GATE
An exact H-shifting pattern is used through the gear change shaft guide in the gate.
A finger attached to the gear change shaft ensures alignment of the corresponding guide groove in the gate, depending
upon the selected shift gate. In the engaged gear, the gate limits the side-to-side freeplay at the shift lever.
SYNCHRONISATION
The purpose of a synchromesh is to allow the collar and the gear to make frictional contact before the dogteeth make
contact. This lets the collar and the gear synchronize their speeds before the teeth need to engage. The cone/s on the
gear fits into the cone-shaped area in the collar, and friction between the cone and the collar synchronize the collar and
the gear. The outer portion of the collar then slides so that the dogteeth can engage the gear.
Fast and easy shift engagement of the transmission is achieved by single, double and triple cone synchroniser
mechanisms.
