Installation

Installing

Note

When topping up or filling in Pentosin, make sure that it does not come into contact with the coolant hoses.
Observe the specifications in order to avoid overfilling, and thus overflowing.

If coolant hoses come into contact with Pentosin, clean them thoroughly with water IMMEDIATELY.

• 

Replace visibly swollen coolant hoses.

• 

Tighten all threaded connections to the specified tightening torque.

• 

Install in reverse order. It is essential to observe the following points while doing so:

–  Replace steering-gear fastening screws, the fit bolt of the steering shaft and the steering-wheel

fastening screw whenever they have been removed. Screw threads must be clean and free of
grease.

–  Ensure that no damage (scoring) is caused to the steering rack.

Tie rod on steering gear

–  Mount the tie rods on the steering gear. Then secure the respective bellows with new clamping rings → Tie

rod on steering gear .

–  Position red plastic clip on steering-gear pinion. The plastic clip ensures that the fastening screw between

the universal joint and steering pinion sits into the groove on the steering pinion.

–  Push on universal joint (steering shaft) with the steering gear and steering wheel or airbag contact unit

(spring) in centre position. For ease of assembly, just insert steering-gear fastening screws.

–  Observe following notes for sliding piece and airbag contact unit!

Sliding piece

1. If sliding piece -1- was pulled off the steering shaft -4- , the notch -2- must point towards the tooth

gap -3- during assembly.

2. If the steering wheel was not fixed before the steering gear was removed, the position of the contact unit

(spring) may no longer be correct. In this case, remove steering wheel and move contact unit to centre
position because otherwise the spring will be damaged.

Contact unit in centre position

Contact unit

–  To position the airbag contact unit in centre position, press the latch -D- and turn the rotor -A-

carefully to the left as far as it will go.

–  Then (from the furthest left position) turn the rotor -A- carefully to the right, approx. 3.5 to 3.75

turns, until the band printed on one side is visible in the window.

3. Turn front wheels to straight-ahead position before fitting the steering wheel (steering shaft mounted on

steering gear).

WARNUNG

Gefahr des Verlusts der Text-Bild-Zuordnung beim Ausdruck.

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.
