2. Install rear pinion bearing outer race (without
shims) using installer J-7818 and driver handle J-
8092. See Figure 4B-12.
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 4B-13.

b. Alternately tighten and rotate until a torque of
7-12 lb.in. (9 Ibin. desired) new bearings or 5-7 lb.in.
(6 lb.in. desired) with used bearings is required to
rotate the gauge plate assembly.
bores of the carrier, install side bearing caps in their
respective positions and torque the bearing cap bolts
to 33 lb.ft. See Figure 4B-13.
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 #the machined sur-
face of gauging arbor J-21691-6 and tighten the
plunger set screw. See Figure 4B-14.
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 thetop of the extended
plunger. See Figure 4B- 15.
follows:
(1) Record the height block dimension as determined
in step (e).

(2) The control figure (on face of pinion) is shown in
Figure 4B-16.
If the CONTROL FIGURE (underlined) is plus,
convert the figure from millimeters to inches and
subtract from Step (1). If the CONTROL FIGURE
(underlined) is minus, convert the
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,
