Standard tooth contact pattern
1 Narrow tooth side
2 Drive-side tooth surface (the side applying powerduring forward movement)
3 Wide tooth side
4 Coast-side tooth surface (the side applying pow- er during reverse movement)
Problem
Tooth contact pattern resulting from exces-
sive pinion height
Solution
3
The drive pinion is positioned too far from the
center of the drive gear. 3Increase
the thickness of the pinion height adjusting
shim, and position the drive pinion closer to the
center of the drive gear. Also,
for backlash adjustment, position the drive
gear farther from the drive pinion.

:ient pinion height
3
The drive pinion is positioned too close to the centerIf the drive gear. 3
Decrease the thickness of the pinion height adjust-
ing shim, and position the drive pinion farther from
the center of the drive gear.
Also, for backlash adjustment, position the drive gear closer to the drive pinion.

NOTE
(1)Tooth contact pattern is a method for judging the result of the adjustme\
nt of drive pinion height and final drive gear
backlash. The adjustment of drive pinion hight and final drive gear back\
lash should be repeated until tooth contact
patterns bear a similarity to the standard tooth contact pattern.
(2) When adjustment is not able to obtain a correct pattern, it may be judg\
ed that the drive gear and drive pinion have exceed their usage limits and both gears should be replaced as a set.

2. PRESS FITTING OF OIL SEAL
(1) With the special tool, press fit the oil seal until it iswith the end of the gear carrier.
(2) Apply multipurpose grease to the oil seal lip. flush
3. INSTALLATION OF DRIVE PINION REAR BEARING OUTER RACE/A DRIVE PINION FRONT BEARING
OUTER RACE
Press-fit the drive pinion rear and front bearing outer races
into the gear carrier by using the special tool.
Caution
Be careful not to press in the outer race at an angle.
. ADJUSTMENT OF PINION HEIGHT
Adjust the drive pinion height by the following procedures: (I)
Install special tools and drive pinion front and rear
bearing inner races on the gear carrier in the sequence
shown in the illustration.
(2) Tighten the handle of the special tool until the standard value of drive pinion turning torque is obtained.
(3)
