Anyone in the Rockford Illinois area that can help a newbee in trouble? Lives in Madison WI. He bought a CMC in Michigan and got as far as Rockford when a bag went down. State patrol made him pull off and coach is at an RV dealer. I told him to call the RV place and tell them not to touch it. Then get a emergency air bag inflation kit from Jimmy K., jack it up, install the kit and air the bag up. That will get him home, but he is not real familiar with GMC's yet and may need a little help. Anyone available?

You can use a piece of threaded rod 18 inches long. Over each piece of rod is a one inch steel pipe 15 inches long. At each end of the threaded rod is a two inch washer, lock washer and nut in an emergency. It would ride hard and I would not go far using this system.
It seems like either you have a leak in the system or the bag has gone out. If the air bag is good then a sharder (sp) valve can be installed and pump up the air bag. I care them with me since I had leaks in my lines and the seals went out in the compressor system. Both easy to fix at home but not on the road. I carry a spare air bag all the time since mine air bags are not long for this word.

Jimmy K or Jim Bounds can get you new air bags over nite if necessary.

How well does he know mechanical things??

If the bag is just leaking, thats one thing but if the system is down, a new bag wont help. Does the opposing bag air up?

I was thinking the same thing, threaded rod bolted on. I think there is a severe speed restriction but it would get him home....

I am in Waukegan, far East side of the state, he is mid state if he is near Rockford. I would guess a good 2 to 4 hours drive for me. I am not the best mechanically inclined person but I know some things. If he needs to see a face, I could go....

Larry, It is 12:30 AM. If you are still up call me at home with additional details. My number is on the black list. It is 140 miles up there and I would rather fix this tonight or very early in the morning. It is in the 90's here during the day with very high humidity so EARLIER IS BETTER. Outside temp right now is only 74.

Ken and others,
I talked with him in some detail. It appears that he is fairly mechanically competent. He had that bag replaced before he left Michigan and thinks that the leak is in the system, not in the bag. That is why I suggested the emergency airbag inflation kit. Other bag has aired up just fine, and pump runs continuously. He is at home now, waiting for a call from the RV facility, and plans to call Jimmy K. this morning. Depending on when the kit arrives, he will likely be working on it either Saturday or sometime next week. Is that kit available locally, so he would not have to wait for it to come from California?

I honesty had not thought of the threaded rod, but would not be a bad idea to have it along in case it is something related to the bag. Stand by, I should be able to call him sometime after 8:00 this morning.

The simple thing to do is remove the airline fitting to the down bag and the other one, too, replace them with adapters and a Schrader (tm) valve (looks like a tire valve in brass), then air it up with a compressor. All the parts needed will be found at a big box or M&P hardware store. Be sure to get some penetrant to get the old airlines off.
Good luck.

sounds like maybe the supply hose on that side came off or split since the compressor runs all the time. the other side isn't down so it must be all connected there. he should trace the hoses from the compressor valves to the air bag.

What diameter should the threaded rod be? What diameter should the washers be?

I may carry them just in case..

Thanks, Dave

I'd try the Schrader valve first. I got the proper size 1/4" ones with no adapter needed at the local Ace Hardware. He should be able to get one at his local Ace or an Ace between there and Rockford.

The day after I bought my GMC, 1/2 way home with it, I couldn't figure out
how to raise the right rear. Nor could I find a Shrader valve at the
available locations in Bogalusa, LA. I wound up with a 1/4-1/8 reducer and
a 1/8" pipe plug. I had to use a cleaning nozzle on an air hose to inflate
the bag, then insert the plug before all the pressure escaped. It took a
couple of practice tries, but I kept enough air in the bag to get me back on
the road.

After I had my coach for a while, I found one of the emergency bag repair things in one of the storage areas.

Well, I talked with him again this morning. He called the RV place and they said that they would bring the coach in this morning. He passed on the information about the inflation kit, and made the decision to let them look at it....sooo...lets just wait a little and see what happens. I'll be in contact with him later in the day again. I also passed on a lot of information about Web contacts. He said he will be joining the forum soon.

Hi All,

This is Tony, I'm the actual newb that Larry posted about. Wow, you guys really rally around someone who needs help fast!

With the advice here I'm feeling confident enough that I can get it patched up without the RV service center. I just called the RV place back. Had to leave a message for a return call but I think I'm going to tell them not to even bother bringing it in to look at. I'll head out tomorrow morning and try the direct Shraeder valve first. I've got an infiltration kit on the way from Jim K. too in case I have problems with the direct valve. If anyone knows the exact size for the fitting on the bag that would be great since I could get those parts tonight.

I'll keep you all posted as it develops.

Thanks!

-Tony

Hey Tony, welcome aboard. Sorry you found us this way but glad you are here. Great bunch of fellas here who are always available to help. It is not unusual for folks to drive 200 miles plus to help a stranded GMCer. You called the right person, Larry. He just helped a stranded GMCer last month and I think it was at least 200 mile drive for him. Keep us posted on what transpires. We have a big gathering coming up in late Sept. down in Du Quoin, Il.

Just got a call from Steve S. He offered to help this afternoon and he's from Palmyra, WI so he's pretty close to the GMC. Inflation kit has been ordered as is on the way.

I called Larry and got Tony's number. I am probably the closest one to Rockford and Mad City. Tony and I will meet up sometime later today. I'll be taking a floor jack, tools, fittings, 12V compressor (the HF valvair clone) and a spare bag.

We should be able to git'er done. If not you blacklisters may get a call.

That's what it's all about. Without the newbies it's just a matter of time until the coaches we love fall apart into discarded derelicts that no one knows anything about.

In other words man, you're GOLDEN!

Just go to Ace Hardware and get the right size schrader valve for $3.00 and forget the brass adapter shown in the photo.
