1. The transmission is housed in an aluminum alloy cast crankcase bolted to the rear of the engine. The drive to the input shaft of the transmission is transmitted from the crankshaft through the clutch friction disc. From the input shaft of the transmission, the drive is transmitted to an intermediate shaft located under the input shaft; both shafts are parallel to the crankshaft and propeller shaft.
2. Gear shifting is carried out by means of a lever installed in the floor of the passenger compartment, connected by a rod to the gear selection mechanism. The movable transmission link causes the corresponding shift fork to move the synchronizer sleeve along the shaft, as a result of which the ring gear of the desired gear meshes with the synchronizer sleeve hub.
Since the synchronizer hubs are splined to the output shaft, the drive is transferred to the shaft. Synchronizers for fast and smooth gear changes are installed in all forward gears. They consist of locking rings, a hub fitted with spring-loaded crackers and a coupling.
