Typical example
1. Before installation of the crankshaft front seal
and the wear sleeve, inspect the crankshaft for
scratches. Also, inspect the crankshaft for any
distortion on the surface that may lead to an out of
round condition. Use a polishing cloth in order to
remove any imperfections on the crankshaft.
1. Use a 4 mm (0.158 inch) drill in order to make
three or more holes in wear sleeve (2).
2. Use Tooling (A) to remove the wear sleeve.
3. Use a 4 mm (0.158 inch) drill in order to make

to the back of first Tooling (C). Align camshaft (8)
with the bore of Tooling (B). Tighten the bolts that
hold Tooling (B) to front housing (7).
5. Install Tooling (B) on front housing (7). Tooling (B)
is used to support camshaft (8). Do not tighten the
bolts for Tooling (B) at this time.
Note: Tooling (C) will support the rear of the camshaft
as the camshaft is moved out of the cylinder head
and into Tooling (B).
8. Use Tooling (D) to move camshaft (8) toward the
front of the engine. Reposition Tooling (D), as
required.
Note: Avoid lifting the camshaft with Tooling (D). The
camshaft should rest on Tooling (A). Lifting of the
camshaft can cause misalignment as the camshaft
is removed, resulting in damage to the camshaft
bearings.

9. Carefully slide the camshaft to the front of the
engine for removal. Use two people to remove
the camshaft. Keep the camshaft level while the
camshaft is being removed from the cylinder
head. The weight of camshaft (8) is approximately
39 kg (86 lb).
6. Remove Torx screws (9) and cover (10). Remove
the O-ring seal from the cover.
Note: Rotate the camshaft during removal. This will
prevent the camshaft from binding in the camshaft
bearings.

1. Use Tooling (A) to rotate the crankshaft until the
piston is at the bottom center.
Start By:
2. Remove the carbon ridge from the top inside
surface of the cylinder liner.
a. Remove the pistons and connecting rods. Refer
to Disassembly and Assembly, “Pistons and
Connecting Rods - Remove”.
3. Inspect the connecting rod and connecting rod cap
for the proper identification mark. The connecting
rod and the connecting rod cap should have an
etched number on the side. The number should
match the cylinder number. Mark the connecting
rod and the connecting rod cap, if necessary.
Note: Mark the components of each piston and
connecting rod assembly. The components must be
reinstalled in the original location. Do not interchange
components.
Note: Do not stamp the connecting rod assembly.
Stamping or punching the connecting rod assembly
could cause the connecting rod to fracture.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
4. Remove bolts (1) and connecting rod bearing cap
(2). Push the connecting rod until the piston rings
are out of the cylinder liner.
