6. Tighten the adjusting nut of the hub bearings with the aid
of a wrench applying a hand effort to the wrench tommy bar 300-
350 mm long until the wheel is rotated with difficulty (Fig. 61).
When tightening the nut, apply the effort to the tommy bar
smoothly without jerks and simultaneously rotate the wheel to
allow the roller to assume correct position on races of the
bearings.
7. Back off the nut 1/4 to 1/3 of a turn (1.5-2 flats) and
install the locking washer, screw in and tighten the lock nut.
Replace the washer if some cracks on the tabs of the locking
washer are detected.
8. Check adjustment of the bearings after tightening the
locking nut. If the adjustment is correct, the wheel should rotate
freely, without binding noticeable axial play and wobbling.
9. Bend the one tab of the locking washer round the flat of
the nut, bend the second tab round the flat of the locking nut.
(Fig. 62).
10. Reinstall the axle shaft of the rear axle (driving flange)
and front axle wheel disengaging coupling, install the spring
washers and tighten the bolts.
After a run, check the wheel hub for correct bearing
adjustment by its heating. If the hub overheats, back off the nut
1/6 of a turn (1 flat), observing the above sequence and rules.
When checking the bearing adjustment by hub heating, do
not apply the service brakes since the hubs will be heated from
the brake drums.
