TOTAL PRELOAD

Drain the oil.

Remove electric controlled coupling assembly. Refer to

RFD-19, "Removal of Electric Controlled Coupling

Assembly"

Rotate the drive pinion back and forth in 2 to 3 times to check for unusual noise and rotation malfunction.

Rotate the drive pinion at least 20 times to check for smooth
operation of the bearing.

Fit the drive pinion socket onto the drive pinion spline. Using a
preload gauge, measure the total preload.

●

If outside the standard, disassemble, check, and adjust each
part. Adjust the pinion bearing and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.

DRIVE GEAR RUNOUT

Drain the oil.

Remove the rear cover.Refer to

RFD-19, "Removal of Differential Assembly"

Attach dummy cover set. Refer to

RFD-15, "DRIVE GEAR TO

DRIVE PINION BACKLASH"

Fit a dial gauge to the drive gear back face.

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

Fit a dial gauge onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).

Rotate the companion flange to check for runout.

Fit a test indicator to the inner side of the companion flange
(socket diameter).

Rotate the companion flange to check for runout.

If the runout value is outside the repair limit, follow the procedure
below to adjust.

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.

If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.

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

Drain the oil.

Remove the rear cover. Refer to

RFD-19, "Removal of Differential Assembly"

Attach dummy cover set. Refer to

RFD-15, "DRIVE GEAR TO

DRIVE PINION BACKLASH"

Thoroughly clean drive gear and drive pinion teeth.

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.
