Disassembly

NOTE: These engines use valve stem seals on the
intake valves. Use a new seal whenever the
valve is removed or if the seal is deteriorated
or damaged in any way. Never reuse an old
seal.
4. Repeat the above procedure for the other cylinder
head. Do not interchange parts from one cylinder
head to the other.
Remove Grass Screen and Fan
1. On engines with a flat plastic screen, small metal
retainers are typically attached on three of the
seven mounting posts for positive retention of the
plastic grass screen. Use a hook-end tool next to
the post and pull outward to separate each of the
small metal retainers. Then unsnap the screen
from the mounting posts. See Figure 9-43.

Remove Flywheel
1. Use a flywheel strap wrench or holding tool (see
Section 2) to hold the flywheel and loosen the
hex. flange screw securing the flywheel to the
crankshaft. See Figure 9-45.
NOTE: Always use a flywheel strap wrench or
holding tool to hold the flywheel when
loosening or tightening the flywheel
screw.
Do not
use any type of bar or
wedge to hold the flywheel. Use of such
tools could cause the flywheel to become
cracked or damaged.
