4. Adjust the wheel angle
Take apart the limit bolts of the steering knuckle to check the
steering angle A of inner wheel.

Remark: The wheel should not contact the body or brake hose
when the steering wheel reaches the limit position.
In case the steering angle of inner wheel doesnít conform to the
standard value, adjust the wheel angle through adjusting the
limit bolts of the steering knuckle.

If the wheel angle fails to be adjusted within the standard value,
change the weary or damaged parts of steering system.
If the tilt angle fails to fall within the specified values, make an
adjustment through adding or reducing the gaskets on the
location of upper arm.
Gasket thickness: 3.0, 2.0 and 1.0mm
Once the gasket thickness increases by 1mm, the outer tilt
angle of wheel will change by 7', while the back tilt angle of
kingpin will change 20'.
After the wheel outer tilt angle and the back tilt angle of kingpin
are adjusted, if the inner tilt angle of kingpin still fails to the
specified value, check the steering knuckle or front wheel to
see whether they are bending or loose.

6. Wheel toe-in adjustment
(a) Verify that each wheel has been located forward in a line.
(b) Mark the tire center at the bearing height on the tread of
left and right tire, and measure the distance between the
marks on left and right treads.
(c) Push forward the vehicle until the mark on the back tread
of tire moves to the front.
Remark: the toe-in measurement should be conducted from the
same spot at the same height.
(d) Measure the distance between the two marks on the front
of two treads.
Toe-in value: (0-2)mm
(e) Loosen the clamping bolts of connecting pipe.
(f) Adjust the toe-in angle through the approach according to
which rotate the left and right drag rod tube by a same
angle.
Remark: check the lengths of the two drag rods to see whether
the two rods are same in length.
Length error of the left and right drag rod should not
be larger than 2.0mm.
(g) Tighten the clamping bolts.

(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.

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.
