My 50 year old manual is missing this info. I need where to measure from, and the height.
Thanks, Dale
If you're trying to determine the proper height for air ride, put your bus on blocks high enough so the bus won't crush you when you exhaust the air from the air bags.
Measure the axle to frame when the air bags are completely empty then when full (you have to manually operate the leveling valves). Set at 5/8 up. For example if you have 7" total of travel, set at about 4.5" up. Good Luck, TomC
As I remember it, the manual says that rear air bags should be extended to 7.25". However, if the drive train has been changed you may need to adjust that by what it takes to keep the drive shaft straight. I don't remember what the front ones are supposed to be, but that would be less critical.
Thanks All.
Dale -
The top of the bottom step in the entry door should be 15" off the ground when parked and level.
Use a carpenter's level to determine front to back and side to side while keeping the front step measurement static.
FWIW & HTH. . .
