Porshe 911 (997). Manual - part 258

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.

ADVERTENCIA

Al imprimir se corre el riesgo de perder la correcta asignación de las figuras al texto.

Por motivos técnicos, por el momento no se puede descartar que, aun siendo
correcta la imagen que aparezca en la pantalla, al imprimir se pierda la
correlación entre el texto y la figura correspondiente.

• 

Si este error pasara desapercibido, existe el riesgo de que los trabajos no se
ejecuten de forma correcta y, por tanto, se produzcan daños personales y
materiales.

• 

→ Por ello le rogamos que tras el proceso de impresión compare siempre las copias impresas con
la imagen de la pantalla. En caso de error, corrija las copias impresas de forma que se
correspondan con el contenido de la imagen de la pantalla.

Removing spring strut

ATTENTION

Danger of crushing (damaging) electric lines (cables) at point of exit from piston rod on PASM spring
struts.

PASM (damping force adjustment) does not function.

• 

→ Protect electric lines (cables) when removing and installing the spring strut.

→ Do not damage electric lines (cables) during transport, unpacking, storage or when disassembling

or assembling spring strut.

1. Vehicles with PASM: With ignition switched off, carefully disconnect electric line from the PASM

spring strut at the connector and unclip it from the bracket.

Lock nuts on spring-strut mount

2. Loosen M10 lock nuts on the spring-strut mount -arrows- (in the vehicle interior).

Anti-roll bar/spring strut/toe control arm

3. Remove anti-roll bar together with the

suspension/stabilisers.

To do this, remove the right -1- and left suspension/stabiliser at the wheel carriers and loosen the anti-roll
bar at the rear-axle side sections (four M8 screws).

When loosening the suspension/stabiliser (1), counter with a Torx
screwdriver.

4. Loosen toe control arm -2- at the wheel carrier.

5. Remove spring strut/wheel carrier threaded connection -3- and pull spring strut up (over the upper trailing

1191

Danger of crushing (damaging) electric lines (cables) at point of exit from piston rod on PASM spring
struts.

PASM (damping force adjustment) does not function.

• 

→ Protect electric lines (cables) when removing and installing the spring strut.

→ Do not damage electric lines (cables) during transport, unpacking, storage or when disassembling

or assembling spring strut.

Installation is in reverse order. Before installing, check the various parts carefully. Replace lock nuts.
Do not grease threaded connections in Dacromet finish - aluminium colour. Observe correct tightening

1. Insert spring strut into the vehicle from above (over the upper trailing arms).

Lock nuts on spring-strut mount

2. Fit M10 lock nuts (three nuts) -arrows- onto the spring strut mount (in the vehicle interior). Tightening

torque: 46 Nm (34 ftlb.).

3. Vehicles with PASM: Connect electric line for the PASM spring strut (connector must engage) and

clip it into the bracket.

Anti-roll bar/spring strut/toe control arm

4. Fit spring strut to wheel carrier. Tightening torque of fastening screw -3- = 110 Nm (81 ftlb.).

5. Fit toe control arm to wheel carrier -2- . Tightening torque of lock nut = 75 Nm (56

ftlb.).

6. Install anti-roll bar together with the

suspension/stabilisers.

Tightening torque: Anti-roll bar to rear-axle side section (four M8 screws) = 23 Nm (17 ftlb.).

Suspension/stabiliser to wheel carriers -1- = 65 Nm (48 ftlb.). Please note: Tighten in three
steps (step 1: tighten to 50 Nm (37 ftlb.) / step 2: loosen by 90° / step 3: tighten to 65 Nm (48
