35. Remove the detent assembly and turn the shift drum until 2nd gear
is fully engaged. Then, while holding the shift drum to the right, screw
the detent assembly inward two or three turns. If the shift drum rotates
slightly, check the gear engagement to insure that it is the same as when
you previously checked it. Again, if the amount of engagement is
insufficient, replace the shift drum.
36. While still in 2nd gear, and with the detent assembly still in place, install the selector shaft mechanism, pushing it in firmly until it is fully seated, and the return spring is on the anchor pin. Take note that there are two shift drum selector pins between the tips of the selector pawl. Each of these two pins should be an equal distance away from the tips of the pawl (Fig. 60). If they are not, the end of the selector return spring will need to be slightly bent until these pins are centered between the pawl tips. If you must bend the spring, be sure that after it is bent, the ends are still a snug fit on the anchor pin.
37. Remove the selector and cletent assemblies, and repeat both these checking processes for 3rd and 4th gear. If the location of the selector pins varies from one gear to another, or if insufficient engagement of the gears occurs after installing the cletent, the shift drum will necessitate replacement.
