Dave in looking through your pictures, I see that you disconnected your leveling valves.  I assume that you have had this modification in place for a while.  I am considering the same thing and would like your view on how it works without the leveling valve.

Tom
I already had firestone ride rite air valves in the dash.there were only hooked up to the front.My leveling valves were shot so I decided to hook up the back and try it. It seems to work well other than I don t like the exposed plastic line under the bus. Also I will probably change them to3/8 " lines to air up faster.
It takes a while 10 minutes to air them up but they hold air well and takes less time for the rest of the system to fill up.

Dave5Cs,

I eliminated the height control (leveling) valves on our former 4106 and installed air ride seat valves too. I ran the air lines in gray plastic electrical conduit under the bus to protect them. You might try that.

Good luck, Sam

Dave5Cs, what about maintaining the "correct" ride height, is that a problem?

I think that the bus, in it's first life, would have widely varying load conditions, people on and off, front, back, everyone on the shady side on a hot day, so side to side and height leveling was quite actively used.  As we use the bus the load varies very little in comparison, so setting the height once, noting the pressure and going back to it to travel is quite acceptable.  You could even set it so that you were level on the crown of a typical road that you drive on.

BTW, running the air lines under the bus floor was an epiphany for me.  My bus has ribbed aluminium floor, and I could so easily fabricate a piece of aluminium to rivet on between two of the ribs, end up with a nice wide, 1" deep chase to pull all sorts of stuff through.  Way easier than tring to fish it through the inside of the bus!

Brian great idea. I can put aluminum over the space they are in.
Ride height I know now that it is at ride height and comfortable at front 75 psi and rear 80psi. I leave it there unless parked on a hill and then adjust slowly to level.
