Disassembling Spring Strut

→ Do not reach into the danger area.

→ Relieve the tension on components before starting work.

→ Secure components to prevent them from loosening suddenly.

1. To prevent damage (deformation), clamp the spring strut in a suitable clamping block (tensioning device for MacPherson spring struts). Alternatively, the spring clamp can also be held in a retaining device.
2. Tension the coil spring using a spring clamp for spring struts Nr.121  until the piston rod is relieved. The appropriate forks must be inserted into the spring clamp.

3. Remove spring strut mount. To do this, loosen the lock nut on the piston rod (with coil spring pretensioned).

   Use a socket-wrench insert 9630/2  to loosen the lock nut on conventional spring strut mounts. On PASM spring struts, use a suitable socket-wrench insert, e.g. socket-wrench insert for ATF temp. switch assembly Nr.18  .

   When loosening the nut, counter at the piston rod (hexagon socket) or at the two grooves (cut-outs) on the stop plate (for PASM spring struts). Tools required: retaining tool 9630/1  and for conventional spring struts: counter-hold tool 9630  .
