Alignment of Front Wheel
Alignment of Front Wheel (SF)
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
