CAUTION:

Check that the drive pinion bearing preload is within the standard.

2.

Assemble the ring gear shaft assembly to the transfer case.

3.

Install adapter case. Refer to 

DLN-62, "M/T : Assembly"

.

4.

Rotate the companion flange at least 20 times to check for smooth operation of the bearing.

5.

Measure the total preload with a preload gauge (A) (SST:
ST3127S000).

CAUTION:

• Each rotational part should rotate smoothly with the spec-

ified gear oil.

• Disassemble the transfer assembly to check and adjust each part if outside the standard. Mea-

sure it with the adapter case oil seals removed when measuring total preload after disassembly.
Then install adapter case oil seals.

COMPANION FLANGE RUNOUT

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.

1.

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

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
micrometer. Refer to “Measuring point”.

• 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.

Dimension “E” measurement

• 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

” by the formula below.

6.

Select ring gear adjusting shim (adapter case side).

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.

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

• 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.

Dimension “F” measurement

• Measure dimension from adapter case mounting surface of

transfer case to ring gear adjusting shim mounting surface
with a depth gauge. Refer to “Measuring point”.

CAUTION:
