Looking for a DIY airbag replacement tutorial.
I have a 76' PB 26'. I have new off the shelf Firstone bags from Cinnabar
which came with the coach when I bought it in 2009. Driver side still good,
passenger side has gotten progressively worse. I have 2 new bags and want
to know if I should just replace the passenger that is faulty or just
replace both?
I would like to install the valves right at the bags to.
Many thanks in advance,
Eden in CT.

The agenda for Branson has Rob presenting on air bag protection.
If possible you may want to review before changing them out.

Rob,
I remember you showing me airbag covers at Amana last year - they're the Bob Sternfels' covers, right? Bob's coach was up for sale on eBay a while ago and in the description his grandson(?) said that Bob had some serious health issues. Do you know if he's recovered?

My son and I just replaced both airbags on our 77 Kingsley early this spring. Both new bags are from Cinnabar's new supply. They came with the metal cones so make sure you have metal cones as they are far better than the OEM plastic cones.
We jacked up the wheels using bogie plates and a stubby bottle jack using a jack hook. When we first tried to get the wheels off the ground it took a lot of jacking. It's so much better using the bogie plates. And, don't forget to let the air out of the old bags before you get the wheels completely off the ground, probably just as soon as you get the weight off the wheels. This keeps the airbags from pushing the wheels apart and stressing the shocks.
We have shraeder and shut off valves in place too which are a great help. Our auto-leveling system works pretty good but there is a small leak which we haven't found yet. Once the airbags are where we want them and the coach is going to sit for a while we shut the valves off at the bags which isolates them from the rest of the system. We also put blocks under the bogies so when the air leaks the blocks hold up the wheels. All is working pretty good considering all that's involved.
Good luck,

Gentlemen,
Thanks for the info on Bob Sternfels. Never met him, but he sounds like one helluva guy.

If anyone wants those protective bags, I have few left.
Should you need instruction on air bag installation, you can call Nick at 800-752-7502 and he will walk you through it.

Hi Eden,
I've done the OEM airbags a few times (thank you Jerry Wheeler!) and would be happy to walk you through it. I'm also in central CT and could drop by to help if that would be useful.
You need a big jack under the bogie, and a big box end wrench to get the nuts off (1-1/4" or 1-1/2" I think).
The procedure is pretty straightforward -- raise the bogie to get most of the compression off of the bag, release the air pressure, disconnect the air line, remove the nuts, squish the bag ends together to remove (might help to raise the bogie slightly more before removal).
Anyway, let me know if I can help!
Good luck,
Andrew
