4th Speed
The 4th speed gear is also named direct speed gear.
1. Torque from the engine is transferred to the
transmission’s input shaft that, despite driving
the countershaft at the same time, transfers the
torque directly to the mainshaft. The input shaft
clutching teeth engage the clutching teeth of the
4th speed synchronizer unit which transfers the
torque to the mainshaft.
The transmission’s noise level in this speed is much
reduced, since torque is delivered directly from one
shaft to another and there are no gears under load.
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 xed to the mainshaft.
1. With the 5th speed gear engaged, 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 engaged, torque
is transferred from countershaft to the reverse
idler gear, which changes the rotating direction,
and then, from that gear to the mainshaft’s
reverse speed gear.
