10.

Remove and discard the seals from both halves
of the transfer case housing. See Figure 2.104.

NOTE: Use caution not to damage the seal
bores when removing the seals.

11.

The bearings need not be removed from the
case unless they are bad. Inspection will be cov-
ered in the next section of this chapter. If the
bearings do need to be removed:

11a. The right side case half contains three

bearings. See Figure 2.105.

The input shaft bearing fits in a blind bore.

The middle shaft bearing fits in a shouldered
bore that is open to the outside of the case.

The output shaft bearing fits in a shouldered
bore that is open to the outside of the case.

11b. The left side case half contains three bear-

ings: See Figure 2.106.

The input shaft bearing fits in a shouldered bore
that is open to the outside of the case.

The middle shaft bearing fits in a blind bore.

The output shaft bearing fits in a shouldered
bore that is open to the outside of the case.

11c. The bearings that fit in the blind bores may

require a blind bearing puller to remove
them from the case.

11d. The bearings that fit in the open bores

may be driven-out by their inner races
ONLY if they are not to be re-used.

11e. The cases may be evenly heated in an

oven to not more than 200 deg.f. (93
deg.c.). This will ease bearing removal
and installation, as will chilling the bear-
ings immediately prior to installation.

CAUTION: DO NOT use a torch to heat the case
halves, as the heat applied by a torch is too
uneven and may distort the case.
