46 51 040 Measuring wheel track off-
set
– Wheel bearings, zero play.
– Rims checked for runout.
•
Place the motorcycle on its main (centre) stand
on a flat, level surface.
•
Place the track offset gauge,
BMW No. 36 3 920, against the left or right side
of the motorcycle.
L 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 track alignment
gauge, BMW No. 36 3 920, is installed as high
as possible and align it horizontally.
•
Position the measuring stops (arrows) so that
they touch the wheel rim and not the tyre.
•
Attach hook (2) to wheel spoke to secure the
gauge firmly to the wheel.
•
Align front wheel parallel with the gauge.
•
Measure gap with depth gauge (3) from outer
edge of gauge up to rim and note reading in
measurement record.
•
Measure rim widths front and rear with caliper
gauge and note reading in measurement record.
•
Calculate wheel track offset “S”.
Wheel track offset “S” is the distance to left or right
of the longitudinal axis of the rear wheel from that of
the front wheel.
Track offset (S):
...........................+ 3.5 mm (+ 0.1378 in) (= to right)
Permissible wheel track offset (S):
.............................................. ± 9 mm (± 0.3543 in)
based on + 3.5 mm (+ 0.1378 in)
L Note:
Key to measurement result:
Negative sign = wheel track offset to left
Positive sign = wheel track offset to right
