CAUTION!
Do not force the shaft tube into the
powerhead! Excessive force can
damage the shaft tube and
mainshaft.
CAUTION!
Do not remove the D-shaped shim
washer! The shim washer pre-
vents damage from overtightening
the tube clamp screw.
2. Use the 4 mm hex wrench to
loosen the tube clamp screw. Verify
that the D-shaped shim washer is
positioned as shown. See Figure 6.
3. Add some moly-type EP grease to
splines at the end of the main shaft.
4. Slide the outer tube into the tube
clamp until the tube bottoms. If
installation is difficult, rotate the
outer tube or gearcase shaft
slightly until you feel the mainshaft
splines engage with the powerhead.
See Figure 5.
5. Position the outer tube so that the
ignition switch is facing up and the
throttle lever is facing down. See
Figure 5.
6. Slide the outer tube into the
powerhead until the throttle grip
just contacts the tube clamp.
7. Tighten the clamp screw firmly.
