Volkswagen Touareg / Touareg repair>> Running gear>> Wheels and tires>> Balancing
Before starting balancing should be satisfied the following conditions.
Pressure of air in the tire should be in norm.
Drawing of a protector should not have unilateral wear, and its depth should make not less than 4 mm.
The tire should not have no damages, like cuts, the punctures, extraneous subjects, etc.
The wheel suspension bracket, steering, steering drafts, including shock-absorbers, should be in a faultless condition.

Trial trip before balancing
If on the authorized station the car with the complaint to «not smoothness of a course» arrives, before balancing surely follows execute a trial trip.
Thus the master should familiarize with nature of malfunction.
In movement follows establish, on what speed there is an imbalance.
At once after a trial trip lift the car on the lift.
Mark on each tire a place of its installation.
To dismantle wheels and отбалансируйте wheels.

Balancing at the stationary balancing stand
Clamp a wheel at the balancing stand.

NOTE
It is necessary to remember. when balancing wheels, as well as at any other repair, the most important rule is purity. Only watching purity, it is possible to achieve faultless result.
Dirt and rust in the field of a prileganiye and a centering opening of a wheel distort result.

Before establish a wheel on the balancing stand, clear a prileganiye surface, a centering opening and a disk.
Establish a wheel with the tire on the balancing stand.

Fig. 4.13 . Tsangovy adapter



NOTE
For an inhaling of a wheel use, for example, the tsangovy being self-unclenched adapter for balancing VAS 5271 stands (fig. 4.13) .

At its use 100 percent centering of a wheel and a careful clip of a disk is guaranteed.
Conic adapters for centering do not provide 100 percent centering of a wheel at the stand.
At a deviation from the center on 0,1 mm on a wheel and the tire there is an imbalance in 10 grams.

Order of works when balancing wheel/tyre
Scroll a wheel with the tire at the balancing stand.
Check a course of marking strips on боковинах tires in the field of onboard закраины.
Check protector drawing at a rotating wheel.

NOTE
At unilateral wear, wear spots because of braking with the blocked wheels or strong non-uniform wear balancing to reach smoothness of a course it will not be possible. In this case it is necessary to replace the tire.

Check accuracy of rotation of a wheel with the tire. If the wheel with the tire rotates roughly though flattening of the tire is not present, radial and lateral palpation can be the reason of it.
Check a disk with the tire on existence of radial and lateral palpation.
If radial and lateral palpation are in admission limits, отбалансируйте a wheel with the tire.

NOTE
Do not use more than 60 grams of weight on a wheel.
If it is necessary more грузиков, if necessary it is possible to reach good balancing at the expense of minimization.

Minimization
On the display of the balancing stand 0 grams should be displayed.
Alternatively it is possible for minimization use the balancing VAS 6230 stand.
Fasten a wheel to a nave.
At first tighten the lowermost wheel bolt with the moment about 30 N · m.
Then tighten other bolts also on 30 N · m cross-wise. At the expense of it the wheel is centered on a nave.
Lower the car on wheels.
Now tighten wheel bolts cross-wise by means of a dinamometrichesky key for the ordered moment of an inhaling.
After balancing of wheels execute a trial trip.
If at a trial trip palpation nevertheless is felt, the balancing error because of wheel centering can be its reason.
Errors of centering of wheels and naves in adverse cases can be imposed at each other. For this reason palpation is also possible. It is possible to eliminate it by means of the stand for finishing balancing.

Balancing control VAS 6230 stand

Fig. 4.14 . Balancing stand


By means of the balancing control VAS 6230 stand, besides known static balancing, it is possible to carry out additional functions (fig. 4.14) .
Feature of this system is check of radial effort of a wheel with the tire during rotation.
During this check on a wheel presses a roller with effort about 635 kg. Thus, the force operating on a basic surface of a wheel from a surface of the road to time of movement is simulated.
Because of radial and lateral palpation in a wheel and the tire and various rigidity in the force tire. operating on the square of contact of the tire with the road change.
The VAS 6230 system distinguishes and remembers the provision of the maximum measured radial effort in the tire. By means of it the provision of the smallest distance between onboard zakrainy rims and the disk center is measured.
