5. Bend away the tab of the lock washer (12) on
the drive shaft, loosen the lock nut and remove
the gear. Insert a NEW gear spacer (6mm) on
the drive shaft. Place the gear, lock nut and lock
washer consequently and tighten referring the
‘Gearbox Assembly’ (chapter 6.7) Finally, adjust
the rotor timing to be correct.
6.
If the rotor timing is correct, measure the position of
the gear on the drive shaft relative to the gear on the
idle shaft using a depth micrometer shown in Figure
28. Adjust the gap using a spacer and shim(s)
according to the below cases.
* If the gear on the idle shaft is more forward than
the gear on the drive shaft, as shown in Figure 29,
add a 6 mm spacer and shim(s) on the idle shaft to
fill the gap.
* If the gear on the driving shaft is more forward than
the gear on the idle shaft, as shown in Figure 29,
add a 5 mm spacer and shim(s) on the driving shaft
to fill the gap.
7. Reattach the gears to the shafts with the locknut and bend one lip of the locking lip into a
groove of the locknut.
