ately sized pin to retain the position (Fig. 98).
(2) Position shift lever in vehicle.
(3) Install the bolts to hold the shifter mechanism
to the floor pan.
(4) Raise vehicle.
(5) Verify that the transfer case is still in the 2H
position. The 2H detent position on the transfer case
shift arm is the second position from full forward.(6) Install trunnion to shift lever, if necessary.
(7) Install shift rod to trunnion, if necessary.
(8) Tighten the shift rod lock bolt to 10 N´m (90
in.lbs.).
(9) Remove the shifter adjustment locating pin
from the adjustment channel and the locating hole.
(10) Lower vehicle.
(11) Install the transfer case shifter console.
(12) Install the shifter boot and the shifter knob

ADJUSTMENTS
ADJUSTMENT - SHIFT LEVER
(1) Move shift lever into 2H position.
(2) Raise vehicle.
(3) Loosen shift rod lock bolt at trunnion.
(4) Check shift rod fit in trunnion. Be sure rod
does not bind in trunnion. Lubricate the shift rod
and trunnion if necessary.
(5) Verify that transfer case shift lever is in 2H
detent position. The 2H detent position on the trans-
fer case shift arm is the second position from full for-
ward.
(6) Align the adjustment locating hole on the lower
shifter lever with the adjustment channel on the
shifter bracket assembly (Fig. 99).(7) Insert an appropriately sized pin through into
the adjustment channel and through the locating
hole to hold the shifter in the correct position.
(8) Tighten shift rod lock bolt to 10 N´m (90 in.
lbs.) torque.
(9) Remove the locating pin from the adjustment
channel and locating hole.
(10) Check shift linkage operation. Be sure trans-
fer case shifts into and operates properly in all
ranges.

OIL PUMP AND REAR CASE
(1) Remove rear case-to-front case bolts (Fig. 11).
(2) Loosen rear case with pry tool to break sealer
bead. Insert tool in slot at each end of case (Fig. 12).(3) Unseat rear case from alignment dowels.
(4) Remove rear case and oil pump assembly from
front case (Fig. 13).
CAUTION: Do not remove the bolts holding the oil
pump cover to the rear case half. The oil pump
cover is aligned to the rear output shaft inner bear-
ing race and will become mis-aligned if the bolts
are loosened. If the transfer case failure has gener-
ated any debris which may have become trapped in
the oil pump. the rear case and oil pump assembly
MUST be replaced.
(5) Remove the oil pump pickup tube.

OIL PUMP AND REAR CASE
Lubricate the oil pump components with transmis-
sion fluid before installation. Prime the oil pickup
tube by pouring a little oil into the tube before instal-
lation.
CAUTION: Do not remove the bolts holding the oil
pump cover to the rear case half. The oil pump
cover is aligned to the rear output shaft inner bear-
ing race and will become mis-aligned if the bolts
are loosened. If the transfer case failure has gener-
ated any debris which may have become trapped in
the oil pump. the rear case and oil pump assembly
MUST be replaced.
(1) Install new o-ring in pickup tube inlet of oil
pump.
(2) Insert oil pickup tube into the oil pump.
(3) Apply bead of MopartGasket Maker, or equiv-
alent, to mating surface of front case. Keep sealer
bead width to maximum of 3/16 inch. Do not use
excessive amount of sealer as excess will be displaced
into case interior.
(4) Align oil pump with mainshaft and align shift
rail with bore in rear case. Then install rear case and
oil pump assembly (Fig. 73).
(5) Install 4-5 rear case-to front case bolts (Fig. 74)
to hold rear case in position. Tighten bolts snug but
not to specified torque at this time.
CAUTION: Verify that shift rail, and case alignment
dowels are seated before installing any bolts. Case
could be cracked if shaft rail or dowels are mis-
aligned.(6) Apply LoctiteŸ 242 to remainder of rear case-
to-front case bolt threads and install bolts. Tighten
bolts to 20-27 N´m (15-24 ft. lbs.),
(7) Install rear output bearing snap-ring (Fig. 75)
to output shaft.
SEAL BOOT AND SHIFT MOTOR ASSEMBLY
(1) Install the front output shaft seal slinger with
Installer 8840. Install the slinger onto the shaft until
the tool contacts the rear of the output shaft.
(2) Install a new seal boot clamp onto the seal
boot.
(3) Install the seal boot and clamp onto the slinger
hub and tighten the clamp with Crimp Tool
C-4975-A.
