General Information

5th and Reverse Speed

The 5th and reverse speed gears synchronizer unit is assembled on the countershaft, unlike
the other speed synchronizers that are assembled on the mainshaft. By its turn, their
corresponding gears on mainshaft are assembled fixed to the mainshaft.

1. With the 5th speed gear shifted, torque is transferred from countershaft to the mainshaft

corresponding gear through the clutching teeth of the synchronizer hub.

2. When the reverse speed gear is shifted, torque is transferred from countershaft to the reverse

idler gear, that changes the rotating direction, and then, from that to the mainshaft reverse
speed gear.
