8. Lubricate bushing (8) for piston pin (6) in the
connecting rod with clean engine oil. Lubricate the
bore for the piston pin in piston (4) with clean
engine oil.
9. Install piston pin (6) to piston (4).
Note: If the piston pin cannot be installed by hand,
heat the piston to a temperature of 45° ± 5°C
(113° ± 9°F).
10. Use Tooling (A) in order to install circlips (5) to the
piston pin bore in piston (4).
Note: Ensure that the circlips are seated in the
grooves in the piston.
11. Install upper bearing shell (9) into connecting rod
(7). Ensure that the locating tab for the upper
bearing shell is correctly seated in slot in the
connecting rod.
12. Install lower bearing shell (10) into connecting rod
cap (11). Ensure that the locating tab for the lower
bearing shell is correctly seated in the slot in the
connecting rod cap.
13. Temporarily install connecting rod cap (11) and
bolts (12) to connecting rod (7) when the assembly
is out of the engine. Ensure that the etched
number on connecting rod cap matches the
etched number on connecting rod. Ensure the
correct orientation of the connecting rod cap. The
locating tab for the upper bearing shell and the
lower bearing shell should be on the same side.
Tighten bolts (12) to a torque of 20 N·m (177 lb in)
.
14. Repeat Step 1 through Step 13 for the remaining
piston and connecting rod assemblies.
Note: Fracture split connecting rods should not be
left without the connecting rod caps installed.
End By:
a. Install the pistons and the connecting rods.
Refer to Disassembly and Assembly, “Piston
and Connecting Rods - Install” for the correct

NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
1. If the connecting rod caps were temporarily
installed, remove the connecting rod caps. If
necessary, thoroughly clean all of the components.
Note: Discard all used connecting rod bolts.
2. Apply clean engine oil to the cylinder bore, piston,
piston rings, connecting rod shell, and the shell in
the connecting rod cap.
3. Rotate crankshaft until the required crankshaft
journal is at bottom center position. Lubricate the
crankshaft journal with clean engine oil.
