(1) The Crankshaft Turning Tool is used on the front pulley.
(2) This Tool is used in the aperture for the electric starting motor.Note: Either Tooling (A) can be used. Use the Tooling that is most suitable.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Discard all used Connecting Rod fasteners.
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" for the correct procedure. Ensure that the bearing shells are clean and free from wear and damage. If necessary, replace the bearing shells.
Illustration 1 g06362599
Install upper bearing shell (5) into connecting rod (3).Note: If the bearing shells are being reused, the bearing shells must be installed in the original location and orientation.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.
Use Tooling (A) to rotate the crankshaft until the crankshaft pin is at the bottom dead center position.
Carefully pull connecting rod (3) 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).
Lubricate the pin of the crankshaft and lubricate lower bearing shell (4) with clean engine oil.
Illustration 2 g06360869
Install connecting rod cap (2) to connecting rod (3).Note: Ensure that etched Number (Y) on connecting rod cap (2) matches etched Number (Y) on connecting rod (3). Ensure the correct orientation of the connecting rod cap.Note: Do not reuse the old connecting rod bolts to secure the connecting rod cap.
Install new bolts (1) to the connecting rod. Use Tooling (B) tighten the bolts evenly to a torque of 40 N m (30 lb ft).
Turn the bolts through an additional 120 degrees in a clockwise direction. Use Tooling (B) and Tooling (C) to achieve the correct final torque.
Ensure that the installed connecting rod assembly has tactile side play. Rotate the crankshaft to ensure that there is no binding.
Repeat Step 2 through Step 11 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 4 and 2 with 3. 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" for the correct procedure.
If the glow plugs were removed, install the glow plugs. Ref to Disassembly and Assembly, "Glow Plugs - Remove and Install" for the correct procedure.End By:
Install the engine oil pan. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install" for the correct procedure.
