sealing compound (item 23, App B). Press the seal and retainer against the shoulder of the pinion cage

with a seal driver.

(14)

Press the yoke and washer against the forward bearing and install the pinion shaft nut.

Torque to 700-900 Ib-ft (949-1220 N•m).

b. Install the Pinion and Cage Assembly.

(1) Original Gear Set.

(a)

If the original pinion and drive gear are to be reassembled into the carrier, use the same

shim pack, if reusable, between the pinion bearing cage and the carrier. Otherwise, use a new shim pack of

the same thickness.

NOTE

Use a minimum of three shims per pack.

(b)

Install the correct shim pack. Locate thin shims on both sides for maximum sealing

ability.

(c)

Place the pinion and cage assembly (with shims) into the carrier and tap into position

with a soft mallet.

(d)

Install capscrews. Torque to 85-115 Ib-ft (1 15-156 N•m).

NOTE

After the differential and gear assembly

is installed into the carrier, make a gear

tooth contact check.

(2) New

Gear Set.

NOTE

If the pinion or drive gear require replace-

ment, both must be replaced in matched

sets.

(a)

Before installing a new pinion and gear set, check and compare the matching number

of both the pinion and drive gear; they must be the same. An example of this number would be M29 or

any combination of a letter and number marked on the nose of the pinion and on the front face of the

drive gears.
