Volkswagen Touran Service Manual: Wheel, Balancing with Fine Balancing Machine (Finish Balancer)
Before beginning balancing, the following requirements must
be fulfilled. |
The tire pressure must be OK. |
The tire profile must not be worn on one side. The tire
profile must be at least 4 mm. |
The tires must not have any damage such as cuts, holes,
foreign bodies, etc. |
The suspension and steering, including the shock absorber,
must be in perfect condition. |
Test drive performed. Refer to
→ Chapter "Vibration, Road Test, Performing Before Balancing". |
Note
If equipped handle the glued-on wheel trim carefully.
Surface slightly scratched. |
Replace the damaged rim wheel trim. |
Use only the Model-Specific Clamping Plate -VAS6652- and the
Thrust Pin -VAS6652/1-. |
Note
Working with a Finish Balancer requires instruction from the
manufacturer of the balancer. |
When balancing, place the wheels of the driven axle on the
turntable sensors. On a FWD vehicle, the front wheels must be on
the sensors. On AWD vehicles, all 4 wheels must be on the
sensors. |
If it is determined when balancing on the vehicle the
remaining imbalance is more than 20 grams, the wheel should be
rotated on the wheel hub. |
|
Mark the point at which the imbalance is indicated. |
|
Afterwards, unbolt the wheel and rotate its position on the
wheel hub so that the marking points downward. |
Note
The wheel hub must not turn during this procedure. |
|
First, tighten the lowest wheel bolt hand-tight to
approximately 30 Nm. |
|
Tighten the remaining wheel bolts diagonally to
approximately 30 Nm. This process centers the wheel properly on
the wheel hub. |
|
- Check again whether the imbalance is less than 20 grams
using the finish balancer. |
Note
The imbalance should not be smaller than 20 grams under any
circumstances before changing balance weight. |
|
Loosen the wheel bolts again, if necessary. |
|
Rotate the wheel relative to the wheel hub once more by one
or two wheel bolt holes. |
|
Tighten the wheels according to the method described above. |
Note
Only if the imbalance is less than 20 grams should the
imbalance be reduced by changing the balance weight. |
|
Balance the wheels until the imbalance is below 5 grams. |
|
Tighten the wheel bolts to the specified tightening
specification if you have not already done so. |
Always Tighten the Wheel Bolt to the Tightening
Specification and Using the Torque Wrench. |
