Toe-in
Turn the clamping bolt clockwise. The track rod gets longer and the wheel is
pressed to the back and outwards.
Setting a toe-in causes the inner side of the tyre to wear faster.

Toe-out
Turn the clamping bolt anticlockwise. The track rod gets shorter and the
wheel is pressed to the rear and to the inside.
Setting a toe-out causes the outer side of the tyre to wear faster.

e) Mounting the center differential (optional)
When converting, the main pinion can be replaced by a main pinion with integrated differential.
This center differential prevents the tensions occurring in the drive section of all-wheel driven vehicles, which result from the different turning radius of front
and rear axles and the associated different rotational speed of the axles.
Remove, for a better accessibility, the empty tank by unscrewing both crosshead screws on the lower side of the chassis.
Remove the RC mounting plate.
To that effect, you must remove numerous screws. Notice their position and mounting orientation.
Unscrew:
two screws respectively on the casings of the differentials at the front and the back (supports of
the transverse stabilisators)
the servo steering lever from the throttle/brake servo
one screw on the servo saver (counter hold the screw on the lower side of the chassis!) and one
screw on the articulated joint of the middle steering link
the screw at the spacer bolt chassis/RC mounting plate
wo screws at the brake supports and the cardan shaft-bearing case
Removing the disk brake and the support
Remove two crosshead screws of the brake support on the bottom side of the supporting plate.
Remove the spacer bolts between the brake supports and the cardan shaft bearing case (on the
side of the brake support).
Loosen the disk brake fastener (one screw).
Remove the headless screw on the attachment of the front cardan shaft and remove the attach-
ment.
Remove the brake support.
Now you can remove the main pinion from the cardan shaft-bearing case and replace it with a main pinion with differential.
f) Conversion to automatic two-speed transmission (optional)
Function and setting of two-speed transmission
There are two pinions tightly screwed on the clutch bell with a different number of teeth. The two main cogwheels on the centrifugal clutch are connected with
each other via a one-way bearing. The shift point depends on the revs.
In the first running step, the engine speed is transmitted from the small pinion on the clutch bell onto the bigger toothed wheel on the drive section, the toothed
wheel for the second running step runs idle.
At high speeds the centrifugal force causes the lever of the centrifugal clutch to be pulled outward towards a spring resistance and the attachment on the
toothed wheel grips into the second running step.
The engine speed is now transmitted via the larger pinion of the clutch bell to the smaller toothed wheel in the drive section, the toothed wheel in the first
running step is running via the one-way bearing.
The shift point of the two-speed transmission can be adjusted.
