Cylinder Head Removal
Remove thermostat cover and thermostat assem-
bly. Refer to THERMOSTAT SERVICING on
p. 186.
Loosen in stages and remove cylinder head
screws. Remove the cylinder head. Discard ther-
mostat seal and O-rings.
Connecting Rods and Pistons
Use a permanent marker to identify each connect-
ing rod cap, connecting rod, and piston by cylinder
number. Number 1 is closest to the top.
Use Torquing Socket, P/N 331638, to loosen in
stages the rod cap retaining screws. DO NOT
remove the screws.
Use one hand to support the piston, and remove
the rod cap screws with your other hand. Remove
each piston and rod assembly.
Reattach each rod cap to its rod as
soon as the piston is removed. Each cap is
unique and can only be installed on its mated
rod. Do not allow rod to contact inside surface
of cylinder or crankshaft.
IMPORTANT: Identify all internal components
so that if reused, they can be reinstalled in their
original positions.
Repeat steps for each remaining piston and con-
necting rod.
