2. Pull boot/bellows completely over the collar of the shock absorber, so that it engages (small diameter downward, 2nd worker required).
3. Fit rubber stop (small diameter downward).
4. Position the air spring on the shock absorber. Grasp the rolling piston and push it downward by turning it slightly to the left and right. If the rolling
piston has slipped out of the outer guide, it must be pushed back in again while forming a circumferential uniform roll fold on the rolling boot
-Arrows-.

5. Clean the surfaces -2- on the mounting saddle and on the air spring with a lint-free cloth. Replace sealing ring -1- on the air spring.

Information
To align the air spring, carefully turn the rolling piston in order to not damage the roller.
6. Fit and align the air spring. While doing so, the residual pressure retaining valve -1- must be located exactly at the imaginary axis of symmetry
-Arrow- of the air-spring strut. The residual pressure retaining valve must be facing in the opposite direction to the CDC valve.
