THREE SPEED TRANSMISSION
There are also three gears on the output shaft. These
three gears rotate freely on the gear sleeve. The gear
sleeve is coupled to the output shaft with a roll pin so
the gear sleeve always rotates with the output shaft. The
gear selection system determines which one of these
three gears will be coupled with the gear sleeve and the
output shaft. This determines the final drive ratio.
The shift keys are retained on one end by the shift
collar. Movement of the shift fork positions the shift collar
and shift key. The shift fork is supported, both top and
bottom, by nylon bushings for smooth operation and long
wear (Fig. 117).

Gear Selection System:
Gear selection is determined by moving sliding shift
keys in a sleeve that is fixed to the output shaft. These
keys engage one of the three gears that rotate on the
gear sleeve. Once the key engages one of the gears,
that gear will rotate the output shaft. Table 1 shows
approximate speeds in gears for two different engine
speeds.
