Title: MCI-9 Manual Leveling
Post by: Danny1 on July 01, 2009, 08:26:10 PM
I have a MCI-9 with a manual leveling, four individual gages from 0-160psi. (No auto leveling)

Need impute how to level the bus left to right and ride height.

Bus either bottoms out or bounces like a basketball.

Thanks,

Danny

Danny,
   Pressure required will depend on how your bus is set up (actual weight on each corner). Best way is to check clearance between axle bumper and frame and adjust air pressure to maintain factory spec shown in your manual.  Jack

Danny,

Is the auto leveling for going down the road completely removed? 

Most manual leveling that I've seen is for being parked and then switched back to auto for driving is why I asked.  It may be as easy as switching it back.

I've read that a pressure that results in fairly normal ride heights is around 45 psi in front and 65 psi in back.  maybe put those pressures in and see what you get.  Obviously loading will impact pressure and ride heights.  The stock setup for MCDI was to have the fronts connected together and always sharing the same pressure, while the rears had separate ride height controls.
