and the amplitude value displayed should not be smaller
than 13.5g under the condition that the measuring rotat-
ing velocity is 796 r/m and the locking rotating velocity
of 786 r/m, otherwise, tap the counter balanced clip,
which is 4g each, in the corresponding position, the clip
number should not be more than 4.

of the bearing outer race and the front wheel hub, put in the
inner race and roller assembly of front hub bearing (inner),
then plaster the lubricant. Plaster a little lubricant on the lips of
front wheel hub oil seal, and finally tap the front hub in place
with special service tool.
Notice: Do not plaster the lubricant on the face of front
brake disc.
2. Mount the inner race of front hub bearing (outer) and
roller assembly
