Darl,

I am sure Jim Shoen will echo my words. The tasks you want done are not difficult. Just so you are aware of what I would consider reasonable times you can use the following to determine if your service facility is being fair to you and themselves.

I would allow 12 hours for all the air bags. That is 1.5 hours each on average and that is ample time and includes pulling the wheels necessary to access the bags. Make certain the front air bag fittings get modified if you do not have IFS. Roger and I did his coach quite easily by adding a 4 1/2" nipple to bring the fitting towards the outside where it was easy to get a wrench on it. It requires a new straight 1/2" compression fitting and the nipple and the hose to get cut. I think we posted pictures and the procedure.

There are 3 port and 5 port valves on your coach. The critical thing to remember when changing them is they are to be leak free at all fittings (like the air bags) and this is easier said than done. Jim and I added the fittings to the new valves on the workbench instead of trying to do it while under the bus. I would guess it took me about 30 to 45 minutes per valve at the most. The fittings and hose connections have to be absolutely leak free.

My guess is 2 solid days of work and your bus should be done. They must use ample supports beneath the coach. I double up my supports and I recommend anybody that even contemplates changing air bags or Norgrens needs to do the same thing because the entire chassis is up in the air.

I am going to help Eric in about a week do the air bags on his bus. If the times are any different we will post it.
