Transmission System Description and Operation

This 5-speed transmission assembly adopts the synchronised mesh type of 5 forward speeds. The reverse speed gear is driven by sliding idle gear without synchroniser.

5th and reverse gear cam prevents the gear from directly being shifted from 5th to reverse when shifting to reverse from 5th. So, when shifting to reverse, be sure to shift to reverse from neutral position.

In case of shifting to 5th gear, shift and select shaft rotates to right that shift and select lever arm fixes on the groove of 5th and reverse gear shift cam.

When shifting to reverse from 5th gear, shifting to reverse is impossible because 5th and reverse gear shift cam fixes on cam stopper case.

When shifting to reverse from neutral position between 5th and reverse, gear shift and select lever arm rotates to left and shifting is possible.

The differential is integrated with transmission case and installed on chassis together with engine. It changes the direction of power and increase torque by reducing speed.
