(d) Conduct the equilibrium test on the dynamic balancer,
the amplitude value displayed should not be larger than
13.5g under the condition that the measuring rotating
velocity is 796 r/m and the locking rotating velocity is
786 r/m, when the amplitude value is larger than 13.5 g,
encase the counter balanced clip, which is 4 g each, at the
corresponding phase, the number of the clip encased
should not be more than four.
7. Bearing outer race change
Press in the new bearing outer space with the special service
tools.

one time.
Assembly of Front Wheel Hub
1. Mount on the Bearing 32007 inner race and roller assem-
bly as well as the front wheel hub oil seal.
Coat the lithium base grease of (4-5)mm on the inner surfaces
of bearing outer race and the front wheel hub, encase the
Bearing 32007 inner race and roller assembly, plaster the
lubricant again. Coat a little lubricant on the lips of front wheel
hub oil seal and then tap it in place.
Notice: do not make the lubricant contact the front brake
disc face.
2. Mount on the Bearing 32007 inner race.
After coating the bearing outer race with the lithium base
grease of 4-5 mm, encase the inner race and roller assembly of

(d) Hook the front wheel hub with the spring-tension meter
and pull the spring-tension meter slowly in the tangential
direction of this spot.

Remark: if the tension force is larger or smaller of the reason-
able range, screw up the nuts again until the tension force falls
within the reasonable range.
(e) Measure the bouncing value of the front brake disc,
which should not be larger than 0.11mm.

it with the bracket.
(b) Tread down the brake pedal after verifying that the front
wheel are in straight line.
(c) Move the arm vertically to check the lower ball stud to see
whether the clearance is overlarge.
Max vertical clearance : 0.5mm
2. Check the upper ball stud to see whether it is over-loose.
Move the wheel vertically to check whether the clearance of
the ball stud is over large.
3. Check the rotating performance of ball stud
