5) Install special tool to differential case assembly (2)

and check that preload is within specification. If
preload exceeds specified value, check if foreign
matter is caught or gear is damaged.

8) To engage drive bevel pinion and gear correctly, it is pre-required to install drive bevel pinion to differential carrier

properly by using adjusting shim as described on the followings. Shown below is relative positions of drive bevel
pinion, differential carrier and mounting dummy.

9) Install special tools with bearings (3) and flange (2)

to differential carrier (1).

NOTE
This installation requires no spacer or oil
seal.

(E): 09951–46010
(F): 09926–78311–002

10) Tighten flange nut (1) so that specified bearing

preload is obtained.

NOTE

• Before taking measurement with spring

balance (2) or torque wrench (3), check for
rotation by hand and apply small amount
of differential oil to bearings.

• On measuring preload, rotate the drive

bevel pinion about 1 rotation per 2
seconds.

Spring measure reading with special tool
20 – 40 N (2.0 – 4.0 kg, 4.4 – 8.8 lb)

11) Set dial gauge to mounting dummy and make 0

(zero) adjustment on surface plate (1).

NOTE

• When setting dial gauge to mounting

dummy, tighten screw (2) lightly. Be careful
not to overtighten it, which will cause
damage to dial gauge.

• With dial gauge set, turn dummy back and

force 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).

Special tool
(A): 09900–20607
(B): 09926–78320

12) Place zero-adjusted mounting dummy and dial

gauge set on pinion mounting dummy and take
measurement between zero position and extended
dial gauge measuring tip.

NOTE

• Repeat turning back and force 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.

• Measured value may exceed 1 mm.

Therefore, it is also necessary to know
reading of short pointer.

13) Obtain adjusting shim thickness by the following

equation.
“1 mm (0.039 in.)” is “a” + “b” (Mounting dummy size)
– “d” (Drive bevel pinion mounting distance)

14) Select adjusting shim(s) (2) closest to calculated

value from among the following available sizes and
put it in place and then press-fit rear bearing (1).

Available shim thickness
1.00, 1.03, 1.06, 1.09, 1.12, 1.15, 1.18, 1.21,1.24,

0.047 0.048, 0.049, 0.050 and 0.012 in.)

15) With new pinion spacer (3) inserted as shown in the

figure, install front bearing (5) to differential carrier
(4).

NOTE

• Make sure to use new spacer for

reinstallation.

• Apply differential oil to bearings.

16) Using special tool and plastic hammer, drive oil seal

(2) into differential carrier (1) as shown in figure.
Then apply grease “A” to oil seal lip.
