911 Turbo AWD F6-3600cc 3.6L SOHC Twin Turbo (1997)
-
This will ensure that optimum balancing results (achieved using finish balancers) will not be affected by tire fitting.
Notes About Adhesive Wheel Weights
General
-
Balancing weights are affixed on the inside on Technology wheels (Turbo wheels) Turbo Look wheels, Targa wheels and Sport Classic wheels.
-
On all other 911 Carrera wheels, the balancing weights are affixed conventionally (inside and outside).
-
It is also possible to affix the balancing weights on the inside.
In this case, the balancing weights must be affixed very carefully to ensure permanent attachment.
Affixing The Adhesive Weights Conventionally
-
Determine exact position of the balancing weights (if necessary, provisionally stick on the balancing weights with a strip of adhesive tape until the
correct position is determined).
-
Prepare bonding surface on the rim.
The bonding surface must be perfectly clean and free of grease.
-
Remove protective paper from the bonding surface of the weight and press the weight firmly into place.
NOTE: Remove the protective film only immediately prior to sticking on the weight, as prolonged exposure to the air will reduce the bonding
strength and, furthermore, there is a risk of soiling.
-
The adhesive weight must be affixed exactly on the level ring surface of the wheel.
It must be in contact uniformly over the entire surface.
-
Check to ensure that the balancing weight is seated firmly.
It must not be possible to detach the weight that was just stuck onto the rim by the application of a shear load at right angles to the longitudinal
axis of the weight.
Affixing The Adhesive Weights On The Inside
Example: Technology wheel/Turbo Look wheel

Balancing weights
Type of balancing weights:
Adhesive weights as with conventional attachment (special version not necessary). See Spare Parts catalogue.
-
Arrangement: Affix both weights on the inner side (arrows).(*)
Here, the outer weight must not be fastened in the conical area.
A cylindrical area intended especially for fastening of the weights is therefore provided just behind the rim spider.
Footnote
(*) Observe program selection and operating instructions of the balancing machine.
Optimizing Tire and Wheel to Vehicle
Preliminary
The entire process is subdivided into four operations.
1. Mounting the tire on the rim.
2. Stationary balancing of the wheel (eliminating the static and dynamic imbalance) with optimization of the rolling smoothness.
3. Mounting the wheel on the vehicle.
4. Electronic fine balancing (static balancing) of the wheel on the vehicle (after stationary balancing if necessary/not required in most cases).
Step 1: (Mounting The Tire On The Rim)
-
Remove rubber residues and dried-on tire paste from the rim, especially from the rim bead and the hump.
