SAME SILVER 100.6 - 4 WD Front Axle, Specifications; Adjusting Wheel Alignment and Steering Angle

FRONT-WHEEL DRIVE
The front-wheel drive is designed so that the front axle centre coincides with the transmission shaft centre of rotation.
The latter, directly linked without universal joints, transmits the movement to the front wheels through a centre differential unit and
two final epicyclic reducers installed in the wheel hubs.
Specifications
Adjusting toe-in
Adjust the front wheel tie rod so as difference A-B shown in figure 1 be:
wheel rim keying diameter A-B mm
2-W.D. 4-W.D.
up to 20" (508 mm) 2 to 6 0±2
20" to 30" (509 to 762 mm) 3 to 6 0±3
over 30" 3 to 6 0±3,5
Adjusting steering angles
Make sure the front drive wheel steering angle is as specified in
table above.
Otherwise adjust by way of the special setscrews or spacers.
