Air Bag Valve
 
1 Attachment(s)
Last two times I've started up the coach the right side air bags didn't inflate. I used the jacks to take the weight off that side and fiddled with the valve (pic attached I hope) which controls the ride height I think and got them to inflate. I didn't notice any unusual leak down while driving after this but had noticed this particular valve recently continued to bleed air long after the engine was stopped.



So I'm thinking the valve is bad. Question is what exactly is it and a source? Oh and btw when frustrated trying to leave campground and sitting in the mud the last time I broke the rubber boot connecting it to the rod attached to the axle!! :sad: Now attached with duct tape and zip-ties.


Any advice appreciated on how to proceed but we are back home and stationary so have time to work it out.

the ride height valves are available at any truck supply store. They are commonly used with big rigs.

Remember that the ride height is specific for your coach year and model. If the height out of spec with what it is suppose to be, it going to be putting stress on the drive train and other components. If too low, the tires can rub on the coach structure, doing lots of damage.

Your photo is not displaying correctly on my screen. But I think you have thr Haldex/Firestone valve.

Very good point on the height. I checked it before rolling the wheels and at every stop.

Don't know what's up with the pic. I was ok before uploading but apparently something went haywire.


Thanks for the links. I'll check and see which one works.

Update: Finally got under the coach and removed the height control valve. It's a Hadley and appears to be the 450 series. Will attempt to source locally but may end up taking a chance and ordering online. Thanks for the help.
