4.1.16. Check of a radial and side beating of a disk with the tire by means of the indicator of hour type for tires V.A.G 1435

Check of a side beating
Previously pull the indicator of hour type for tires approximately on 2 mm.

Fig. 4.15. Check of a side beating


Put the indicator to a sidewall of the tire (fig. 4.15).
Slowly scroll a wheel.
Write down the minimum and maximum deviation of an arrow.

NOTE
If the difference is more than 1,3 mm, then the side beating is considered exceeded.

In this case it is possible to reduce it by means of minimization.
Indicator arrow deviations because of small roughnesses on rubber should not be considered.

Check of a radial beating

Fig. 4.16. Check of a radial beating


Previously pull the indicator of hour type for tires approximately on 2 mm (fig. 4.16).
Put the indicator to a tire protector.
Slowly scroll a wheel.
Write down the minimum and maximum deviation of an arrow.

NOTE
If the difference is more than 1 mm, then the radial beating is considered exceeded.

In this case it is possible to reduce it by means of minimization

Check of a radial and side beating of a wheel
Install a wheel on the balancing stand.
Use the collet self-unclenched adapter for balancing VAS 5271 stands.
Previously pull the indicator of hour type for tires approximately on 2 mm.

Fig. 4.17. Scheme of check of a radial and side beating



Slowly scroll a wheel. Write down the minimum and maximum deviation of an arrow.
S – Side beating.
H – Radial beating.
Compare the received value to nominal parameters in table 4.4.

NOTE
Indicator arrow deviations because of small roughnesses on rubber should not be considered.

NOTE
If the measured value exceeds nominal, then normal smoothness of the course will not manage to be reached.
