Disassembly and assembly

4. Remove lower bearing shell (3) from connecting
rod cap (2). Keep the bearing shell and the
connecting rod cap together.
5. Carefully push connecting rod (5) into the cylinder
bore until connecting rod (5) is clear of the
crankshaft. Remove upper bearing shell (4) from
the connecting rod. Keep the bearing shells
together.
Note: Do not push the fracture split surfaces of the
connecting rod as damage may result. Do not allow
the connecting rod to contact the piston cooling jet.
6. Repeat Step 1 through Step 5 in order to remove
the remaining bearing shells.
Note: Fracture split connecting rods should not be
left without the connecting rod caps installed. After
the removal procedure for the bearing shells is
complete, carry out the installation procedure as
soon as possible. Refer to Disassembly and
Assembly, “Connecting Rod Bearings - Install” for the

(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.
4. Lubricate upper bearing shell (4) with clean engine
oil.
5. Carefully guide 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 lower bearing
shell (3) into 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.
