24. INSTALL REAR DISC

(a) Aligning the matchmarks, install the rear disc.

HINT: When replacing the rear disc with a new one, select the installation position where the rear disc has the minimum runout.

25. INSPECT DISC RUNOUT

(a) Temporarily fasten the rear disc with hub nuts.

Torque: 103 NVm (1,050 kgfVcm, 76 ftVlbf) (b) Using a dial indicator, measure the disc runout 10 mm (0.39 in.) away from the outer edge of the rear disc.

Maximum disc runout: 0.15 mm (0.0059 in.) (c) If the runout exceeds the maximum value, change the installation positions of the disc and axle so that the runout will become minimal. If the runout exceeds the maximum even when the installation positions are changed, check the bearing play in the axial direction and the axle hub runout (see page 30-3 ). If the bearing play and the axle hub runout are normal and if the disc thickness is not within the specified range, shave the disc. If the disc thickness is less than the minimum, replace the disc.
