3D-14 Propeller Shafts:
Tooth Contact
CAUTION
!
Make sure to check the backlash after the
tooth contact has been adjusted, since it may
have changed. Adjust the tooth contact and
backlash until they are both within
specification. If the correct tooth contact
cannot be maintained when adjusting the
backlash, replace the rear output shaft drive
and driven bevel gears.
1) Remove the special tool and rear output shaft (1)
from the left crankcase.
2) Clean and degrease several teeth of the drive and
driven bevel gears, and then apply a coating of
machinist's layout dye or paste to several teeth of
the rear output shaft driven bevel gear.
3) Install the rear output shaft.
4) Rotate the rear output shaft driven bevel gear
several turns in both directions.
5) Remove the output shaft and inspect the coated
teeth of the rear output shaft drive bevel gear. The
tooth contact pattern should be as shown in [A], [B]
and [C].
If tooth contact is found to be incorrect (examples [A]
and [C]), the shim thickness between the rear output
shaft drive bevel gear and bearing must be changed
and the tooth contact re-checked until correct
(examples [B]).
