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.
