Crankshaft and Camshaft Components
• When honing is completed, wash the cylinder
block with hot water and soap. The cylinder wall
is adequately cleaned when a white rag wiped
in cylinder comes out clean. Use brushes to
clean all passages and crevices. Rinse with hot
water and dry with compressed air. Apply clean
engine oil to all steel surfaces to prevent
rusting.
Reassembly of Crankshaft and
Piston Components
Notes:
• Proceed slowly. Make no forced assemblies
unless a pressing operation is called for. All
parts must be perfectly clean and lightly
lubricated when assembled.
• Use new gaskets, seals and O-rings during
assembly.
• Liberally apply clean engine oil to all internal
parts during assembly.
• All fasteners should be tightened to a given
torque. If a special torque is not provided in the
Special Torque Chart on page 6-25, tighten to
standard torque specifications. See Tightening
Torques for Standard Bolts and Nuts on
page 4-46.
Reassembly of Pistons
1. Select the parts needed to reassemble the
piston and connecting rod for one cylinder.
2. If removed, install a new wrist pin bushing
(Figure 6-130, (7)) using a press and the
appropriate service tool. Be sure to align the oil
holes.

3. Reinstall one circlip (Figure 6-130, (5)) into the
piston. Ensure the circlip is securely seated in
the groove.
IMPORTANT
The piston and connecting rod must be
assembled together in the correct
orientation. The orientation of the piston
and connecting rod are different depending
on engine model.
