1. The following items should be checked to remove the
troubles.
(a) Check the tire abrasion and the air inflation to see it is
suitable or not.
Tire inflation pressure: (2500)kPa
(b) Check the front wheel bearing to see whether it is loose.
(c) Check the front suspension to see whether it is loose.
(d) Check the steering driving device to see whether it is
loose, and
(e) Check the front vibration through elastic force test to see
whether it is normal in performance.
2. Height adjustment of vehicle
Adjust the vehicle height to the standard value so as to make
the Alignment of Front Wheel inspection.
A-B-58 5mm
A: The height of steering knuckle shaft center.
B: The center height of the adjusting cam bolt at front end
The standard value for the unloaded height is: the
difference of the center height of drive shaft climax and
the front adjusting cam bolt is 58.5mm.
3. Mount on the four wheel locating device
This approach should be conducted according to the detailed
instruction of the equipment manufacturer.
4. Adjust the outer tilt angle of front wheel and the back tilt
angle of kingpin
The outer tilt angle of front wheel: 05'0'
The back tilt angle of kingpin: 20'0'
