other sites More sharing options...
Joey Mack Posted Tuesday at 09:07 PM Share Posted Tuesday at 09:07 PM Pull the trolley brake and flip the 5 th wheel switch to see if that part is connected right. It should leak air. Then you can trace it.. it is connected to the trolley brake.

Joey Mack Posted Tuesday at 09:34 PM Share Posted Tuesday at 09:34 PM If its the short 1/4" line, about 4+ inches long, may be with a small group of lines, it is an exhaust line. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75043-94-ch613-5th-wheel-slide-air-supply/#findComment-567176 Share on other sites More sharing options...
