Flywheel Magneto Removal

Remove the magneto cover (see Magneto Cover Re-
moval).
Hold the flywheel with the rotor holder [A], and remove
the flywheel nut [B].
Special Tool - Rotor Holder: 57001-1567
Screw the rotor puller [A] into the flywheel.
Remove the flywheel from the crankshaft by turning in the
puller center bolt and tapping the head of the bolt lightly
with a hammer, while holding the puller body steady.
There is the woodruff key in the crankshaft tapered por-
tion.
Special Tool - Rotor Puller M24 × 1.5: 57001-1565
Never strike the grab bar or the flywheel itself. Strik-
ing the bar can bend it. If the flywheel is struck, the
magnets may lose their magnetism.

Flywheel Magneto Installation

Using a high-flash point solvent, clean off any oil or dirt
that may be on the crankshaft taper [A] or in the hole [B]
of the flywheel. Dry them with a clean cloth.
Fit the woodruff key [C] in the slot in the crankshaft.
Confirm the flywheel fit or not to the crankshaft before
tightening it with specified torque.
Install the flywheel and tighten the flywheel nut with 45
N·m (4.5 kgf·m, 33 ft·lb) of torque.
Remove the flywheel nut.
Prepare the auxiliary bolt (M12 × P1.25 × L100 mm).
Check the tightening torque with rotor puller and auxiliary
bolt.
Special Tool - Rotor Puller M24 × 1.5: 57001-1565
If the flywheel is not pulled out with 20 N·m (2.0 kgf·m,
15 ft·lb) of drawing torque, it is installed correctly.
If the flywheel is pulled out with under 20 N·m (2.0 kgf·m,
15 ft·lb) of drawing torque, clean off any oil, dirt or flaw of
the crankshaft and flywheel tapered portion, and dry them
with a clean cloth. Then, confirm that it is not pulled out
with above torque.
