1. The design of the rod-cable shift actuator RKPP 716.644 is shown in the illustrations, the last of which includes all references in the text.
2. Lever assembly is no longer bolted to the cabin floor, but is attached to the transmission.
3. This design features improved switching accuracy and ease, as well as no need for a tunnel for moving components.
4. The articulated arm assembly, combined with the equipped rubber pads of the mounts, provides freedom of movement of the transmission joint with the engine.
5. Rotation of the central rod (16) around its axis is provided by transverse displacements of the shift lever due to the organization of a cable drive.
6. Axial displacement of the central rod (16) carried out by moving the lever in the longitudinal direction using the switching rod (13).
7. To release the reverse gear lock, the shift lever handle should be pulled up.
