Reassembly
Install Flywheel
Damaging Crankshaft and Flywheel can
cause personal injury.
Using improper procedures can lead to broken
fragments. Broken fragments could be thrown from
engine. Always observe and use precautions and
procedures when installing fl ywheel.
NOTE: Before installing fl ywheel make sure crankshaft
taper and fl ywheel hub are clean, dry, and
completely free of any lubricants. Presence of
lubricants can cause fl ywheel to be over
stressed and damaged when screw is torqued to
specifi cations.
NOTE: Make sure fl ywheel key is installed properly in
keyway. Flywheel can become cracked or
damaged if key is not properly installed.
NOTE: High output charging system fl ywheel (identifi ed
by 4 large cooling holes) has very strong
magnets. Magnet assembly guard on interior of
this fl ywheel has a thin, sharp edge. Wear
protective gloves when handling this fl ywheel.
1. Install woodruff key into crankshaft keyway. Make
sure key is properly seated and parallel with shaft
taper.
2. Set fl ywheel/fan assembly onto crankshaft, being
careful not to shift woodruff key. ETB ECV EFI
engines with high output charging system have a
fl ywheel with very strong magnets. Wear protective
gloves and use a fl ywheel puller to help line up
fl ywheel and crankshaft before magnets pull fl ywheel
into place.
3. Install screw and washer.
4. Use a fl ywheel strap wrench or holding tool to hold
fl ywheel. Torque screw to 69.8 N·m (51 ft. lb.).
Install Fan (Style B)
NOTE: Position locating tabs on back of fan into locating
holes of fl ywheel.
1. Install fan onto fl ywheel using screws (engines with
plastic grass screen). Engines with a metal grass
screen will leave fan loosely assembled.
2. Torque screws to 9.9 N·m (88 in. lb.).

gap must be set when installing. Later design
brackets require no adjustment.
1. Install crankshaft position sensor and bracket
assembly to crankcase posts.
2. On engines with earlier design bracket, snug screws
and check air gap of sensor with a feeler gauge. It
must be 0.20-0.70 mm (0.008-0.027 in.). Torque
bracket screws to 9.7 N·m (86 in. lb.).
On engines with later design bracket, secure bracket
assembly to crankcase posts. Torque bracket screws
to 7.3 N·m (65 in. lb.).
3. Push electrical connector on crankshaft position
