(5) Measure the crown gear-to-drive pinion
backlash. Set magnet base on differential car-
rier. Align contact point of dial gauge with tooth
face of crown gear, and move crown gear while
holding drive pinion still. Read value indicated
on dial gauge.
NOTE:
If measured backlash is not within specified range,
repeat procedures for pinion crown gear set back-
lash adjustment and differential side bearing pre-
load adjustment.
Backlash:
0.10 Ð 0.15 mm (0.0039 Ð 0.0059 in)

15) Draw a matching mark on both differential car-
rier and holder. Remove holder one side at a time.
Replace in the original position after inserting an
O-ring and applying grease to threaded portion.

19) Checking and adjusting tooth contact of crown
gear.
(1) Apply an even coat of red lead on both
sides of three or four teeth on the crown gear.
Check the contact pattern after rotating crown
gear several revolutions back and forth until a
definite contact pattern appears on the crown
gear.
(2) When the contact pattern is incorrect, read-
just according to the instructions given in ªTooth
contact patternº.
NOTE:
Be sure to wipe off red lead completely after
adjustment is completed.
20) If proper tooth contact is not obtained, once
again adjust the drive pinion height and the differ-
ential side bearing preload (mentioned above) and
the hypoid gear backlash.
