2. Install rear pinion bearing outer race (without
shims) using installer J-7818 and driver handle
8092. See Figure
3. To determine the correct pinion depth setting use
the following procedures:
a. Assemble gauge plate J-21691-4, rear pinion bear-
ing (lubricated), stud J-21691-7, front pinion bearing
(lubricated), pilot washer J-21691-5 and nut into dif-
ferential carrier. See Figure

b. Alternately tighten and rotate until a torque of
7-12 lb.in. (9
desired) new bearings or 5-7 lb.in.
(6 desired) with used bearings is required to
rotate the gauge plate assembly.
Position gauging arbor J-21691-6 in side bearing
bores of the carrier, install side bearing caps in their
respective positions and torque the bearing cap bolts
to 33
See Figure
d. Position adjustable height block J-21691-3 firmly
against the face of gauge plate J-21691-4. Allow the
movable plunger to bear against
machined sur-
face of gauging arbor J-21691-6 and tighten the
plunger set screw. See Figure
e. Remove the adjustable height block and use a 1”
to 2” micrometer to measure the distance from the
bottom of the height block to
of the extended
plunger. See Figure
Select the correct pinion depth shim thickness as
follows:
(1) Record the height block dimension as determined
in step

(2) The control figure (on face of pinion) is shown in
Figure
If the CONTROL FIGURE (underlined) is plus,
convert the
from millimeters to inches and
subtract from Step (1). If the CONTROL FIGURE
(underlined) is minus, convert the
figure
from milli-
meters to inches and add to Step (1).
(3) Record the result from Steps (1) and (2).
(4) Subtract from Step (3) the nominal figure 1.468.
(5) The difference between Steps (3) and (4) is thick-
ness of shims required to set the pinion,
