In 5th Gear Position
•
When the shift lever is shifted into fifth gear, the main shift fork shaft moves rightward (see figure), which
simultaneously moves the fifth shift head and the fifth shift head stopper block rightward. As the fifth shift head
stopper block is fixed to shift fork shaft No.2 by a pin, the shift fork shaft moves when the shift head stopper
block moves. Likewise, the reverse shift arm head, which is fixed to shift fork shaft No.2 by a pin, also moves
rightward. As a result, the fifth/reverse shift fork moves leftward through the shift arm connected to the reverse
shift arm head, thereby shifting the gear into fifth gear. At the same time, the interlock block in section A fixes
the shift forks in neutral position except for the fifth shift and reverse shift arm heads. Also, shift fork shaft No.2,
which is moved rightward by the fifth shift head, presses onto the ball which is out of the ridge to fix shift fork
shaft No.3, thereby preventing double engagement during fifth gear shifting.
