AUTOMATIC TRANSMISSION
26.Transfer Clutch
A: REMOVAL
1) Remove the transmission assembly from vehi-
cle. <Ref. to 5AT-38, REMOVAL, Automatic Trans-
mission Assembly.>
2) Remove the extension case, and then remove
the transfer clutch. <Ref. to 5AT-72, REMOVAL,
Extension Case & Intermediate Case.> <Ref. to
5AT-73, DISASSEMBLY, Extension Case & Inter-
mediate Case.>
B: INSTALLATION
1) Select the rear drive shaft shim. <Ref. to 5AT-74,
ADJUSTMENT, Transfer Clutch.>
2) Select the driven plate No. 3. <Ref. to 5AT-74,
ADJUSTMENT, Transfer Clutch.>
3) Install the extension case and intermediate
case. <Ref. to 5AT-72, INSTALLATION, Extension
Case & Intermediate Case.>
4) Install the transmission assembly into vehicle.
<Ref. to 5AT-42, INSTALLATION, Automatic
Transmission Assembly.>
C: INSPECTION
• Inspect the drive plate facing for wear and dam-
age.
• Inspect the snap ring for wear; return spring for
permanent distortion, breakage and deformation.
• Check that the D-ring is not damaged.
• Inspect the extension end play and adjust it to
within specifications. <Ref. to 5AT-74, ADJUST-
MENT, Transfer Clutch.>
D: ADJUSTMENT
1) Insert the rear drive shaft into the reduction drive
gear and center differential assembly.
2) Using the ST, measure the depth "A", which is
from mating surface of extension case to ball bear-
ing outer ring contact surface.

3) Using the ST, measure the height "B" from the
intermediate case mating surface to ball bearing
outer ring contact surface.
ST 398643600
4) Calculation formula:
When clearances are 0.05 mm (0.0020 in):
T (mm) = A " (B " 0.28) " 0.05
[T (in) = A " (B " 0.011) " 0.0020]
When clearances are 0.25 mm (0.0098 in):
T (mm) = A " (B " 0.28) " 0.25
[T (in) = A " (B " 0.011) " 0.0098]
A: Depth from end of extension case to ball bearing
outer ring contact surface
B: Height from end of intermediate case to ball
bearing outer ring contact surface
T: Shim thickness
0.05 — 0.25 mm (0.0020 — 0.0098 in)
NOTE:
AT-01963
Calculation formula for "T" is applied when measur-
ing using ST (398643600 GAUGE). When not us-
ing ST, apply following.
When clearances are 0.05 mm (0.0020 in):
T (mm) = (A " #) " ((B " $) " 0.28) " 0.05
[T (in) = (A " #) " ((B " $) " 0.011) " 0.0020]
When clearances are 0.25 mm (0.0098 in):
T (mm) = (A " #) " ((B " $) " 0.28) " 0.25
[T (in) = (A " #) " ((B " $) " 0.011) " 0.0098]
