Crown Air Bags
Any Crown guys know of a way to determine the air bags on a 1990 Crown Supercoach without having to remove them? My Crown has Firestone bags and their part numbers which begin with W0 is usually a sticker somewhere on it. There is also the bellows number (1T15L-2) on the side of the rubber bag itself. The attached pics was from the front bags. I don't know if the rear bags have the same number as I could not easily get to them at this time.
Unfortunately, the bellows number produces over 40 options to choose from.
I have been told that I need to remove the bag and take measurements of the upper and lower mounting plates in relation to where the air inlet and mounting stud locations are. This may result in it being an OE only type of bag.
The only Firestone number that I found for Crown was W013589432 as shown below. However, it has a different bellows number than what I have on the front.
Firestone Bellows Number:1T15L-4
Compressed Height: 6.43
Top Plate Number:3215
Top Plate Width:9.00
