the rear output shaft ball bearings. Do not drive the
ball bearings into place with a hammer.





32. Install the rear output shaft retaining ring.
33. Place the oil pump in its specified position.
34. Secure the oil pump strainer to the rear cover and
tighten the bolts to the specified torque.

35.
Apply Loctite FMD 127 to the mating surfaces of the
rear cover and the transfer case. Be sure that the
Loctite is evenly applied to the inside surfaces of the
bolt holes with no gaps.

TRANSFER CONTROL SYSTEM 7D1-49
Step 4-3: (Same procedure as the step 3-3)
Stop the vehicle (close the accelerator and decrease the engine speed to L4: 3000rpm V6: 2000rpm or below).
(In case of AT): Set the transmission select lever to the N position.
(In case of MT): Set the transmission lever to the neutral position (stepping on the clutch lever is recommended).
Push the 4H button.
If shifting is not complete (indicator flashes at 2Hz), go to step 4-1.

5. When shifting from 4H or 4L to neutral
(Same procedure is required when shifting from 2H but in such a case, requirements for shifting from
2H to 4H are also applied.)
5-1 Neutral indicator continues flashing at 2Hz The neutral indicator continues flashing at 2Hz until 4H (4L) is completely separated in the transfer. If torsional
torque has accumulated between the transmission and road surface, separation may be difficult.
Step 5-1:
If the operation is not complete, execute step 7 for confirmation.
(In case of AT): Set the transmission select lever to the D position. After confirming that the gears are at the neutral position, return the lever to the N
position.
(In case of MT): Set the transmission lever to a vehicle running position and engage the clutch gently. After confirming that the gears are at the neutral position, return the lever to the
neutral position
5-2 When the neutral indicator flashes at 4Hz
As in the case of shifting from 4L to 4H, restriction is imposed to the operation from 4L or 4H (including 2H). If
the transmission lever is at a running range and engine speed is high (L4: 3000rpm, V6: 2000rpm or more)
while the vehicle is running, operation from the 4L or 4H (including 2H) of the transfer to the neutral is
impossible (restriction on operation).
Step 5-2:
Stop the vehicle.
(In case of AT): Set the transmission select lever to the N (or P) position.
(In case of MT): Set the transmission lever to the neutral position (at this time, stepping on the clutch is recommended).
Keep pushing the 2H and 4L button for 10 seconds.
Follow the start procedure for confirmation. (Confirmation of drive force is not transferred; same as in
step 5-1)
After the confirmation, set the transmission to the neutral position in the case of MT or to the neutral
position in the case of AT.

SPLICING WIRE
Open the Harness
If the harness is taped, remove the tape.
To avoid wire insulation damage, use a sewing “seam ripper”
(available from sewing supply stores) to cut open the harness.
If the harness has a black plastic conduit, simply pull out the
desired wire.
Cut the wire
Begin by cutting as little wire off the harness as possible.
You may need the extra length of wire later if you decide to cut
more wire off to change the location of a splice.
You may have to adjust splice locations to make certain that
each splice is at least 1-1/2” (40 mm) away from other splices,
harness branches, or connectors.
Strip the insulation
W hen replacing a wire, use a wire of the same size as the
original wire.
Check the stripped wire for nicks or cut strands.
If the wire is damaged, repeat the procedure on a new section
of wire.
The two stripped wire ends should be equal in length.



Crimp the Wires
Select the proper clip to secure the splice.
To determine the proper clip size for the wire being spliced,
follow the directions included with your clips.
Select the correct anvil on the crimper.
(On most crimpers your choice is limited to either a small or
large anvil.)
Overlap the two stripped wire ends and hold them between
your thumb and forefinger.
Then, enter the splice clip under the stripped wires and hold it
in place.



•
Open the crimping tool to its full width and rest one handle
on a firm flat surface.
• Center the back of the splice clip on the proper anvil and
close the crimping tool to the point where the back of the
splice clip touches the wings of the clip.
• Make sure that the clip and wires are still in the correct
position. Then, apply pressure until the crimping tool closes.



Before crimping the ends of the clip, be sure that:
• The wires extend beyond the clip in each direction.
• No strands of wire are cut loose.
• No insulation is caught under the clip.
Crimp the splice again, once on each end.
Do not let the crimping tool extend beyond the edge of the clip
or you may damage or nick the wires.
