Gear Control Lever





Gearshift control lever (1) pattern.

Gear Shift Lever Operation





Gear selection is transmitted from the gearshift control lever (8) into the gearshift lever case (6) located at the rear of the transmission. The gearshift lever case (6) contains a gearshift arm (9), a reverse gearshift limit yoke (5), and a gearshift lever (4). These three components are attached to the gearshift shaft (7). The gearshift control lever (8) is fitted into the gearshift arm (9). When the gearshift control lever (8) is moved, the gearshift arm (9), the gearshift shaft (7) and the gearshift lever (4) are moved forward, backward, left or right, depending upon the gear selected.




Gear Shift Lever Components

Reverse Gearshift Limit Yoke





The reverse gearshift limit yoke (5) is located in the gearshift lever case and rides on the gearshift shaft. The reverse gearshift limit yoke prevents the transmission from being shifted directly from fifth gear (1) to reverse. When the transmission shifts into 5th gear, the gearshift limit spring (4) turns the gearshift limit yoke clockwise causing the reverse gearshift limit yoke to land on the reverse gearshift limit bolt (3). This action prevents a 5th-to-reverse gearshift.





Shifting from 5th gear (2) to neutral (1) is possible with the reverse gear shift still canceled. This is due to the reverse gearshift limit yoke (5) making contact with the reverse gearshift limit bolt (3) preventing further gearshift control lever (6) rearward movement.





When the gearshift shaft is turned to the neutral position between 3rd and 4th gears (1), the gearshift limit spring turns the reverse gearshift limit yoke (6) counter-clockwise away from the reverse gearshift limit bolt (2). This action cancels the limiting mechanism and allows a reverse gearshift.
After the reverse gearshift limiting mechanism has been canceled, reverse gear is then available.
