Nice Drawings
Is the bracket for the side without the cone the same or a little shorter and did you say somewhere the cone needed to face forward on both sides.

My question to this remarkably simplistic and economic solution deals with bag rotation. Since the bag does hotdog a bit, and without going out and looking at my bags how would you do a 180 bag mount rotation? Looking at the drawings one hole is 1/2" and the other 3/4", if both were 3/4" would that allow the bag to be rotated in relation to the mounting plate?

Skip,
Which drawing isn't true? The Firestone drawing, or the one that I did for
Mark?
Since you are able to look at the bag, I have some questions.
Mark's idea was to be able to make both adapters identical so that there
wasn't a fore and aft version and could be swapped during a bag change. If
the round plate on the cone end is reduced in diameter, would the same
diameter also work on the opposite end? What diameter would work well for
both ends?
Thanks,
Guy in Sacramento

The firestone is wrong the drawing makes the metal plate and cone look the same but the cone is 1/2 inch wider. the metal is 9.0 the rubber is only slightly wider than the metal in a zero pressure state, like sitting on the bench. Have to look at it tonight when i get home and see how much meat is in the end of the cone to see if a 9" plate would work.

If you look at the Firestone site and the drawings, the 2 drawings below the bag
drawing make total sense.
It shows the piston view having a diameter of 9.5", apparently the piston in the
bag drawing above is not drawn to scale.....if you scroll down, it shows the
piston being wider......I would make that plate 9.5 with a rounded edge in case
the bag goes over it.
The other drawing shows the bead plate as being 9.0", so I would make that plate
9.0" with a rounded edge.

Mark,
I laude you and Guy's work on this, however, I have a comment.
When the coach is fully down I note that the bag wraps over the end of the bag
with the bead plate. The diameter of the mounting
plate in the picture is 9 1/4". If you look at the drawing of the bag:
http://www.truckspring.com/products/Firestone-Reversible-Sleeve-Air-Spring__W01-358-9294.aspx
You will see that the OD of the bag is 9.12 in and OD of the bead plate is less.
It also wraps over the top of the piston end of the plate when it's fully down.
I would suggest that the OD of the steel mounting plate for the bead plate end
be reduced to the OD of the start of the bead plate
radius.
The drawing doesn't make 100% sense to me. If you note it shows the OD of the
bag to be 9.12 inches and the bottom of the piston
appears to be smaller than that. However, the "Piston Bottom View" gives the
dimension of 9.50 inches.
I would suggest that the OD of the steel mounting plate be a bit smaller than
the OD of the Piston Bottom.
Furthermore I would suggest that the edges of the steel mounting plates have a
gentle radius so the bag is not worn or cut when it
rolls over it.
Regards,
Rob M.

I have uploaded the airbag mount drawings to the photo site. The link is:

Special thanks to Guy Lopes for doing the drawing. He did a great job with my
sketchy discription.

If the cone is solid Guy, I think it would work. If it's not solid, you'd have
to see how a 9" plate is structurally supported first.

The drawings that I have seen on Firestone's site, and here:
http://www.truckspring.com/products/Firestone-Reversible-Sleeve-Air-Spring__
W01-358-9294.aspx
show 9 1/2" on the cone end and 9" on the air inlet side. Do you have a
different drawing?
I'm still curious (and without a bag to look at myself), do you think that a
9" plate will work on both ends?
Thanks,

The cone is not solid but I can't remember what the ribbing looks like, trying to get someone to send me a picture from the house.

I did grind the plate smooth when I installed them for the final time. the one on the cone end does not quite roll over the end plate but you are correct on the filler end. It only does that when the bag is deflated but I see your point and will add that to the comments. Good catch thank you.

just for info: the flange on the outside is 1/2 " and the little ribs are 5/8"
My son helped me post the photo, he posted the photo instead of the link to the photo before i knew it, hope it doesn't cause a problem or get me in hot water, he assured it won't eat up any of the forums memory
and a WOW to the Cosworth Vega toad I had a 73 Vega GT when I was a kid was pretty good till I had to take a torch to the frame so the headers would fit, couldn,t keep it aligned after that.
