Prussian Blue Dye is poisonous and
can burn skin on contact. Over
exposure to dye can cause heart and
skin problems, dizziness and
unconsciousness.
NOTE
Steps (42) through (48) adjust tooth
contact pattern.
(42)
Coat gear teeth of differential gear (3) with
Prussian blue dye.
(43)
Turn differential gear (3) to set dye pattern.
Check tooth contact pattern.
NOTE
To obtain the 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
the face width pattern that is in the
height direction of the teeth.
(44)
If tooth contact pattern is like pattern A, do
not adjust tooth contact pattern. Go to
Step (48).
(45)
If tooth contact pattern is like pattern B, add
backlash. Go to Step (34).
