(8) Apply red lead evenly to the surfaces of three or
four teeth of the crown gear. Rotate the drive pinion in
the forward and reverse directions several times. Then
remove the oil pump housing, and check the tooth con-
tact pattern.
If tooth contact is improper, readjust the backlash or
shim thickness.
Checking item Contact pattern Corrective action
Tooth contact
Tooth contact pattern is slightly shifted
toward to under no-load rotation.
[When loaded, contact pattern moves
toward heel.]
B3M0317A
Face contact
Backlash is too large.This may cause noise and chipping at
tooth ends.
B3M0319
Increase thickness of drive pinion height
adjusting shim in order to bring drive pinion
close to crown gear.
B3M0323
Flank contact
Backlash is too small.This may cause noise and stepped wear
on surfaces.
B3M0320
Reduce thickness of drive pinion height
adjusting shim in order to move drive pin-
ion away from crown gear.
B3M0324
Toe contact
(Inside end contact)
Contact areas is small.This may cause chipping at toe ends.
B3M0321
Adjust as for flank contact.
B3M0324
Heel contact
(Outside end contact)
Contact area is small.This may cause chipping at heel ends.

move smoothly.
(2) Insertion of the grip on the selector lever ... when
pushing the grip on the selector lever by hand, screw
holes should be aligned.
(3) Operation of selector lever and rod ... they should
move smoothly.
(4) Insertion of the spacer into the selector lever ... it
should be inserted lightly by finger pressure.
