Remove the engine oil pump.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Discard all used Connecting Rod fasteners.
Note: If all connecting rod bearings require replacement, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 6, 2 with 5 and 3 with 4. Ensure that both pairs of the connecting rod bearings are installed before changing from one pair of cylinders to another pair of cylinders. Refer to Disassembly and Assembly, "Connecting Rod Bearings - Install".
Rotate the crankshaft until the crank pin is at the bottom center position. If necessary, remove the glow plugs. Refer to Disassembly and Assembly, "Glow Plugs - Remove and Install".Note: Removal of glow plug aids removal of the connecting rod bearing. Glow plug removal is not essential.

The connecting rod and the connecting rod cap should have an etched Number (X) on the side. The number on the connecting rod and the connecting rod cap must match. If necessary, make a temporary mark on connecting rod (1) and connecting rod cap (2) to identify the cylinder number. Note: Do not punch identification marks onto fracture split connecting rods. Do not stamp identification marks onto fracture split connecting rods.
Remove bolts (3) and connecting rod cap (2) from connecting rod (1). Discard the bolts.
Remove lower bearing shell (4) from connecting rod cap (2). Keep the bearing shell and the connecting rod cap together.
Carefully push connecting rod (1) into the cylinder bore until connecting rod (1) is clear of the crankshaft. Remove upper bearing shell (5) from the connecting rod. Keep the bearing shells together. Note: Do not push against the fracture split surfaces of the connecting rod as damage may result. Do not allow the connecting rod to contact the piston cooling jet.
Repeat Step 1 through Step 5 for 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.Installation Procedure
Inspect the pins of the crankshaft for damage. If the crankshaft is damaged, replace the crankshaft. Refer to Disassembly and Assembly, "Crankshaft - Remove" and Disassembly and Assembly, "Crankshaft - Install". Ensure that the bearing shells are clean and free from wear or damage. If necessary, replace the bearing shells.

Install the upper bearing shell (5) into connecting rod (1). 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.
Lubricate upper bearing shell (5) with clean engine oil.
Rotate the crankshaft until the crankshaft pin is at the bottom dead center position.
Carefully pull connecting rod (1) against the crankshaft pin. Note: Do not allow the connecting rod to contact the piston cooling jet.
Clean connecting rod cap (2). Install lower bearing shell (4) 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. 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.
Lubricate the pin of the crankshaft and lubricate lower bearing shell (4) with clean engine oil.
Install connecting rod cap (2) to 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 the connecting rod cap. The locating tab for the upper bearing shell and the lower bearing shell should be on the same side.
Install new bolts (3) to the connecting rod. Tighten the bolts evenly to a torque of 18 N m (13 lb ft). Note: Do not reuse the old bolts to secure the connecting rod cap.
Tighten the bolts evenly to a torque of 70 N m (52 lb ft).
Turn the bolts through an additional 120 degrees. Use Tooling (B) to achieve the correct final torque.
Ensure that the installed connecting rod assembly has tactile side play. Rotate the crankshaft in order to ensure that there is no binding.
Repeat Step 2 through Step 12 for the remaining connecting rod bearings. Note: If all connecting rod bearings require replacement, the procedure can be carried out on two cylinders at the same time. The procedure can be carried out on the following pairs of cylinders. 1 with 6, 2 with 5 and 3 with 4. Ensure that both pairs of the connecting rod bearings are installed before changing from one pair of cylinders to another pair of cylinders. Refer to Disassembly and Assembly, "Connecting Rod Bearings - Install".End By:
