1.

Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft bolt holes).

2.

Rotate the companion flange to check for runout.

3.

Fit a test indicator to the inner side of the companion flange
(socket diameter).

4.

Rotate the companion flange to check for runout.

5.

Follow the procedure below to adjust if runout value is outside
the repair limit.

CAUTION:

Replace collapsible spacer to check and adjust each part
when companion flange is adjusted or replaced.

a.

Check for runout while changing the phase between companion flange and drive pinion in 90

°

 steps. Then

search for the minimum point.

b.

Replace companion flange if runout value is still outside the limit after the phase has been changed.

c.

Adjust assembly status of the drive pinion bearings and drive pinion, or replace drive pinion bearings if
runout is outside the standard after the companion flange is replaced.

Dimension “A” measurement

• Measure dimension from transfer case mounting surface of

adapter case to adapter case edge surface with a pair of ver-
nier calipers and straightedge. Refer to “Measuring point”.

Dimension “B” measurement

• Measure dimension from ring gear adjusting shim mounting

surface of adapter case to adapter case edge surface with a
pair of vernier calipers and straightedge. Refer to “Measuring
point”.

Dimension “C” measurement

• Measure the diameter of drive pinion bearing (rear side)

mounting area of transfer case with a pair of vernier calipers.
Refer to “Measuring point”.

CAUTION:

Never damage transfer case.

Dimension “D” measurement

• Measure dimension from adapter case mounting surface of

transfer case to drive pinion bearing (rear side) mounting sur-
face with a pair of vernier calipers and straightedge. Refer to
“Measuring point”.

CAUTION:

• Never damage transfer case.
• Consider the thickness of a straightedge.

• Measure dimension from outer race edge surface of ring gear

shaft bearing (adapter case side) to inner race edge surface
with a pair of vernier calipers. Refer to “Measuring point”.

2.

Calculate dimensions “M” and “N” by the formula below.

3.

Convert the dimensions “E”, “M” and “N” according to the standards below.

4.

Check dimension “Z” (machining difference) on the ring gear
back surface.
NOTE:
Dimension “Z” indicates difference between optimum engage-
ment and the standard dimensions in increments of 0.01 mm
(0.0004 in) written on the ring gear back surface.

5.

Calculate the thickness of the ring gear adjusting shim (adapter
case side) “T

1

” by the formula below.

6.

Select ring gear adjusting shim (adapter case side). For selecting adjusting shim, refer to the latest parts
information.

CAUTION:

• Only one adjusting shim can be selected.
• Select the closest one, favoring thicker over thinner when necessary if no adjusting shim with

the calculated value is available.

Ring Gear Adjusting Shim (Transfer Case Side)

1.

Measure the dimensions of each measuring point with the following procedure:

Dimension “C” measurement

• Measure the diameter of drive pinion bearing (rear side)

mounting area of transfer case with a pair of vernier calipers.
Refer to “Measuring point”.

CAUTION:

Never damage transfer case.

Dimension “D” measurement

SDIA3109J

Dimension “M” = “A” – “B”

Dimension “N” = “C” 

×

 0.5 mm (0.020 in) + “D”

“E”

: Actual value regarding 20.00 mm (0.7874 in) as 0 in increments of 0.01 mm (0.0004 in).

“M”

: Actual value regarding 13.90 mm (0.5472 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).

“T
