Notes on self-locking nuts and bolts

AH00.00-N-0001-01A

The air spring (41) may only be removed together with the container for additional volume (41p). The connector hose from the air spring (41) to the container for additional volume (41p) must not be detached as leaks occur as a result. Furthermore it is to be ensured that the air springs (41) are emptied completely before removal with STAR DIAGNOSIS. If the air springs (41) are not installed and filled according to the specifications, these can be predamaged and malfunction a short time later.

 Installation: Tighten nuts and bolts of chassis components only when vehicle is in the ready-to-drive condition.

Disconnect pressure line (41a) from air spring (41)

 Installation: When reinstalling the old air spring (41) ensure that the pressure line (41a) is screwed carefully onto the plastic thread, as if screwed on improperly the plastic thread will be damaged and therefore the air spring (41) will be irreparably damaged.

 Installation: If a new air spring (41) is installed, detach the old screw connection on the pressure line (41a). To do this break open the clamping ring, detach bolt head and insert pressure line (41a) up to marking in the new screw connection. Pull back pressure line (41a) a short distance so that the peripheral retaining edges in the inside of the clamping ring engage in the line outer surface.

 Seal pressure line (41a) with blind plugs during repair work.

 Installation: Damaged pressure line connections or damage pressure lines (41a) must be repaired before assembly.
