Replacing the 2-Speed Gears
First (Low) Gear:
After removing the outer gear cover remove the large circlip at the
outer face of the gear. Remove and replace the gear being sure to
insert the molded pins on the back of the gear with the holes in the
aluminum hub. Replace the circlip. Note: Special pliers are made that
make removal and installation of the circlip easier.
Replacing the Clutch Bell
Use a 3/32” wrench (provided) to remove the
retaining screw (turn counterclockwise) while
firmly holding the flywheel with a pair of pliers.
Remove the screw, washers and clutch bell,
being careful not to lose any shims that may
be used. Remove the ball bearings and brush
any loose dirt away from the bearing faces. Put
only ONE drop of oil on the inside face (the side
facing away from the clutch shoes) near the
inner race of the bearing. Install the bearings
into the new clutch bell. Before replacing the
clutch bell, wipe out the inside with motor
spray, lacquer thinner, or a similar cleaner (do
not use fuel or oil-based solvents). Replace
the clutch bell and secure with the retaining
screw in the same manner used to remove it.
Note: do not over-tighten the screw, as it is not
necessary.
Second (High) Gear:
Remove the nut and the thrust washer assembly from
the slipper. Slide both gears off of the shaft being
careful to leave the slipper pads in the steel slipper
cage. The 2-speed clutch shoes will be inside the
bell for the high gear. Use a 1/16-inch hex wrench to
remove the three button head screws and replace
the gear. Reinstall the high gear with the clutch shoes
in the bell, the large washer, low gear assembly and
thrust washer assembly as seen in the exploded view.
Adjust per the “Adjusting the Slipper” instructions and
replace the gear cover.
