2. TRANSFER CASE
Assembly of transfer case is in the reverse order of disas-
sembly. Do the following:
1) Assembly of reverse check sleeve
(1) Install reverse accent shaft

F, check cam
D, return
spring

Eand check spring
Conto reverse check
sleeve.
NOTE:
Be sure the bent section of reverse check spring is posi-
tioned in the groove in check cam.
(2) Hook the bent section of reverse check spring over
reverse check plate

B.
(3) Rotate cam so that the protrusion of reverse check
cam is at the opening in plate.
(4) With cam held in that position, install plate onto
reverse check sleeve and hold with snap ring

A(Inner-
28).
(5) Position O-ring

G(35.4 x 1.5) in groove in sleeve.
B3M0048A
CAUTION:
Make sure the cutout section of reverse accent shaft
is aligned with the opening in reverse check sleeve.
Spin cam by hand for smooth rotation.
If it does not return properly, replace reverse check
spring.
Move cam and shaft all the way toward plate and
release.
If cam does not return properly, replace reverse check
spring; if shaft does not, check for scratches on the
inner surface of sleeve. If sleeve is in good order,
replace spring.
Select a suitable reverse accent shaft and reverse
check plate by referring to “Neutral Position Adjust-
ment.”

2) Installation of shifter arm
1and selector arm
8
Install shifter arm into the partition from the front while
inserting selector arm into the opening in reverse check
sleeve. Pass shaft through hole in selector arm until its end
comes out of the rear of transfer case.
NOTE:
Apply a coat of gear oil to shifter arm. Also make sure oil
seal is positioned properly.

1) Install transfer case
2with extension assembly
1.
2) Secure selector arm to shifter arm with shifter fork
screw

3. Shifter arm should be caught by pawl of rod.
Selector arm must be engaged with reverse check sleeve
assembly.
3) Adjustment of neutral position
(1) Shift gear into 3rd gear position.
(2) Shifter arm turns lightly toward the 1st/2nd gear
side but heavily toward the reverse gear side because
of the function of the return spring, until arm contacts
the stopper.
(3) Make adjustment so that the heavy stroke (reverse
side) is a little more than the light stroke (1st/2nd side).
(4) To adjust, remove bolts holding reverse check
sleeve assembly

4to the case, move sleeve assem-
bly outward, and place adjustment shim (0 to 1 ea.)
between sleeve assembly and case to adjust the clear-
ance.

When shim is removed, the neutral position will move
closer to reverse; when shim is added, the neutral position
will move closer to 1st gear.
If shims alone cannot adjust the clearance, replace
reverse accent shaft and re-adjust.

reverse check mechanism operates properly. Also check to
see if arm returns to neutral when released from the
reverse position. If arm does not return properly, replace
reverse check plate.
