In case the outer tilt angle of front wheel or the back tilt angle
of kingpin fails to conform to the specified value, adjust the
cam forward or backward may amend them.
5. Wheel angel adjustment
Take apart the limit bolt cap of the steering knuckle to check
the inner wheel steering angle A.
The inner wheel steering angle: =32
Notice:The wheel should not touch the body brake hose
when the steering wheel is rotated to the bottom.
In case the max steering angle is not in the conformity with the
standard value, adjust the wheel angle through the limit bolts
of steering knuckle.
In case the wheel angle still fails to fall within the standard
range, make a inspection and change the weary and damaged
steering mechanism parts.
6. Wheel toe-in adjustment
Adjust the wheel toe-in according to the following approach
(a) Raise or reduce the vehicle until the suspension stands in
balance.
(b) Push the vehicle on the ground 5 meters forward under
the condition that the front wheels locate forward in a
line.front cam adjustment

6. Inspection and replacement for front brake disc
(a) Check the wear situation of the front brake disc. (see Dr
the brake caliper).
(b) Use the spanner to 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
bolt and spring washer, and screw up the bolts with a
moment spanner to the specified torque in the diagonal
order.
Fastening torque(60-79)Nm
(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.
Notice: the bearing inner and outer races should be changed at
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
Bearing 30205, and plaster the lubricant again.

Steering Knuckle
Disassembly of Steering Knuckle
1. Take apart the brake caliper, the front wheel hub and the
front brake disc.
2. Take apart the front brake shell:
(a) Tear down the two bolts (M8X16).
(b) Tear down the two split pins, grooved nuts, washer and
bolts that connect the steering knuckle arm.
3. Tear down the steering knuckle
(a) Support the lower arm with jack;
(b) Tear down the two split pins and the grooved nuts
(c) Disconnect the steering knuckle from the upper and
lower ball studs and take apart it.
Inspection on Steering Knuckle
Check the steering knuckle
Check the steering knuckle with the dye penetration agent to
see whether the steering knuckle has a crack or not.
If the crack is found, the steering knuckle is required to be
changed.
