Removal Procedure
Start By:
Remove the engine oil suction pipe. Refer to Disassembly and Assembly, "Engine Oil Pan - Remove and Install" for the correct procedure.
If necessary, remove the balancer. Refer to Disassembly and Assembly, "Balancer - Remove " for the correct procedure
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 and 4 then 2 and 3. Ensure that the installation procedure on one pair connecting rods is completed before starting the removal procedure on the next pair of connecting rods.

(X) Identification marks
Illustration 2 g01341322
The connecting rod and the connecting rod cap should have an etched number in Positions (X). The number on the connecting rod and the connecting rod cap must match. If necessary, make a temporary mark on connecting rod (5) 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.
Rotate the crankshaft so that required connecting rods are at bottom center position. Remove bolts (1) and discard the bolts.
Remove connecting rod cap (2) from connecting rod (5).
Remove lower bearing shell (3) from connecting rod cap (2). Keep the bearing shell and the connecting rod cap together.
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.
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 correct procedure.
