ELECTRICAL SYSTEM
NOTE
The flywheel can be removed with the
engine installed. The accompanying
photographs show the engine removed
for clarity.
2. Hold the starter pulley and loosen the fly-
wheel retaining nut (Figure 10, typical). Threads
of the nut may be fixed with Loctite.
3. Unbolt and remove the starter pulley (Figure
19) from the flywheel.

CAUTION
Protect the crankshaft from damage
while using the puller in Step 4. A pro-
tective cap can be made by welding a
small plate to the end of a stock flywheel
nut.

4. Attach the flywheel puller (part No. 0144-
31 0) available from Arctco, or equivalent (Fig-
ure 18, typical).
CAUTION
On models so equipped, be careful not to
damage the sensors (Figure 20 or Fig-
ure 21) located outside the flywheel
when removing the flywheel. The safer
procedure is to remove the sensors be-
fore removing the flywheel.
CAUTION
Do not heat the flywheel or pound on the
flywheel while attempting to remove it.
Heat can cause the flywheel to seize onto
the crankshaft. Hitting the flywheel can
damage the flywheel, crankshaft or
crankshaft bearings.
5. Tighten the puller screw until the flywheel
breaks free of the crankshaft taper. It may be
necessary to tap the center screw of the puller
sharply with a hammer to jar the flywheel loose.
Do not hit the flywheel.
6. Remove the flywheel and the puller assembly,
then remove the puller from the flywheel.
7. Remove the Woodruff key (Figure 14, typi-
cal) from the crankshaft.
8. Clean the tapered surfaces of the flywheel and
crankshaft. The surfaces must be dry and clean
when installing the flywheel.
CAUTION
Check the condition of the keyway in the
flywheel (Figure 22) and in the crank-
shaft (Figure 14). Some cleanup is pos-
sible, but extreme damage cannot be
repaired and should be serviced by in-
stalling new parts.
