8. INSTALLATION OF TRANSFER CASE ADAPTER SUB +=GASSEMBLY
-Using a brush, apply a thin even coat of machine blue orminium to both tooth surfaces of the driven bevel gear.
6. INSTALLATION OF SPACERInstall the spacer which has been used so far.
5. INSTALLATION OF TRANSFER CASE SUB ASSEMBLY
(1) Tighten the transfer case adapter sub assembly on the
transfer case sub assembly to the specified torque.
\
-;--.(2) Using the special tool, turn the drive bevel gear shaft
one turn each in the direction of normal and reverse
rotation.Caution
Do not rotate the drive bevel gear shaft more thanone turn
as it cause a blurred tooth contact pattern.
MB991144(3) Make sure that the contact pattern of the driven bevel
gear teeth is correct.
NOTE
See Tooth Contact Adjustment Procedure on next pagefor the standard tooth contact pattern.

AUTOMATIC TRANSAXLE - Transfer Assembly 21-335(4) Check to see if the backlash between the drive and
driven bevel gears is up to specification.Standard value

TOOTH CONTACT ADJUSTMENT PROCEDURE
1. Standard tooth contact pattern
A: Small end
B: Drive side tooth surface
(The side receiving force in forward motion)
C: Big end
D: Coast side tooth surface
(The side receiving force in reverse motion)
2. Tooth contact pattern when driven bevel gear is too
high
Possible cause:The driven bevel gear is too close to the drive bevel gear.
Remedy:Use a thicker spacer for the driven bevel gear mount
adjustment so that the driven bevel gear is further away
from the drive bevel gear.
3. INSTALLATlON OF EXTENSION HOUSING ASSEMBLY
Apply sealant to the flange surface of the adapter and installthe housing.
Specified sealant: Mitsubishi genuine Part No.997740Caution
or equivalentSqueeze out
the sealant from the tube uniformly
without excess or discontinuities.

3. Tooth contact pattern when driven bevel gear is too
low
Possible cause:A-kThe driven bevel gear is further away from the drive bevel
~gear than necessary.
Remedy:Use a thinner spacer for the driven bevel gear mount
adjustment so that the driven bevel gear is closer to the
drive bevel gear.
NOTE(1) If correct tooth contact cannot be obtained by replace-
ment of spacer for adjusting driven bevel gear mount,
change the spacers for adjustment of drive bevel gear
preload and drive bevel gear mount adjustment to those4of appropriate thickness as described below and adjust
-.’the tooth contact again.
lIf the driven bevel gear height is still too small whenthe thinnest spacer for driven bevel gear mount
adjustment
[0.13 mm (.005 in.)] is used;
Change the spacer for drive bevel gear mount
adjustment to the next thicker one and change the
spacer for drive bevel gear preload adjustment to
the next thinner one.
lIf the driven bevel gear height is still too large whenthe thickest spacer for driven bevel gear mount
adjustment
[0.52 mm (021 in.)] is used;
Change the spacer for drive bevel gear mount
adjustment to the next thinner one and change the
spacer for drive bevel gear preload adjustment to
the next thicker one.
Repeat above steps until standard tooth contact
pattern is obtained.
(2) If the tooth contact pattern cannot be brought close to
the standard pattern by the adjustment described
above, replace the drive bevel gear and driven bevel
gear as a set and adjust the tooth contact again.
