5. Tear down the front hub, the oil seal and the inner race
of front hub bearing (inner)
(a) Prize out the oil seal.
(b) Take out the inner race of front hub bearing (inner).
6. Inspection on and change of the outer race of front hub
bearing
(a) Check each bearing:
Wash the inner and outer races of each bearing to check
their wear or damage situation.
(b) Tear down the outer race of each bearing:
Tap out the outer bearing race with copper bar and hammer.
Notice: bind the inner and outer races of the same
bearing together to prevent from mixing.
7. Inspection and change for front brake disc
(a) Check the wear situation of the front brake disc.
(b) Tear down the bolts that connect the front wheel hub and
the front brake disc.
(c) Connect the front wheel hub and the front brake disc with
bolts, which are tightened diagonally with moment span-
ner according to the specified torque.

(d) Make the dynamic balance test on the dynamic balancer,
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.
(e) Tap in the new bearing outer race carefully with the
special service tool.
Notice: the inner and outer races of the same bearing
should be changed in one time.

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
Coat 4
5 mm of lithium base grease on the outer race of
bearing, and then put the inner race of front hub bearing (outer)
and roller assembly in it, finally plaster with lubricant.
(c) Loosen the steering knuckle nut to ensure the front brake
disc can run freely. Screw up the steering knuckle nut
again to the specified torque.

Coat a little lubricant on the oil seal of steering knuckle, and
then mount the front wheel hub and front brake disc on the
steering knuckle, finally mount on the stop washer.
4. Adjust preload:
(a) Mount on the steering knuckle nut and screw it up
according to the specified torque.

(b) Run the front wheel hub by 1/4-1/3 round so as to seat the
bearings.

(e) Hold the bolt of front wheel hub with the spring-tension meter
and drag slowly in the direction of the spot tangent line.
Suitable tension range
(29-54)N
The nut should be screwed up again within the suitable range if the
tension value is overlarge or over small.
(f) Check the bearing to ensure it cannot leap excessively (the
axial clearance should not be more than 0.05mm).
(g) Measure the bouncing value of the front brake disc, which
should not be more than 0.11mm, and
5. Mount the liner and the free hub:
(a) Tear down the free wheel hub cap firstly.
(b) Mount the liner and the free hub on the front wheel hub.
