14) Set dial gauge to bevel pinion mounting dummy and
make 0 (zero) adjustment on surface plate.
NOTE
• When setting dial gauge to mounting
dummy, tighten screw lightly. Be careful
not to overtighten it, which will cause
damage to dial gauge.
• With dial gauge set, turn dummy back and
forth by hand a couple of times and attain
accurate 0 (zero) adjustment.
• It is desirable that short pointer indicates
beyond 2 mm when long one is at 0 (zero).

15) Place zero-adjusted mounting dummy (1) and dial
gauge set on pinion dummy (2) and take
measurement between zero position and extended
dial gauge measuring tip.
NOTE
• Repeat turning back and forth of dummy
and measure distance as far as top surface
of pinion dummy accurately.
• When dial gauge measuring tip extends
from 0 (zero) position, pointer turns
counterclockwise.

16) Necessary adjusting shim thickness is the same
value as measured value by dial gauge.
17) Select adjusting shim(s) (2) closest to obtained value
from among the following available sizes and put it in
place and then press-fit rear bearing (1) to bevel
pinion (3).
Available shim thickness

20) Tighten bevel pinion nut (1) gradually with special
tool to specified torque while turning bevel pinion.
Set bearing preload of bevel pinion to specification.
NOTE
• Before taking measurement with torque
wrench, check for smooth rotation with
turning bevel pinion 15 revolutions or
more by hand.
• Be sure to tighten gradually and carefully
till specified pinion bearing preload is
obtained. Turning back overtightened
flange nuts should be avoided.
• Measure pinion bearing preload while
turning bevel pinion about 50 rpm.
• Write down measured value of bevel pinion
bearing preload for differential side
bearing shim adjustment.

21) Install differential case assembly, bearing outer
races, removed shim and differential cover,
temporarily.
NOTE
• Used left and right outer races are not
interchangeable.
• When measuring bevel pinion bearing
preload, install differential cover with
sealant not applied.

24) To measure bevel gear backlash, set dial gauge at
right angle to bevel gear tooth, fix drive bevel pinion
and read dial gauge while moving bevel gear.
If bevel gear backlash is out of specification, repeat
Step 22).

a) After cleaning 10 drive bevel gear teeth, paint them with gear marking compound evenly by using brush (1) or
sponge etc.
b) Turn gear to bring its painted part in mesh with drive bevel pinion and turn it back and forth by hand to repeat
their contact.
c) Bring painted part up and check contact pattern, referring to the following table. If contact pattern is not normal,
readjust or replace as necessary according to instruction in the table.
NOTE
Be careful not to turn drive bevel gear more than one full revolution, for it will hinder accurate check.

Transfer
General Description
Transfer DescriptionS6RW0D3301001
The transfer is mounted on transaxle case by fastening bolt with reduction drive gear in transfer and differential case in
transaxle coupled by involute spline. Driving force from transaxle is transmitted to propeller shaft through reduction
drive gear, reduction driven gear and bevel gear of transfer. As bevel gears, which change the direction of driving
torque axis to the direction of the angle with 90 degrees, hypoid gears are provided. Hypoid gears have an advantage
of preventing gear noise, at the same time, they require accurate adjustment of tooth contact and backlash.
