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.

3. TOOTH CONTACT OF HYPOID GEAR
Check the tooth contact of hypoid gear as follows:
Apply a uniform thin coat of red lead on both tooth
surfaces of 3 or 4 teeth of the hypoid gear. Move
the hypoid gear back and forth by turning the trans-
mission main shaft until a definite contact pattern is
developed on hypoid gear, and judge whether face
contact is correct. If it is inaccurate, make adjust-
ment.
Tooth contact is correct.

side. Inspect the clearance between reverse idler
gear and transmission case wall.
If out of specification, select the appropriate re-
verse shifter lever and adjust.
Clearance A:
6.0 — 7.5 mm (0.236 — 0.295 in)
2) After installing a suitable reverse shifter lever,
shift into neutral. Inspect the clearance between re-
verse idler gear and transmission case wall.
If out of specification, select the appropriate washer
and adjust.

0 — 0.5 mm (0 — 0.020 in)
3) Check the reverse idler gear and shaft for dam-
age. Replace if damaged.
D: ADJUSTMENT
1) Select the appropriate reverse shifter lever from
the table below, and adjust until the gap between
the reverse idler gear and transmission case wall is
within specification.
Clearance A:
6.0 — 7.5 mm (0.236 — 0.295 in)
2) Select the appropriate washer from the table be-
low, and adjust until the gap between the reverse
