Colour marking of spring/damper

The marking, item number and colour dot coding -C- are shown on the damper tube.

Assembling spring strut

ATTENTION

Increased risk of accidents due to spring tensioning.

Danger of injury and damage from springs jumping out.

• 

→ Never use an impact bolter to loosen or tighten the fastening nut.

→ Use a commercially available changeover ratchet.

Note

Observe the correct allocation (vehicle version and equipment) when installing new coil springs
and/or shock absorbers.

• 

Observe allocation of compensating plate according to the coil spring tolerance range.

• 

Coil springs are only available in pairs.

• 

1. 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. Slide the bellows/additional spring assembly onto the piston rod.

Cone washer

3. Mount cone washer -8- and stop plate -7- in correct position.

4. Push the pretensioned coil spring onto the vibration damper so that the end of the coil spring rests

against the stop of the spring plate.

Supporting mount assembly

5. Completely assemble the spring plate (compensating plate) -6- , support ring -5- and bearing with its

housing -4- with the spring strut supporting mount -3- . Then slide the assembly onto the piston rod.

6. Place spring strut supporting mount assembly onto the piston rod so that the end of the coil spring is

located inside the spring plate.

Supporting mount (correct seat)

7. Fit stop plate in the correct position (domed side upwards) and screw a new fastening nut onto the piston

rod. Important: For PASM spring struts, place the lug of the stop plate (in area of spring strut mount) in
the groove of the piston rod (twist lock of piston rod opposite the supporting mount). Make sure that the
plastic part of the bearing sits correctly in the recess of the supporting mount -arrows- .

Stop plate position (PASM only)

8. On PASM spring struts, before tightening the lock nut, align the stop plate -2- offset 45° from

direction of travel marking -Arrows A- of the supporting mount.

The value: 45° + - 2° is necessary so that the two grooves of the stop plate (cut-outs for countering) are
positioned over or between the recesses (pockets in the rubber part) which lie below.

Spring strut mount

9. Tighten fastening nut to the specified tightening torque. For PASM spring struts, counter at the stop

plate using retaining tool P 9630/1. For conventional spring struts, counter at the hexagon socket
of the piston rod using special tool P 9630.

10. If present, push on clip (vibration balancer) at damper tube of vibration damper. Final assembly

(tightening) only on completion of wheel carrier.

Aus technischen Gründen kann derzeit nicht ausgeschlossen werden, dass trotz
einwandfreier Darstellung auf dem Bildschirm beim Ausdruck der
Zusammenhang von Text und zugehörigem Bild verloren geht.

• 

Wird der Fehler nicht bemerkt, besteht die Gefahr, daß Arbeiten nicht korrekt
durchgeführt werden und es dadurch zu Personen- und Sachschäden kommt.

• 

→ Vergleichen Sie deshalb nach dem Druckvorgang unbedingt die Ausdrucke mit der
Bildschirmdarstellung. Korrigieren Sie die Ausdrucke im Fehlerfall so, daß der Inhalt der
Bildschirmdarstellung zutreffend wiedergegeben wird.

WARNING

Danger of losing text-figure correspondence when printing out.

For technical reasons, it can currently not be ruled out that the correspondence
between text and associated figure can be lost when it is printed out, even though
the display on the screen is correct.

• 

If the fault is not noticed, there is the danger that work will not be performed
correctly which can cause injury and damage.

• 

→ Therefore, always compare printouts with the screen display after printing them out. Correct
the printouts if they are faulty so that the content of the screen display matches that on the
printouts.

AVERTISSEMENT

Risque de perte de la correspondance texte-illustration lors de l'impression papier.

Pour des raisons techniques, il ne peut pas être exclu à l'heure actuelle que, même
en cas d'affichage correct à l'écran, la correspondance entre le texte et l'illustration
puisse être erronée sur l'impression papier.

• 

Si l'erreur passe inaperçue, on court le risque d'exécuter certaines opérations de
manière incorrecte pouvant conduire à des dommages corporels et matériels.

• 

→ Comparez impérativement pour cette raison les impressions papier avec l'affichage à l'écran.
Corrigez-les en cas d'erreur de manière à reproduire correctement l'affichage à l'écran.

ATTENZIONE

Pericolo di perdita dell'abbinamento testo-immagine nella stampa.

Per motivi tecnici non è escluso che, nonostante la rappresentazione sullo schermo
risulti perfetta, durante la stampa venga persa la corrispondenza fra testo e
relativa immagine.

• 

Se tale difetto non viene rilevato vi è il pericolo che i lavori non siano eseguiti
correttamente; ciò può avere come conseguenza lesioni e danneggiamenti.

• 

→ Per questo motivo, dopo la stampa è assolutamente necessario confrontare le stampe con la
rappresentazione sullo schermo. In caso di errore si prega di correggere le stampe, così da
garantire la riproduzione esatta della rappresentazione sullo schermo.
