To adjust the suspension ride height begin with:
• The motorhome on flat level surface.
• Air system fully charged.
• Ignition key on.
• Suspension at normal ride height.
Start by checking the distance in the front.
1. Measure the distance between the mounting plates 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
all 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 adjust and come to 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.
