Remove the rear cover.Refer to
RFD-19, "Removal of Differential Assembly"
.
3.
Attach dummy cover set. Refer to
4.
Fit a dial gauge to the drive gear back face.
5.
Rotate the drive gear to measure runout.
●
If outside the repair limit, check drive gear assembly condi-
tion; foreign material may be caught between drive gear and
differential case, or differential case or drive gear may be
deformed, etc.
CAUTION:
Replace the drive gear and drive pinion gear as a set.
COMPANION FLANGE RUNOUT
1.
Fit a dial gauge onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2.
Rotate the companion flange to check for runout.
3.
Fit a test indicator to the inner side of the companion flange
(socket diameter).
4.
Rotate the companion flange to check for runout.
5.
If the runout value is outside the repair limit, follow the procedure
below to adjust.
a.
Check for runout while changing the phase between companion flange and drive pinion gear by 90
°
step,
and search for the point where the runout is the minimum.
b.
If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c.
If the runout value is still outside of the limit after the companion flange has been replaced, possible cause
will be an assembly malfunction of the drive pinion gear and the electronically controlled coupling, mal-
functioning coupling bearing, or malfunctioning electronically controlled coupling.
TOOTH CONTACT
1.
Drain the oil.
2.
Remove the rear cover. Refer to
RFD-19, "Removal of Differential Assembly"
3.
Attach dummy cover set. Refer to
4.
Thoroughly clean drive gear and drive pinion teeth.
5.
Lightly apply a mixture of powdered ferric oxide and oil or the
equivalent. Apply it to 3 to 4 teeth of drive gear drive side.
