Structure

Layout

•  The shift locking bush prevents two gears from being engaged at the same time.

The selector interlock maintains engagement of the selected gear.

Both the shift and the select process is performed through the selector shaft.

Select movement

•  The axial movement of the selector cable is transferred at the transmission to the selector shaft which can turn in its bearing.

If the gearshift lever is moved to the left or right, the selector shaft and the selector boss both turn together in the corresponding direction.

As this happens, the selector shaft is guided by a pin in the selector gate.

The selector boss selects the required selector fork.

At the same time the shift locking bush prevents access to other gear combinations.

Shift movement

•  After the gear pair to be shifted has been selected, the shift movement takes place.

Here the axial movement of the shift cable at the transmission produces an axial movement of the selector shaft.

If the gearshift lever is moved forwards or backwards, the selector shaft and the selector boss both move vertically together.

As this happens, the selector shaft is guided by a pin in the selector gate.

The selector boss shifts the required selector fork.

At the same time the shift locking bush prevents access to other gear combinations.

Engage reverse gear

•  In order to select reverse gear, the gearshift lever must be moved to the right over and past the reverse gear inhibit device. As this occurs the axial movement of the selector cable is transferred to the selector shaft which can turn in its bearing.

When shifting into reverse gear, the gearshift lever is moved backwards. The selector boss engages in the 5th gear/reverse gear shift rod, which in turn engages through a pin in the reverse gear selector shaft.

During the select and shift process the selector shaft is guided through the selector gate by a pin.

The reverse gear idler is slid by the reverse gear selector shaft and reverse gear is engaged.

At the same time the shift locking bush prevents access to other gear combinations.
