Figure 50: Drawing the axle height on the front and
back of both tyres of the running wheels
Afterwards measure the distance between the
running wheels front and back at the height of
the axles along the markers. Ideally, the dis-
tance between both running wheels should be
the same size at the front and back. In general,
it can be said that the distance between the
running wheels at the front and back may not
be larger 5 mm. If this is not the case, the
wheel tracking needs to be corrected.

tyres (at axle height), back
To
adjust the track
proceed as follows:
1. Loosen the aluminium locking nuts on both
sides (AF 41 mm).

ing nut (rear view)
2. Correctly adjust the track by turning the
drive wheel bushing (AF 24 mm). Here it
can be said that: If you turn the drive wheel
bushings in the direction of travel, the track
at the front will become narrower. The ex-
act opposite occurs if you turn it opposite
to the direction of travel; the track becomes
wider.
3. Make sure that the distance at the front to
the frame on the right and left is the same.
