will damage the cases.
c. Carefully rotate the shift drum while
turning the output shaft. Check that all
gears engage smoothly and that each gear
position can be identified. You will have
to spin the output shaft quickly to keep
the "neutral finder" from locking you out
of 2nd and higher gears. Refer to Chapter
Six if the transmission does not work
d. Remove the lower case half.
13. Make sure the crankcase mating surfaces
are completely clean and dry.

20. Rotate the crankshaft to make sure the
bearings are not too tight.
21. Carefully rotate the shift drum while
turning the output shaft. Check that all gears
engage smoothly and that each gear position
can be identified. You will have to spin the
output shaft quickly to keep the "neutral
finder" from locking you out of 2nd and higher
gears. Refer to Chapter Six if the transmission
does not work correctly.
22. Insert the secondary shaft through the
clutch side of the engine, through the thrust
washer (Figure 147) and into the starter clutch
assembly, aligning the shaft splines with the
secondary sprocket splines.
23. Before the secondary shaft is all the way in,
check that the 2 oil pump dowels are in place
(Figure 148) and hold the bearing retainer in
place (Figure 149).
24. Tap the secondary shaft into place with a
large socket placed over the secondary drive
gear until the clutch side bearing bottoms in the
