Note
To clamp the wheel, use e.g. centring system for wheel bal‐
♦
ancing machines -VAS 5271- .
This ensures that the wheel is 100% centred and that the
♦
wheel will be clamped without damage!
The wheel cannot be centralised 100% with conical clamping
♦
elements on the wheel balancing machine.
A deviation of 0.1 mm from the centre results in an imbalance
♦
of 10 grams at the wheel/rim.
Procedure for balancing wheels and tyres
– Rotate wheel and tyre on wheel balancer.
– Check that the indicator lines on the sidewall of the tyre near
the wheel rim flange run evenly.
– Check that the body of the tyre runs evenly while the wheel
and tyre are rotating.
Note
If one-sided wear, flat spots from braking or severely washed out
spots are apparent, balancing cannot achieve smooth running. In
this case, the tyre must be renewed.
– Check the true running of the wheel and tyre. If the wheel and
tyre do not run true although there are no flat spots, radial or
lateral runout may be the cause.
– Check the wheel for radial or lateral runout
– If radial and lateral runout are within the specified tolerance,
balance the wheel and tyre.
Note
More than 60 grams of weight per tyre should not be used.
♦
If more weight is required, you may be able to achieve smooth‐
♦
er running by "matching" the tyre and rim. Matching tyres
⇒ page 330 .
The wheel balancer display should indicate 0 gram.
♦
As an alternative to match mounting, you could use the vibra‐
♦
tion control system -VAS 6230-
– Bolt the wheel to the vehicle.
– First hand-tighten the lowest wheel bolt to about 30 Nm.
– Then tighten the remaining wheel bolts diagonally to about
30 Nm. This process centres the wheel on the hub.
– Lower vehicle onto its wheels.
– Now use a torque wrench to tighten the wheel bolts to the
specified torque in diagonal sequence.
Carry out road test
– After balancing the wheels and tyres, carry out a road test.
