1. Install the magnet and the differential assembly.
2. Install the primary shaft gear assembly and the
secondary shaft gear assembly together.
3. Shift to 2nd gear and position the shift fork and shift
rod assembly as shown.
Insert the spring seat and spring into the reverse
lever shaft, install the steel ball, and place a scraper
knife so that it contacts the steel ball.
With the edge of the control end against the knife,
when the control end is pushed in the direction of
the arrow in the figure so that the ball goes into
the shaft, the rod will at the same time line up with
the shift rod coupling hole in the clutch housing.
6. Set each clutch hub sleeve to the neutral position,
and tap the shift rod from above so that the steel
ball goes into the center groove (of the 3 grooves
in the control end).
7. Pull the ball part of the control end forward so that
the steel ball goes into the detent in the groove.
