Note: Remember to allow for thick-
ness of bar.
Now measure selector shaft bet-
ween the two stop faces (fig. 49).
This value will always be smaller
than the sum of the two obtained
to fig. 47 and 48.
Fit washers on the shaft between
ball bearing and speedometer drive
until only a play of 0.1 mm remains
(for swinging fork machines).
Example:
Measurement obtained
to fig. 47 22,7 mm
Measurement obtained
to fig. 48 + 349mm
Sum 57,6 mm
Dimensions, fig. 37 = 56,9 mm
0,7 mm
Axial play — OI mm
Packing washers required 0,6 mm
For
engines
of
machines
with
telescopic
fork,
a
spacer
bush
is
fitted
to
the
collar
of
the
selector
shaft,
since
the
speedome-
ter
drive
is
taken
from
the
front
hub.
Measuring Selector Gears
Fit the selector shaft with the num-
ber
of
packing
washers
calculated
into
the
left
casing,
then
fit
selector
gears in sequence in such a way
that
the
larger
collar
faces
down,
i.e.
towards
the
larger
gear.
Gears
are
correctly
fitted
if
only
onb
oil
groove
lies
between
each
two
gears,
and
the
arrow
at
the
side
points to the next larger gear.
Next,
with
the
depth
gauge,
mea-
sure
distance
from
end
face
of
selector shaft to stop face of selec-
tor gear (fig. 50).
