Check of radial and lateral run-out drive
| Fig. 12.1. Measurement surface runout: H - radial runout; S - lateral runout |
Secure the drive with no tires on the axle of the balancing device. Establish a measuring tip of the dial indicator on the radial first and then on the side of the inner surface of the disk on which the tire bead rests (Fig. 12.1). Slowly turn the hands of the balancing disc device at the same time removing the indicator. It does not consider the deviation indicator arrows on local protrusions or indentations on the disc. If the runout exceeds the maximum permissible limits, replace the drive.
NOTE Maximum heartbeat steel disc: n = 0,8 mm, S = 1,0 mm. Maximum runout alloy wheels: H = 1.5 mm, S = 1,5 mm. |
