REVERSE CHECK SLEEVE

E: INSPECTION

• 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.
• 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 re-
verse check plate. <Ref. to MT-58, ADJUSTMENT,
Reverse Check Sleeve.>

F: ADJUSTMENT

1. NEUTRAL POSITION ADJUSTMENT

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 be-
cause of the function of the return spring, until arm
contacts 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 bolts holding reverse check
sleeve assembly to the case, move sleeve assem-
bly outward, and place adjustment shim (0 to 1 ea.)
between sleeve assembly and case to adjust the
clearance.

NOTE:
• Be careful not to break O-ring when placing
shim(s).
• 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, re-
place reverse accent shaft and re-adjust.

2. REVERSE CHECK PLATE ADJUST-
MENT

1) Shift shifter arm to “5th” and then to reverse to
see if reverse check mechanism operates properly.
2) 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.
