Reverse Check Sleeve
C: DISASSEMBLY
1) Cover the reverse check sleeve with a rag, and
remove the snap ring using a screwdriver.
NOTE:
Replace the snap ring with a new one if deformed
or reactive force is weakened.
2) Remove the reverse check plate, reverse check
spring, reverse check cam, return spring (5th-Rev),
reverse accent shaft, return spring cap and return
spring (1st-2nd).
3) Remove the O-ring.
NOTE:
Reverse check sleeve assembly uses an O-ring
which should not be scratched.
Be careful not to break the adjustment shim
placed between reverse check sleeve assembly
and case.
D: ASSEMBLY
1) Install the return spring (1st-2nd), return spring
cap, reverse accent shaft, check cam, return spring
and check spring onto reverse check sleeve.
NOTE:
Be sure the bent section of reverse check spring is
positioned in the groove in check cam.
2) Hook the bent section of reverse check spring
over reverse check plate.
3) Rotate the cam so that the protrusion of reverse
check cam is at the opening in plate.
4) With the cam held in that position, install the
plate onto reverse check sleeve and hold with snap
ring.
5) Position a new O-ring in groove in sleeve.

MANUAL TRANSMISSION AND DIFFERENTIAL
Reverse Check Sleeve
E: INSPECTION
Make sure the cutout section of reverse accent
shaft is aligned with the opening in reverse check
sleeve.
Spin the cam by hand for smooth rotation.
Move the cam and shaft all the way toward plate
and release.
If the cam does not return properly, replace the re-
verse check spring; if shaft does not, check for
scratches on the inner surface of sleeve. If sleeve
is in good order, replace the spring.
Select a suitable reverse accent shaft and re-
verse check plate.
F: ADJUSTMENT
1. NEUTRAL POSITION ADJUSTMENT
1) Shift the gear into 3rd gear position.
2) Shifter arm turns lightly toward the 1st/2nd gear
side but heavily toward the reverse gear side be-
cause of the function of return spring, until arm con-
tacts the stopper.
3) Make adjustment so that the heavy stroke (re-
verse side) is a little more than the light stroke (1st/
2nd side).
4) To adjust, remove the bolts holding reverse
check sleeve assembly to the case, move the
sleeve assembly outward, and place adjusting
shim (0 to 1 ea.) between sleeve assembly and
case to adjust the clearance.5) Be careful not to break the O-ring when placing
shim(s).
NOTE:
When the 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 the shims alone cannot adjust clearance, re-
place the reverse accent shaft and re-adjust.
2. REVERSE CHECK PLATE ADJUST-
MENT
1) Shift the shifter arm to “5th” and then to reverse
to see if reverse check mechanism operates prop-
erly.
2) Also check to see if the arm returns to neutral
when released from reverse position. If the arm
does not return properly, replace the reverse check
plate.

9) Place the transmission with case left side facing
downward and put ST1 on bearing outer race.
10) Screw the retainer assembly into left case from
the bottom with ST2 Fit the ST3 on transmission
main shaft. Shift the gear into 4th or 5th and turn
the shaft several times. Screw in the retainer while
turning ST3 until a slight resistance is felt on ST2.
This is the contact point of hypoid gear and drive
pinion shaft. Repeat the above sequence several
times to ensure the contact point.

ST3 499927100 HANDLE11) Remove the weight and screw in the retainer
without O-ring on upper side and stop at the point
where slight resistance is felt.
NOTE:
At this point, the backlash between hypoid gear
and drive pinion shaft is zero.

12) Fit the lock plate. Loosen the retainer on the
lower side by 1-1/2 notches of lock plate and turn in
the retainer on upper side by the same amount in
order to obtain the backlash.
NOTE:
The notch on the lock plate moves by 1/2 notch if
the plate is turned upside down.
13) Turn in the retainer on the upper side addition-
ally by 1 notch in order to apply preload on taper
roller bearing.
14) Tighten temporarily both the upper and lower
lock plates and mark both holder and lock plate for
later readjustment.
15) Turn the transmission main shaft several times
while tapping around the retainer lightly with plastic
hammer.
16) Inspect and adjust the backlash and tooth con-
tact of hypoid gear.
