AXLE AND PROPELLER SHAFT - REAR DIFFERENTIAL ASSEMBLY 34-105

CHECK & ADJUSTMENT

1 . Check the Gear Side Clearance between
the Driving and Driven Gears
(a) Gently rotate the driven gear both clockwise
and counterclockwise by hand, until it can no
longer move.
(b) Measure the gear side clearance between the
driving and driven gears with a dial indicator.
Gear side clearance: 0.127～0.203mm

If the gear side clearance between the driving
and driven gears exceeds the repair scope,
check the engagement mark of the gears and
make proper adjustment. (Refer to "Chapter
34. Axle & transmission shaft - rear differential
assembly, check & adjustment")

NOTICE

Measure the 4 points evenly distributed on the
perimeter of the driven gear. During
measurement, ensure the head of the dial
indicator is vertical to the measured gear
surface.

2 . Check the Engagement Mark of the Driving
and Driven Gears
(a) Paint 3-4 teeth at 3 different positions of the
driven gear with red lead powder.
(b) Rote the driven gear clockwise and
counterclockwise by hand for several rounds.
(c) Check the engagement mark of the driving
and driven gears.
Position: At the center of the driven gear
surface, near the smaller end, mm or more
away from the smaller end.
Length: ≥ 60% of the tooth length

Width: ≥ 60% of the tooth width

If the engagement mark is incorrect, replace
the differential bearing and the driving gear
spacers. (Refer to "Chapter 34. Axle &
transmission shaft - rear differential assembly,
overhaul" and "Chapter 34. Axle &
transmission shaft - rear driving gear,
overhaul")
