1. Inspect the pins of the crankshaft for damage. If
the crankshaft is damaged, replace the crankshaft.
Refer to Disassembly and Assembly Manual,
"Crankshaft - Remove" and Disassembly and
Assembly Manual, "Crankshaft - Install". Ensure
that the bearing shells are clean and free from
wear or damage. If necessary, replace the bearing
shells.

2. Install the upper bearing shell (4) into the
connecting rod (5). Ensure that the locating tab for
the upper bearing shell is correctly seated in the
slot in the connecting rod.
Note: The ends of the upper bearing shell must be
centered in the connecting rod. The ends of the upper
bearing shell must be equally positioned in relation to
the mating faces of the connecting rod.
3. Lubricate the upper bearing shell (4) with clean
engine oil.
4. Use Tooling (A) to rotate the crankshaft until
the crankshaft pin is at the bottom dead center
position.
5. Carefully pull the connecting rod (5) against the
crankshaft pin.
Note: Do not allow the connecting rod to contact the
piston cooling jet.
6. Clean connecting rod cap (2). Install the lower
bearing shell (3) into the connecting rod cap
(2). Ensure that the locating tab for the lower
bearing shell is correctly seated in the slot in the
connecting rod cap.
Note: The ends of the lower bearing shell must be
centered in the connecting rod cap. The ends of the
lower bearing shell must be equally positioned in
relation to the mating faces of the connecting rod cap.
7. Lubricate the pin of the crankshaft and lubricate
the lower bearing shell (3) with clean engine oil.

8. Install the connecting rod cap (2) to the connecting
rod (5).
Note: Ensure that the etched number (X) on
connecting rod cap (2) matches the etched number
(X) on connecting rod (5). 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.
9. Install two new setscrews (1) to the connecting
rod. Tighten the setscrews evenly to a torque of
18 N·m (13 lb ft).
Note: Do not reuse the old setscrews in order to
secure the connecting rod cap.
10. Tighten the setscrews evenly to a torque of
70 N·m (52 lb ft).
11. Turn the setscrews through an additional 120
degrees. Use Tooling (B) to achieve the correct
final torque.
12. Ensure that the installed connecting rod assembly
has tactile side play. Rotate the crankshaft in order
to ensure that there is no binding.
13. Repeat Steps 2 through 12 for the remaining
connecting rod bearings.
End By:
a. Install the engine oil pump. Refer to Disassembly
and Assembly Manual, "Engine Oil Pump - Install".
