Adjustment
Check gear tooth contact as follows.
1) After cleaning tooth surface of bevel gear (1), paint them
with gear marking compound evenly by using brush or
sponge etc.
NOTE:
When applying red lead paste to teeth, be sure to paint
tooth surfaces uniformly. The paste must not be too dry
or too fluid.
2) Turn gear to bring its painted part in mesh with bevel pinion
and turn it back and forth by hand to repeat their contact.
3) Bring painted part up and check contact pattern referring to
"Bevel gear tooth contact table" in this section.
If contact pattern is not normal, readjust or replace as neces-
sary according to instruction in table.
NOTE:
• Be careful not to turn bevel gear more than one full
revolution, for it will hinder accurate check.
• If bevel gear back lash and bevel pinion shims are
adjusted properly, correct tooth contact should be pro-
vided.
If correct tooth contact is not provided even when they
are adjusted properly, however, there may be an
abnormal condition in worn tooth, transfer case or
retainer. Check each component and replace as neces-
sary.
