Required Tools
Tool Part Number Part Description Qty
A(1) 9U-6198 Crankshaft Turning Tool 1
A(2) 5P-7306 Housing 1
5P-7305 Engine Turning Tool 1
B 227-4390 E12 Torx Socket 1
C 8T-3052 Degree Wheel 1
(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. Note: If the bearing shells are replaced, check whether oversize bearing shells were previously installed.

Install upper bearing shell (4) into connecting rod (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.
Lubricate upper bearing shell (4) with clean engine oil.
Use Tooling (A) to rotate the crankshaft until the crankshaft pins is at the bottom dead center position.
Carefully pull connecting rod (5) 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 (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.
Lubricate the pin of the crankshaft and lubricate lower bearing shell (3) with clean engine oil.

Dot punched number in Position (X)
Install connecting rod cap (2) to connecting rod (5). Note: Ensure that dot punched number in Position (X) on connecting rod cap (2) matches dot punched number in Position (X) on connecting rod (5). 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.Note: Do not reuse the old bolts in order to secure the connecting rod cap.
Use Tooling (B) in order to install new bolts (1) to the connecting rod. 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 in order to ensure that there is no binding.
Repeat Step 2 through Step 11 in order to install the remaining connecting rod bearings. Note: If all connecting rod bearings require replacement, the procedure can be carried
