( 1 ) The Crankshaft Turning Tool is used on the front pulley.
( 2 ) This Tool is used in the aperture for the electric starting motor.Start By:
Remove the engine oil pump. Refer to Disassembly and Assembly, "Engine Oil Pump - Remove" for the correct procedure.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.
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" for the correct procedure.
Use Tooling (A) to rotate the crankshaft until the crank pin is at the bottom center position.If necessary, remove the glow plugs. Ref to Disassembly and Assembly, "Glow Plugs" for the correct procedure.Note: Removal of glow plug aids removal of the connecting rod bearing. It 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 (3) and connecting rod cap (2) in order 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 (1) and connecting rod cap (2) from connecting rod (3). Discard bolts (1) .
Remove lower bearing shell (4) from connecting rod cap (2). Keep the bearing shell and the connecting rod cap together.
Carefully push connecting rod (3) into the cylinder bore until connecting rod (3) is clear of the crankshaft. Remove upper bearing shell (5) from the connecting rod. Keep the bearing shells together.Note: Do not push on 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. Refer to Disassembly and Assembly, "Connecting Rod Bearings" for the correct procedure.Installation Procedure
