change required to obtain desired starter shim
thickness.
For example, if the old pinion is marked -3 and the
new pinion +2, chart procedure would be as follows:
Refer to Old Pinion Marking column at left side of chart
and locate -3 figure in this column. Then read to right,
across chart, until under +2 figure in New Pinon Mark
ing column. Box where the two columns intersect will
provide amount of shim thickness required. In this case,
the number in the intersecting box is -0.005 (0.12mm)
which represents the amount to be subracted from the
original shim thickness. If the box number had been a +
figure, this amount would be added to the original shim
thickness.
CAUTION: Front axle differentials use an oil slinger
between the pinion rear bearing and the pinion head
(fig. 2F-1). This slinger must be ins tailed in order to
measure and adjust pinion depth correctly.
(1) Measure thickness of pinion depth shim re
moved during disassembly.
(2) Note pinion depth variance numbers on old and
new pinion gears.
(3) Refer to pinion variance chart and determine
amount to be added to or subtracted from original shim
to arrive at starter shim thickness.
CAUTION: Do not use or assume that the starter shim
thickness will be the final shim setting. An actual pinion
depth measurement must be performed and the final
shim thickness adjusted as necessary.
(4) Install pinion front bearing cup in housing bore
using Driver Handle J-7079-02 and Installer J-25101.
(5) Install starter shim in rear bearing bore of hous
ing. Be sure shim is centered in cup bore. If shim is
chamfered, chamfer must face toward housing
bore—not toward pinion head.
(6) Install pinion rear bearing cup in housing bore.
On Model 30 axles, install cup using Driver Handle J-
7079-02 and Installer J-25101. On Model 44 and 60 axles,
install cup using Driver Handle J-25122 and Installer J-
25157.
(7) On front axle differentials, install oil slinger on
pinion gear. Be sure slinger is seated on pinion head
before installing rear bearing.
(8) Install rear bearing on pinion. On Model 30 axles
install cup using Installer Sleeve J-5590 (fig. 2F-53). On
Model 44 and 60 axles, install bearing using Installer
Sleeve J-24433 (fig. 2F-53).
(9) Install pinion gear in axle housing.
(10) Install pinion front bearing, pinion yoke,
washer, and original pinion nut on pinion. Tighten nut
only enough to remove end play and provide 10 to 15
inch-pounds (1 to 2 N«m) of drag torque when pinion is
rotated.

NOTE: Do not install the pinion seal, slinger, or dust
cap at this time. The pinion will be removed after meas
uring and adjusting pinion depth.
(11) Note pinion depth variance marked on pinion
gear. If number is preceded by a plus (+) sign, add that
amount (in thousands or millimeters) to standard set
ting for axle model being overhauled. If number is pre
ceded by a minus (-) sign, subtract that amount (in
thousands or millimeters) from standard setting. Result
of addition or subtraction is desired pinion depth. Re
cord this figure for further reference.
NOTE: If the gear is marked 0 (zero), use the standard
setting.
(12) Assemble Gauge Arbor J-5223-4 and Discs. On
Model 30 axles, use Discs J-5223-26. On Model 44 and 60
axles, use Discs J-5223-25.
(13) Install assembled arbor and discs in differential
bearing cup bores (fig. 2F-54). Be sure discs are firmly
seated in bearing cup bores.
(14) Install differential bearing caps over discs and
tighten cap bolts securely, but not to specified torque.
(15) Remove standard plunger from Gauge Block J-
5223-20 and install Plunger J-5223-27.
(16) Compress plunger completely and tighten gauge
block thumbscrew securely.
(17) Install Gauge Block J-5223-20. Position block so
plunger is directly under Arbor J-5223-4 and flat surface
on anvil side of block is seated on end face of pinion (fig.
2F-54).
