9. 5th Gear. To shift the transmission from 4th gear to 5th gear, the
gearshift is again lifted upward. The rotation of the selector shaft causes
the selector pawl to move upward, rotating the shifting drum clockwise.
The sliding dog, K, moves to the right, disengaging gear D. It continues
to move toward the right until it engages gear E. The transmission is now
in 5th gear, as shown in Fig. 37. The power flows directly along the mainshaft,
as the sliding dog is locked to the shaft, and gear E is engaged into the
sliding dog, making the mainshaft one unit. The layshaft is completely
bypassed, and all other gears turn freely. Because there is no gear reduction
in 5th gear, the ratio is 1:1 in all OSSA transmissions.
10. Neutral. The neutral position is located halfway between 1st and
2nd gear. To shift into neutral from 1st gear, the [ever is lifted gently
until a slight click is felt. This is neutral. From 2nd gear, the lever
is pushed gently downward until engagement of neutral is felt. In either
case, the shift lever is not moved all the way to its limit, as this would
cause engagement of the next gear. When shifting from 1st to 2nd, or 2nd
to 1st, the neutral position is disregarded, moving the lever right through
to the desired gear. In the neutral position, all sliding gears and dogs
are in a neutral ' or disengaged position. There is no power flow from
the mainshaft to the layshaft.
