Title: ride height on a 102c3
Post by: sledhead on October 23, 2013, 04:06:07 PM
I was looking in the book for the ride height and I found 15" on the front air bag and 8 " on the rear air bag . Now I tried it on the coach but the front end is so high it took 110 lbs to get to the 15" so if any one can confirm the correct measurement I would appreciate it .                  thanks    dave

I have no idea if that's correct or not.
But I can tell ya ALL the buses I have ever been around that had air bags took at least 90 lbs before the suspension even started coming up. So 110 lbs may not be far off!

Hi Dave,

I'm not sure.. I never measured that before! 15" from the skirt rail to the

ground does sound about right. Tomorrow I will be prepping my coach for

a trip and I will grab a rule and let you know.

A casino here always used 10" front and rear for a better ride so they said

If I remember right on our 96A3 & 102A3's we used to do 12" now that I think about it. (that was from the bottom of the side of the bus to the ground iirc, but that was a while ago!

Thanks guys     on my book it shows 15 " on the front air bag , 8 " on the rear air bag and  when I aired it up to the 15 " height it is way to high ( about 4-5 " higher from ground to bottom of the rail in the front then the back of the bus . So I think my book is wrong and 11- 12 " looks much better . How about a fast easy height measurement from the ground to the belt rail at the floor height ?             thanks  dave

On any air suspension vehicle, if you're not sure of the ride height, you can figure it out by putting the bus up on blocks, so when you deflate the air bags you'll not get crushed. Once the bus is up on the blocks and with full air pressure, disconnect the air suspension ride valve connecting rod to the axle. Pull the rod down to deflate the air bags all the was down on the axle bumpers. Measure the body height. Then push up the rod to fill the air bags until they are full-you can tell when the air bags stop moving. Measure the body height again. Set the height at 60% up and you it'll work just fine.

Unlike what everyone thinks, the higher the air bag, the softer the ride will be since you'll have more air in the air bag to cushion the bumps. Lower ride height will be more bouncy. Good Luck, TomC
