| Description |
Because of the design layout, the air spring and the shock
absorber (damper) is separated. The average (target) pressure of rear
air spring for normal operation is around 8.5 bar.
When the rear air spring is delivered as service spare part,
no air is filled so that the intensive care is required to handle. It
will be explained more detail in the section of ‘Caution of
handling’.
Due to the stopper inside of spring, the upper end and lower
end do not contact (gap exists around 10mm) each other even if the air
is totally discharged.
Take care to handle the rear air spring. Don’t pull the air
spring intentionally, it may very difficult to restore to the original
shape. If it was extended untended, a small amount of air pressure
inside spring will help you pushing the spring to the original position.
