Gear Shift Construction
The
gear
shift
operation
is
made very
light
by
mounting the
gear shift
drum
on
ball
bearings, fur-
ther,
the
use of the special neutral stopper permits
easy
and positive shifting
into neutral.
Stopping on the gear shift pedal
causes the
gear
shift spindle to rota
te
and
moves
the
gear shift
for
k.
The
pin on the end of the
shift
fork
turns
the gear
shift
drum and
it in
turn moves the gear
shift
fork
which is mounted on the
drum.
The shift
drum
stopper positively
sets
the gears in
their respective
position
