8. Each specification shall be followed strictly. And the torque
spanners should be used.
9. Determine the necessity of using the special service tools (SST)
or special service materials (SSM) according to the real situation.
SST and SSM must be used where necessary and the repairing
should be in accordance with the repairing approach. SST list
and SSM list are attached to this manual.
10. Be sure to check whether the rated current of the new fuse is

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.

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.

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.
