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.

(d) Mount on the lock plate and another steering knuckle nut.
Tighten torque60Nm
(e) Hold the front wheel hub bolts with a spring-tension
meter and drag the meter slowly in the direction of the
tangent line of this spot.
Suitable tension range: (29-54)N
The nuts should be retightened until falls within the suitable
range if the tension force is overlarge or over small.
(f) Check the bearing and ensure that the clearance, which is
not larger than 0.05 mm, is not excessive.
(g) Measure the bouncing value of the front brake disc face.
Bouncing value should not be above o.11mm.

Assembly of Front Wheel Hub
1. Mount on the inner race and roller assembly of front hub
bearing as well as the oil seal of front hub.
Coat the lithium base grease of (4-5)mm on the inside surfaces
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
