Note:
Install the bearing shells for the connecting
rods dry when clearance checks are performed. Refer
to Disassembly and Assembly, “Bearing Clearance -
Check”. Apply clean engine oil to the bearing shells
for the connecting rods during
fi
nal assembly.
Note:
Ensure that the piston and the connecting rod
assembly is installed in the correct cylinder.
3.
Use Tooling (A) to rotate the crankshaft until the
crankshaft pin is at the bottom center position.
Lubricate the crankshaft pin with clean engine oil.

4.
Install Tooling (B) onto piston (4).
Note:
Ensure that Tooling (B) is installed correctly
and that piston (4) can easily slide from the tool.
Note:
The arrow on the top of the piston must be
toward the front of the engine. The locating tab for
the bearing shell of the connecting rod must be on
the same side of the engine as the piston cooling jet.
5.
Carefully push the piston and the connecting rod
assembly into the cylinder bore and onto the
crankshaft pin.
Note:
Do not damage the
fi
nished surface of the
crankshaft pin.

6.
Install connecting rod cap (2) onto connecting rod
(1).
Note:
Ensure that etched number (X) on connecting
rod cap (2) matches etched number (X) on connecting
rod (1). Ensure the correct orientation of connecting
rod cap (2). The locating tab for the upper bearing
shell and the lower bearing shell should be on the
same side.
7.
Install new bolts (3) to connecting rod (1). Tighten
the bolts evenly to a torque of 18 N·m (13 lb ft).
Note:
Do not reuse the old bolts in order to secure
the connecting rod cap.
8.
Tighten the bolts evenly to a torque of 70 N·m
(52 lb ft).
9.
Turn the bolts for an additional 120 degrees. Use
Tooling (C) to achieve the correct
fi
nal torque.
10.
Ensure that the installed connecting rod assembly
has tactile side play. Rotate the crankshaft in order
to ensure that there is no binding.
11.
Repeat Steps 2 through 10 in order to install the
remaining pistons and connecting rods.
12.
Check the height of the pistons above the top face
of the cylinder block. Refer to System Operation,
Testing and Adjusting, “Piston Height - Inspect” for
the correct procedure.

Install the piston cooling jets. Refer to Disassembly
and Assembly, “Piston Cooling Jets - Remove
and Install”.
