Component Inspection
•Check companion flange for wear or damage.
•Check bearings for wear or discoloration.
•Check differential carrier for cracks.
•Check drive bevel pinion and drive bevel gear for wear or cracks.
•Check differential gears, pinions and pinion shafts for wear or damage.
•Check differential gear spline for wear or damage.
Sub-Assembly Adjustment and Reassembly
Judging from faulty conditions noted before disassembly and
what is found through visual check of bearing and gear tooth etc.
after disassembly, prepare replacing parts and proceed to reas-
sembly according to procedures as described below.
CAUTION:
Drive bevel gear and pinion must be replaced as a set
when either replacement becomes necessary.
When replacing taper roller bearing, replace as inner
race & outer race assembly.

Drive bevel pinion
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.

Assembling Unit
1) Place bearing outer races on their respective bearings.
Used left and right outer races are not interchangeable.
2) Install case assembly in carrier.
3) Install side bearing adjusters on their respective carrier,
making sure adjuster are threaded properly.
4) Align match marks (1) on cap and carrier. Screw in 2 side
bearing cap bolts 2 or 3 turns and press down bearing cap
by hand.
5) Tighten cap bolts (provisional torque).
Tightening torque
Bearing cap bolt (Provisional torque) (a) :
15 N·m (1.5 kg-m, 11.0 lb-ft)
6) Tighten both bearing adjusters (2) so as to obtain specified
gear backlash and at the same time, obtain preload of side
bearing.
Standard backlash
: 0.13 – 0.18 mm (0.005 – 0.007 in.)
Special tool
(A) : 09930-40120
(B) : 09930-40113
(C) : 09900-20701
NOTE:
If bearing cap does not fit tightly on carrier, side bearing
adjuster is not threaded properly. Reinstall adjuster.
NOTE:
Be sure to apply measuring tip of dial gauge at right
angles to convex side of tooth.
As a practical measure the following would be recom-
mended to obtain specified backlash and side bearing
preload at the same time.
–Obtain specified backlash by turning both adjusters
inward lightly.
–Tighten both adjusters further by one notch at a
time.
Measure at least 4 points on drive bevel gear periph-
ery.

7) Measure preload of pinion bearing with spring balance (1) or
torque wrench (2) and check composite preload of pinion
bearing and side bearing.
Composite preload of pinion bearing and side bearing
: 1.1 – 2.0 N·m (11.0 – 20.0 kg-cm, 9.5 – 17.4 lb-in.)
Spring measure reading with special tool
: 19.5 – 35.5 N (1.95 – 3.55 kg, 4.30 – 7.83 lb)
Special tool
(D) : 09922-76560
8) Torque bearing cap bolts (2) to specification and install bear-
ing lock plates.
Tightening torque
Lock plate bolt (b) : 12 N·m (1.2 kg-m, 9.0 lb-ft)
Bearing cap bolt (c) : 85 N·m (8.5 kg-m, 61.5 lb-ft)
9) As final step, check gear tooth contact as follows.
a) After cleaning 10 drive bevel gear teeth, paint them with
gear marking compound evenly by using brush 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 con-
tact.
c) Bring painted part up and check contact pattern, referring
to following chart. If contact pattern is not normal, readjust
or replace as necessary according to instruction in chart. NOTE:
Before taking measurement with spring balance (1) or
torque wrench (2), check for smooth rotation by hand.
On measuring preload, rotate the drive bevel pinion
about 1 rotation per 2 seconds.

NOTE:
Be careful not to turn drive bevel gear more than one full
