When assembling the synchronizer of the first and second gears, make sure that the shoulder on the synchronizer sleeve and the narrow part of the synchronizer hub are directed towards the first gear (indicated by arrows in Fig. 200). Install the 3rd and 4th gear synchronizer sleeve onto the hub so that the groove on the sleeve and the wide part of the hub are on the same side (arrow in fig. 200). The female side of one locking ring is adjacent to seven drivers. Push the drivers one by one onto the locking rings and slide the synchronizer hub into the synchronizer sleeve.
