Balancing Weights; Affixing The Adhesive Weights - Porsche 996 TT Repair Manual

The imbalance values shown here in this speed range are not real values. They are actually max. 1/4 to 1/3 of
the indicated values.
The subjective impression in the vehicle is the decisive criterion here. The balancing process is complete only
when no more vibrations caused by imbalance are perceptible!

Balancing weights

Balancing weights: Adhesive weights as used previously (no special version necessary). Also refer to the
spare parts catalogue.
Affix both weights on the inner side.
Note
• Observe program selection and operating instructions of the balancing machine.

Affixing the adhesive weights

Note
• Remove the protective film only immediately prior to sticking on the weight, as prolonged exposure
to the air will reduce the bonding strength!
• Pay attention to cleanliness!
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.
The adhesive weight 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.
