TM 9-2320-364-34-4
25-74
25-15. AXLE NO. 1 AND 5 DIFFERENTIAL ASSEMBLY REPAIR (CONT).
NOTE
To obtain correct tooth
contact pattern two
considerations must be
observed: One is the
lengthwise contact pattern
that is in the length
direction of the teeth, the
other is face width pattern
that is in height direction of
teeth.
A correct gear pattern for a
used pinion shaft and
differential and bevel gear is
clear of the toe and centers
evenly along the face of gear
tooth, but can be any length
and shape and is acceptable
as long as pattern does not
run off gear tooth at any
point.
(44)
Check tooth contact pattern on differential
gear (2).
(45)
If tooth contact pattern is like pattern A, do
not adjust tooth contact pattern. Go to
Step (47).
(46)
If tooth contact pattern is like pattern B, add
backlash. Refer to Step (35).
