carrier and shimming the pinion
has been developed. After gauging
a carrier, the assembler is able
to install a shim between the front
face of the pinion and its bearing
so that pinion depth can be ad-
justed to an exact required speci-
fication for best tooth contact in
each axle assembly.
Pinion depth is set with Pinion
Setting Gauge J-8619 which con-
sists of the following: (1) master
gauge, (1) indicator gauge with
dial i n d i c a t o r , (2) J-8619-10
Disks, (1) J-8619-11 Gauge Plate,
J-8619-12 P i l o t and Nut with
J-8619-13 Stud. See Figure 6-19.
Although production pinions are
marked, neither production nor
service pinions have a gauging
tooth. The pinion setting gauge
provides in affect a nominal or
zero p i n i o n as a gauging
reference.
Set up pinion setting gauge as
follows:
1. Make certain all of the gauge
parts are clean, particularly the
disks and center of the indicator
gauge; also check the centering
hole and disk pads on the master
gauge.
Setting Gauge
2. Install the J-8619-10 Disks on
the indicator gauge. Install the
small ball-tipped contact button
on the stem of the dial indicator
and mount the dial indicator on
the indicator gauge. See Figure
6-19. NOTE: When gauging for
pinion depth, the ball-tipped con-
tact button must be used on dial
indicator in order to reach Gauge
Plate J-8619-11 in carrier.
3. Place the indicator gauge on
the master gauge, as shown in
Fig. 6-20—Zeroing Pinion Setting
Gauge
Figure 6-20 so that the spring
loaded center is engaged in the
centering hole, and the inner,
large diameter portion of each
disk contacts the master gauge
pads.
4. Center the indicator c o n t a c t
button on the indicator pad and
lock the indicator by tightening
the thumb screw.
5. Hold yoke down firmly, with
both disks contacting the horizon-
tal and vertical pads on master
gauge, and set master gauge at
zero.
6. Lubricate front and rear pin-
ion bearings; then position them
in their respective races in the
carrier. While holding bearings
in place, install Gauge P l a t e
J-8619-11 in carrier on rear pin-
ion bearing inner race as shown
in Figure 6-21 and place Pilot
