and must be installed with the chamfered side toward
the pinion head.
(1) Place the selected spacer (Paragraph 8) and the
bearing on the pinion. Use installing Sleeve Tool C-
3717, to press bearing on pinion, (Fig. 55).
(2) Hold the pinion in carrier and install the origi-
nal preload washer (chamfered side toward shoulder),
front bearing, yoke and nut on the pinion.
(3) Turn the housing to bring the nose of the car-
rier up. Tighten the nut to 240 foot-pounds (mini-
mum), with torque wrench tool C-485, using holding
Tool C-3281, on the yoke to hold the assembly in sev-
eral positions to make a complete revolution while
tightening. Remove the holding tool and rotate the
assembly several turns in both directions to align the
bearing rollers.
(4) Use an inch-pound torque wrench Tool C-685
to
measure the preload. Accurate readings can be ob-
tained only with the nose of the carrier up. With the
handle of the wrench floating, take reading when the
wrench is moving through several
full
turns. Correct
preload is 15 to 25 inch-pounds.

ies during rotation indicates a binding condition
which should be corrected. Use thinner washer to in-
crease preload and thicker washer to decrease pre-
load.
Always
perform Steps 3 and 4 in exactly the
same manner each time to obtain accurate preload
readings. Preload washers are available in .001 varia-
tions from .074 to .lo6 inch.
(5) When the preload is correct, remove the nut
and yoke.
(6) Apply a thin film of sealing compound to the
inner bore of the carrier in the area of the pinion
seal.
(7) Install the pinion oil seal (lip toward the pinion
head) with Tool C-3719 to space the seal flange the
proper distance in the carrier housing bore, (Fig. 56).
(8) Install the yoke, using installing Tool C-3718
and holding Tool C-3281, (Fig. 57).
(9) Remove the tools and install the washer
(cupped side toward pinion head) and nut. Tighten
nut to 240 foot-pounds torque.
