Measure wheel rim width at front and rear and
make a note of the figures.

Place track alignment gauge,
BMW No. 36 3 920, against the left or right side
of the motorcycle.

Note:
In order to use the track alignment gauge on either
the left or right side, simply screw the supports in on
the other side.
•
Adjust supports (1) so that the measuring plane
is as close as possible to the wheel centreline.
The gauge must slide freely up to the motorcy-
cle.
•
Adjust measuring stops (arrows) until they con-
tact the rim - not the tyre.
•
Connect hook (2) to a wheel spoke and use it to
pull the gauge firmly up to the wheel.
•
Align front wheel parallel with the gauge.
•
Release tension in the track alignment gauge by
raising it by approx. 5 mm (0.1969 in) at the front
and lowering it again.
