TOOTH CONTACT PATTERN
NOTE:
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 abnor-
mal condition in worn tooth, transfer case or retainer.
Check each component and replace as necessary.
DIAGNOSIS AND REMEDY
NORMAL
HIGH CONTACT
Pinion is positioned too fat from the
center of drive bevel gear.
1) Decrease thickness of bevel pinion
shim and position pinion closer to
gear center.
2) Adjust drive bevel gear backlash to
specification.
LOW CONTACT
Pinion is positioned too close to the
center of drive bevel gear.
1) Increase thickness of bevel pinion
shim and position pinion farther
from gear center.
2) Adjust drive bevel gear backlash to
specification.
These contact patterns indicate that the "offset" of
reduction driven gear is too much or too little. The rem-
edy is to change the division of the bevel gear shim(s).
