air leak??

[Old Scout]

YUP--if you lower the jacks [using auto-level] the bags deflate first--not sure I understand what you are telling us--are you saying the bags use to stay inflated with the jacks down and now they dont??????

Well, I really don't know...I just have heard the air coming out when I parked. Didn't know the bags were to lose their air when the jacks are down..maybe I don't have a problem and that is normal..maybe I will start the rig now with the jacks down and see if the bags inflate, shut it off and see if they hold air??

with jacks down and air bags empty, I started the rig and it showed "Low Air" on the speedometer gauge so ran the rig for a while till it went away but the air bags were still empty when I shut off the engine..didn't hear any air leak.. will go out after a bit and turn it on again and see if it says air is low..

One short-coming of this forum is that well-meaning people often make assumptions about how a particular system works on someone else's coach based on how it works on theirs--sometimes this works, sometimes it doesnt. Generally speaking, the sequence of events when you auto-level with your HWH system is, upon activation [two pushes of the "on" botton], all 4 bags deflate, then HWH lowers jacks to level coach. To raise jacks, hit "store" botton--jacks are raised by springs. Once all 4 read lights go out and green travel light comes on, you can start engine and bags will air up. If you manually intervene at any point or start the engine, all bets are off as to what HWH will attempted to do or how the bags will react.

thanks, sounds right to me so will leave it as it is for a while.. has been this way for a while..front just looks a little low on one side when parked and not on the jacks..thanks to all. Mel

You may need to check your ride height is set correctly. As a quick check, park on a perfectly level pad and with the engine running check the height of the wheel arch above the ground on both sides. They should be within an 1/8".

During a recent service of my '05 40fdts, the tech found the control rod was not attached at the lower end for the height control. The grommet that holds everything in place had rotted away. Anyone know where to find said grommet?

[EngineerMike]

Don't know where to find the grommet; if it was me I'd make a grommet by cutting a round disc about the thickness of the "eye" ring the grommet goes in, then take two additional rounds slightly larger to glue together a "spool that I could punch into the center of the eye on the adjustment rod. if needed I'd put a couple small holes in the new spool and safety wire the spool in place (might also use small sip ties, but the safety wire would be more secure.

I would check with a local Haldex distributor.
