• Select the closest one, favoring thicker over thinner when necessary if no adjusting shim with

the calculated value is available.

Drive Pinion Adjusting Shim

1.

Check the dimension “U” (machining difference) between old
and new drive pinions when hypoid gear set (drive pinion and
ring gear) has been replaced.
(Assemble new drive pinion adjusting shims with the same thick-
ness as the ones removed prior to disassembly or removed
drive pinion adjusting shims when reusing the hypoid gear set.)
NOTE:
Dimension “U” indicates the difference between optimum
engagement and the standard dimensions in increments of 0.01
mm (0.0004 in). It is written on the gear end of the drive pinion
for reference.

2.

Calculate the thickness of the drive pinion adjusting shim “T” by
the formula below.

Select drive pinion adjusting shim.

“I”

: Actual value regarding 119.40 mm (4.70 in) as 0 in increments of 0.01 mm (0.0004 in).

“J”

: Actual value regarding 16.25 mm (0.6398 in) as 0 in increments of 0.01 mm (0.0004 in).

“N”

: Actual value regarding 55.00 mm (2.1654 in) as 0 in increments of 0.01 mm (0.0004 in).

CAUTION:

• Only one adjusting shim can be selected.
• Select the closest one, if no adjusting shim with the calculated value is available.

Inspection After Disassembly

INFOID:0000000010288367

Check items below. If necessary, replace them with new ones.

GEAR AND SHAFT

Check gear face and shaft for wear, cracks, damage, and seizure.

CAUTION:

Replace ring gear and drive pinion as a set (hypoid gear set) if any malfunction is detected on the ring
gear or drive pinion.

BEARING

Check for seizure, peeling, wear, corrosion, sticking, unusual noise, roughness in hand turning, and other
damage.

CAUTION:

Always replace inner race and outer race as a pair when replacing the bearing.

SHIM

Check for seizure, damage, and unusual wear.

CASE

Check the bearing mounting surface for wear, cracks and damages.
