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 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:
^ For reverse check sleeve assembly, use an O-ring which should not be scratched.
^ Be careful not to break the adjusting shim placed between reverse check sleeve assembly and case.

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 the O-ring in groove in sleeve.

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 reverse 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 reverse check plate.

ADJUSTMENT

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 because of the function of 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 the bolts holding reverse check sleeve assembly to the case, move the sleeve assembly outward, and place adjusting shim 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, replace the reverse accent shaft and re-adjust.








REVERSE CHECK PLATE ADJUSTMENT
1) Shift the shifter arm to "5th" and then to reverse to see if reverse check mechanism operates properly.
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.
