DRIVE GEAR BACKLASH

ACX01034AB

1. With the drive pinion locked in place, use a dial

gauge to measure the drive gear backlash in four
or more places on the drive gear.

Standard value: 0.11

− 0.16 mm

2. If the backlash is not within the standard value,

adjust the final drive gear backlash (Refer to ).

3. After the adjustment, inspect the final drive gear

tooth contact.

DRIVE GEAR RUNOUT

ACX01036 AB

1. Measure the drive gear runout at the shoulder on

the reverse side of the drive gear.

Limit: 0.05 mm

2. When the runout exceeds the limit value, check

for foreign material between drive gear rear side
and differential case, and for loose drive gear
installation bolts.

3. When check (2) gives normal results, reposition

drive gear and differential case and remeasure.

4. If adjustment is impossible, replace differential

case, or replace drive gear and pinion as a set.

DIFFERENTIAL GEAR BACKLASH

AC102885

Wedge

Side gear
spacer

1. Insert a wedge between the side gear and the

pinion shaft to lock the side gear.

2. While locking the side gear with the wedge,

measure the differential gear backlash with a dial
indicator on the pinion gear.
Use the measurement procedure for the other
pinion gear.

Standard value: 0.01

− 0.250 mm

3. If the backlash exceeds the standard value, adjust

it by replacing the side gear spacers.

4. If adjustment is not possible, replace the side

gears and pinion gears as a set.

DRIVE GEAR TOOTH CONTACT
Check the tooth contact of drive gear by following the
steps below.

ACX01037 AB

1. Apply a thin, uniform coat of machine blue to both

surfaces of the drive gear teeth.

FRONT AXLE

26-40

CAUTION

If the drive gear is rotated too much, the tooth
contact pattern will become unclear and difficult
to check.

AC102888

MB990939

2. Insert special tool remover bar (MB990939)

between the differential carrier and the differential
case, and then rotate the companion flange by
hand (once in the normal direction, and then once
in the reverse direction) while applying a load to
the drive gear so that the revolution torque
(approximately 2.5

− 3.0 N⋅m) is applied to the

drive pinion.

3. Check the tooth contact condition of the drive gear

and drive pinion.

Standard tooth contact pattern

Problem

Solution

1. Narrow tooth side
2. Drive-side tooth surface

(the side applying power during forward

movement)
3. Wide tooth side
4. Coast-side tooth surface

(the side applying power during reverse

movement)

ACX01039 AF

Tooth contact pattern resulting
from excessive pinion
height

AC107260

The drive pinion is positioned too
far from the centre of the drive
gear.

AC107261AB

Increase the thickness of
the drive pinion rear shim,
and position the drive pinion
closer to the centre of the
drive gear. Also, for
backlash adjustment,
position the drive gear
farther from the drive
pinion.

Tooth contact pattern resulting
from insufficient pinion
height.

AC107262

The drive pinion is positioned too
close to the centre of the drive
gear.

AC107263

Decrease the thickness of
the drive pinion rear shim,
and position the drive pinion
farther from the centre of
the drive gear. Also, for
backlash adjustment,
position the drive gear
closer to the drive pinion.

NOTE: Check the tooth contact pattern to confirm
that the adjustments of the pinion height and
backlash have been done properly. Continue to
adjust the pinion height and backlash until the
tooth contact pattern resembles the standard pat-

tern. If, even after adjustments have been made,
the correct tooth contact pattern cannot be
obtained, it means that the drive gear and the
drive pinion have become worn beyond the allow-
able limit. Replace the gear set.
