- Split gearbox housing and clutch housing as described in Section. 8.2.1. Fig. 179 shows the parts located in the gearbox. Some items may already be removed, if the gearbox has been completely dismantled. Shaft 6 (fig. 179) of the gearshift must clear the mandrel after the tube 5 is removed (see. Fig. 167). The mandrel is installed as shown in Fig. 168. If necessary to remove the gearshift finger 1 (see. Fig. 179), after the installation or replacement should hold its adjustment, as described in the previous section to establish alignment with the coupling sleeve.
