Using a wrench, carefully tighten the hub mounting nut until the axial clearance in the bearings is 0.04-0.06 mm.
Attach the bracket with the indicator to the hub body.
Check the axial clearance in the rear wheel hub bearings by carefully tightening or loosening the hub mounting nut. If the mounting nut is tightened too much, the axial clearance adjustment is disrupted and the spacer sleeve must be replaced. When loosening the hub mounting nut, you do not need to make adjustments to the axial clearance of the hub bearings.
Lock the hub fastening nut in two places by pressing the holes on the nut neck into the grooves on the rear wheel hub (Fig. 233).
