What should we do if the air spring is over-extension
Over-extension is an unlimited lowering of the axle, that forces the air spring to consistently operate beyond its maximum extended height. This may happen during traction of a crane or shipping of a vehicle without limiting cables on the axles. The first sign of damage on an over-extended air spring is usually the bellow separating from the metal top plate or at the piston.
Air spring failures resulting from over-extension are most commonly seen on lift axle applications and particularly on trucks or tractors used in severe on/off road service such as construction, logging or quarrying. On those types of vehicles, check to see if the shock absorbers are missing, need to be repaired or replaced. Although shock absorbers were not designed as axle travel limiting devices, they are often the only defense against over-extension.
Maintenance instructions:
Bring the air spring back into the proper operating zone by:
– Limit the axle movement,
– Check height control valve to see that it is functioning
properly.
– Adjust the height control valve to proper ride height.
– Check the correct using of the bellows.
