Construction and Function of Gear Shifting Mechanisms.

Gear Shifting Mechanisms

3. Operation of double-meshing prevention mechanism
The shift fork lock plate fits into two of the three shift fork head slots at all times and locks all shift forks except for the gear to be used.
For example, when the shift lever is put into 1st or 2nd gear, the shift fork lock plate and shift inner lever No. 1 move to the right as shown in the diagram on the left.
The shift fork lock plate prevents the 3rd/4th and 5th/reverse shift fork heads from moving so that only the 1st/2nd shift fork head can move.
