Thanks everyone for your airspring input. For the time being

I'm going to carry a few spares, but will replace everything once

we return from the west coast.

Hi all

I am posting as an X owner of an 86PT40. When I owned this bird I had the same
concerns. Little cracks here and there. They look a little scary. The best
advice I can give
is for each owner to contact an air bag mfg, such as Goodyear or Firestone and
speak to
the tech help area or ask for an air bag engineer. Once you learn how an air
bag is made
and how many layers it has, your concerns wil change direction. They are very
very hearty
little buggers. They will last beyond your wildest dreams. Try it, you'll like
it.
Carrying one of each type is good for the soul, but that's about all. Basically
they are good
until they start leaking. Damage by debris, it will not matter how old it is.

Thanks for the invite Ernie. If we come thru that way I'll definitely

look you up. We normally head west on 40, but if the weather

is bad we'll scoot down to 20 (which is a much better road).

David, I have a 1985 PT40 that I have owned for 12 years and the air bags have looked that way as long as I have owned it. When I bought the coach 12 years ago it had about 100,000 miles on it, now it has about 160,000. I am not shure but I wonder if the bags have a thick outer protective layer that we see cracking on the outside and the actual bag sealing the air is a thinner moreplyable rubber on the inside?

I was inspecting the coach the other day and noticed
that all my airbags are checked and cracked, similar
to the appearance of a dry-rotted tire. The bags are
7.5 years old. Anyone have a feel for how long bags
should last, and how severely checked they can become
before replacement is necessary? I have visions of
installing new bags only to find the same checking one
year from now.

I note that I've twice had competent service providers "carefully inspect" the condition of my coach, and neither have indicated any concern about the air bags. They don't look horrible, but do have some checking and cracks on the outside. I take it that it's normal for the age of the bags.

While I have no way of knowing (I'm at least the 3rd owner of this coach), I doubt that any of the POs had the air bags replaced. The immediate PO never mentioned air bags, and the (incomplete) set of receipts he provided don't mention them either.

As other's have pointed out, there does appear to be an inner liner

built into today's air springs. I copied this following from
Firestone's

"Airide Design Guide":



"An air spring is a carefully designed rubber and fabric flexible
member

which contains a column of compressed air. The flexible member itself

does not provide force or support load; these functions are performed

by the column of air. Firestone air springs are highly engineered
elastomeric

flexible members with specifically designed metal end closures. The

standard two-ply version is made up of four layers:



(1) Inner Liner. An inner liner of calendered rubber.

(2) Frst Ply. One ply of fabric reinforced rubber with the cords

at a specific bias angle.

(3) Second Ply. A second ply of fabric reinforced rubber with the same
bias

angle laid opposite that of the first ply.

(4) Outer Cover. An outer cover of calendered rubber."

I dont think the bags on our bus are a bag in a bag its just one bag.
The cover inside and outside are the protective rubber keeping the
chords from the elements. Every rally I attend all you see are old
bags, something should be done. Even the description below is
confusing because ;a fabric is woven and ;bias is orientation at an
angel. if a fabric is situated on a bias , the angle is repeated
every 90deg. how could you arrange the second fabric on an oppisite
angle?

I need to go to a junk yard with a knife and check this out

They're trying to say the cords are arranged in a herringbone style.
