①
Install a shim (33) of about 1 mm (0.04 in.) on axle shaft
and install cover (29). The shim provides a clearance
between end face of axle shaft and inner surface of cover
(29).
Tighten four bolts (25) with washers to a torque of 108 N·m
(80 lbf·ft).
Give housing (12) two to three turns and tighten bolts to a
torque of 108 N·m (80 lbf·ft) again.
Repeat this work several times until tightening torque of
bolts no longer fluctuates.
(NOTICE)
Tighten four of the eight bolts (25) alternately in the
diagonal directions.
(NOTICE)
Push in the inner race while rotating the bearing.
Otherwise, even strongly trying to push the inner
race, the bearing rollers will not be pushed up and
therefore bearing will not be seated.
