Checking running gear

Measuring track offset

•

Mount motorcycle on centre stand on even base.

•

Position track offset gauge (1),
BMW No. 36 3 920, on left or right side of motor-
cycle.

Note:

In order to measure with the track offset gauge from
the left or right side, the supports need only be
screwed in from the other side.

•

Adjust supports (2) so that the measuring level is
as near as possible to the centre of the wheel. It
must be possible to smoothly slide the gauge to-
wards the motorcycle.

•

Adjust limit stops (arrows) so that they only rest
on the rim and not on the tyre.

•

Attach hook (3) to wheel spoke and firmly pull
gauge up to the wheel.

•

Align front wheel parallel with respect to the
gauge.

•

Measure distance with depth gauge or straight
edge from outer edge of gauge to rim and note
down measurement.

•

Calculate track offset ”S”:

EXAMPLE:

•

The track offset ”S” represents the amount by
which the longitudinal axis of the front wheel is
offset to the left or right with respect to the rear
wheel.

Permissible track offset:
S .................................................................. 12 mm

Note:

Significance of measurement result:
Negative sign = Track offset to left
Positive sign = Track offset to right

Formula:

S =

–

Fixed value „A“
(length of measuring stops)

A = 50,0 mm

half of rear wheel rim width

= 44,5 mm

Measured value „B“

B = 52,0 mm

half of front wheel rim width

= 41,0 mm

Track offset „S“

S =

–

S = 94,5 mm – 93,0 mm

Track offset „S“ = 1,5 mm

the left and right with respect to the measuring
discs.

Note:

The frame is in order when the tips of the measuring
pins on the left and right are located in approximate-
ly the same position within the grid circle.

Max. deviation:

Left to right

................... 2 mm (0.0787 in) = 2

boxes
