Checking the radial and lateral runout of the disc (Opel Astra J)

Fix the disk without the tire on the axis of the balancing device. Install the measuring tip of the dial indicator first on the radial and then on the lateral inner surface of the disk, on which the tire bead rests (Fig. 1).

Note: Maximum runout of steel disk: H = 0.8 mm; S = 1.0 mm.

Maximum runout of light alloy wheel: H = S = 1.5 mm.

Slowly rotate the balancing device disk with your hands, while reading the indicator. Do not take into account any deviations of the indicator arrow from local protrusions or depressions on the disk.

If the maximum runout is greater than the specified value, replace the disc.
