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.<Ref. to 5MT-65, ADJUST-
MENT, Reverse Check Sleeve.>
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 adjustment
shim (0 to 1 ea.) between sleeve assembly and
case to adjust the clearance.
CAUTION:
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.
