Abstract
The application discloses a method of assembling gears, transmission shafts, fork shift shaft and associated component parts of a 5-speed transmission for a vehicle. The fifth-speed gear and the hub therefor are designed to be installed outside the end of the transmission case which is remote from the end thereof secured to a clutch housing. After first to fourth-speed gears and associated component parts are mounted on the transmission shafts which have already been mounted at their one ends to bearings mounted on the clutch housing, the transmission case is moved over the transmission shafts, the gears and the associated component parts thereof in such a manner that an open end of the transmission case is directed toward the clutch housing until the open end of the transmission case reaches the clutch housing and the other ends of the transmission shafts are inserted into and project through bearings mounted on the other end of the transmission case. After the transmission case is secured at its open end to the clutch housing, the fifth-speed gear and the associated hub are mounted on the projecting ends of the shafts. The fifth-speed gear and the projecting end portion of the associated transmission shaft are provided with internal and external splines for engagement with each other. A cylindrical first jig is threadably connected to the end extremity of the projecting end portion of the shaft. Thereafter, the fifth-speed gear is axially movably mounted on the first jig. An annular second jig is then positioned around the first jig and axially outwardly of the fifth-speed gear and forcibly urged by a mechanical or hydraulic device against the fifth-speed gear to press-fit the same onto the splined part of the projecting end portion of the output shaft while the first jig is caused to take up the reaction force generated during the press-fitting of the fifth-speed gear.
