pump cover to the rear case half. The oil pump
cover is aligned to the rear output shaft bearing
inner 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.FRONT OUTPUT SHAFT AND DRIVE CHAIN

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.

(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. 90).(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.
