CHASSIS INFORMATION
DIPLOMAT 2004
NOTE: Drive shaft angle is affected by the suspension ride
height. Improper drive shaft angle can damage suspension or
shorten the life of universal joints. Shock absorbers and air
springs are in travel centers at proper ride height.
To Adjust the Suspension Ride Height Begin With:
• The motorhome on flat level surface.
• Air system fully charged.
• Suspension at normal ride height.
Start by Checking the Distance in the Front:
1. Measure the distance between the lower air bag mounting plate and the
upper air bag mounting plate of the air springs.
2. If the measurement is off, loosen the adjusting lock nut at the eccentric
slot on the valve.
3. Move the plastic arm up to raise suspension height, this will inflate the
front air springs. Move the plastic arm down to lower suspension height,
this will deflate the air springs. Make adjustments in small increments.
4. After obtaining the specified distance, insert a 1/8" or 7/64" inch twist drill
bit into the plastic arm and valve body. This will center the travel of
internal piston. Tighten adjusting lock nut between 60-80 in/lbs.
5. Check adjustments made by using the Air Dump switch to deflate air
springs. Start the engine and allow the air system to become fully
charged. Allow the suspension to reach a neutral setting.
6. Re-check the suspension height measurement. Follow the same procedure
for each rear control valve.
7. Re-check the front suspension height after adjusting the rear height
control valves.
NOTE: Do not modify length
of the linkage rods. Make any
necessary adjustments using
eccentric slot on the ride height
control valve.
