2) Secure selector arm to shifter arm with shifter fork
screw

3. Shifter arm should be caught by pawl of rod.
Selector arm must be engaged with reverse check sleeve
assembly.
3) Adjustment of neutral position
(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 because
of the function of the 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 bolts holding reverse check
sleeve assembly

4to the case, move sleeve assem-
bly outward, and place adjustment shim (0 to 1 ea.)
between sleeve assembly and case to adjust the clear-
ance.
