SHIFT CONTROL
lInstall shift knob according to the following.
–Apply cement to threads of control lever assembly.
–Tightening shift knob until reacting. Then align shift knob to the
position as shown in the figure within one turn.
CAUTION:
Do not adjust shift knob with loosing.
CAUTION:
lInsert bushing of control lever assembly to the hole of striking arm as far as bushing goes.
lApply multi-purpose grease to socket and bushing.
lBe careful with the orientation guide plate and boot.
lTighten guide plate mounting bolts to the specified torque.
lBe careful with the orientation clip.
lDo not reuse clip.
lBe careful with the orientation control lever boot and insu-
lator.
INSPECTION AFTER INSTALLATION
After installing, confirm the following items:
lWhen control lever assembly is shifted to each position, make sure there is no binding or disconnection in
each boot.
lWhen shifted to each position, make sure there is no noise, catching, and backlash. Especially when con-
trol lever assembly is shifted to 5th, 6th without pressing downward, check for catching.
lWhen control lever assembly is shifted to 1st, 2nd side and 5th, 6th side, confirm control lever assembly
returns to neutral position smoothly.
lIn any position other than reverse, confirm that control lever assembly can be pressed downward.
lWith control lever assembly pressed downward, confirm that it can be shifted to reverse.
lWhen shifted from reverse to neutral position, confirm control lever assembly returns to neutral position
smoothly with spring power.
lWithout control lever assembly pressed downward, confirm that it cannot be shifted to reverse.
