3. If the engine has a plastic grass screen, snap the
screen onto the fan. See Figure 11-27. Due to the
possibility of damaging the posts during removal,
install the retainers on different posts from which
they were removed. Start the retainers by hand,
then push them down with a 13 mm (1/2”) socket
until they lock. If the engine has a metal screen, it
will be installed later.
NOTE: Make sure the flywheel key is installed
properly in the keyway. The flywheel
can become cracked or damaged if the
key is not properly installed.
2. Install the flywheel onto the crankshaft being
careful not to shift the woodruff key. See Figure
11-24.
3. Install the hex flange screw and washer.
4. Use a flywheel strap wrench or holding tool to

securing the flywheel to the crankshaft to
66.4 N·m (49 ft. lb.). See Figure 11-25.
