Figure 25 5. Assembly of gearshift fork assembly Assembly of gearshift fork assembly is comparatively simple, which can be assembled with reference to the disassembly drawing. 6. Regulation and assembly of input shaft assembly Place the input shaft with its end with clutch spline down, and then set the third gear needle bearing applied with the gear oil of the same designation as that used inside the transmission assembly onto the input shaft. Set the third gear driving gear assembly in from upside of input shaft with the end with synchronizer cone of the gear assembly up, and then check and make sure that the gear assembly can rotate freely. Set a 3/4/5 gears synchronizer ring in from upside of input shaft with conical surface of the synchronizer ring applied with the gear oil of the same designation as that used inside the transmission assembly, and then check and make sure that the synchronizer ring should envelop loosely on synchronizer cone of the third gear driving gear assembly and can rotate relative to the synchronizer cone. Press 3/4 gears synchronizer assembly onto the input shaft with the end surface of gear hub with two oil grooves down, turn the synchronizer ring to make its guide block completely enter the groove corresponding to the gear hub, and then make sure that the synchronizer ring is not locked. Fit front snap ring of input shaft; when fitting, try to use the thicker snap ring, if really unsuitable, select the snap ring of next thinner level, and then check if the snap ring has really enter the groove with the clearance between the snap ring and the groove not exceeding 0.05mm. Set a 3/4 gears needle bearing applied with the gear oil of the same designation as that used inside the transmission assembly onto the input shaft from upside of the input shaft. Set a 3/4/5 gears synchronizer ring applied with the gear oil of the same designation as that used inside the transmission assembly in from upside of the input shaft. Set the fourth gear driving gear assembly in from upside of input shaft with the end with synchronizer cone of the gear assembly down (the guide block of 3/4 gears synchronizer ring should completely enter the groove corresponding to the gear hub), and then make sure that the gear assembly can Selector lever bracket bolt (with tightening torque as 25±2Nm) Reverse gear locking mechanism bolt (with torque as 18±2Nm) |
