Minor Repairs
259
If a
wheel needs to be changed
, the procedure
described below must be
adhered to exactly
, as
otherwise the wheel may loosen, resulting in
damage. Porsche cannot be held liable if this
happens.
To achieve the high tightening torque required for
the central bolt, a suitable, commercially available
443 ftlb. (600 Nm)
torque wrench
must be used.
Alternatively, a corresponding tool with torque
multiplier (part no. 997.450.323.90) is available
from Porsche Motorsport. When a torque
multiplier is used, the torque must be reduced in
accordance with the tool’s operating instructions.
When loosening and fastening the wheel, a
second person is needed
to prevent the wheel
from turning by firmly braking it.
The high mounting forces involved can cause the
vehicle to roll away and slip off the jack.
f
Always use a lifting platform if there is one
available.
Risk of damage due to vehicle tipping over or
falling off lifting equipment or using the wrong
tool.
The high mounting forces involved can cause the
vehicle to roll away and slip off the jack. An impact
wrench can damage the central lock.
f
Always use a lifting platform if there is one
available.
f
Do not use an impact wrench
.
1.
Apply the electric parking brake, move the
PDK selector lever to position
P
and remove
the key from the ignition.
2.
Secure the vehicle
carefully in both
directions
to prevent it from rolling away, e.g.
using wedges at the wheels on the opposite
side.
This is particularly important on slopes.
3. Raise
the vehicle
until the wheel lifts off the
ground. Lift the vehicle only at the specified
jacking points.
f
Please see the chapter “RAISING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 254.
Information
The vehicle must not be standing on the wheel to
be secured during fitting.
4.
Open the luggage compartment and lift the
plastic cover
A
.
Please see the chapter “TIRE FILLING
COMPRESSOR” on page 198.
Open the receptacle
B
and remove the
polygon tool.
The central bolt must only be opened using
this original polygon tool. Always leave the
polygon tool in the luggage compartment to
ensure that it is always available in the event of
a breakdown.
Risk of damage from scratching.
f
Proceed with care when removing the wheel-
hub cap.
