( 13 ) 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 bolts.
Inspect the pins of the crankshaft for damage. If the crankshaft is damaged, replace the crankshaft or recondition the crankshaft. Refer to Disassembly and Assembly, "Crankshaft - Remove" and Disassembly and Assembly, "Crankshaft - Install". Ensure that the connecting rod bearings are clean and free from wear or damage. If necessary, replace the connecting rod bearings.

Aligning the bearing in the center of the connecting rod
Clean the connecting rod (2) . Position Tooling (C) onto connecting rod (5) .
Install the upper half of connecting rod bearing (4) to connecting rod (5) . Ensure that the bearing is centralized in the connecting rod. Refer to Illustration 2. Remove Tooling (C) .The ends of the bearing must be centered in the connecting rod. The ends of the bearing must be equally positioned in relation to the faces of the connecting rod.
Clean the connecting rod cap (2) . Position Tooling (C) onto connecting rod cap (2) .
Install lower connecting rod bearing (3) to connecting rod cap (2) . Ensure that the connecting rod bearing is centralized in the connecting rod cap. Refer to Illustration 2. Remove Tooling (C) .The ends of the lower connecting rod bearing must be centered in the connecting rod cap. The ends of the lower connecting rod bearing must be equally positioned in relation to the faces of the connecting rod cap.
Lubricate upper connecting rod bearing (4) with clean engine oil.
If necessary, use Tooling (A) in order to rotate the crankshaft until the crankshaft pin 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.
Lubricate the pin of the crankshaft and lubricate lower connecting rod bearing (3) with clean engine oil.

Typical example
Install connecting rod cap (2) to connecting rod (5) .Note: Ensure that etched Number (X) on connecting rod cap (2) matches etched Number (X) on connecting rod (5) . Ensure the correct orientation of the connecting rod cap. The forged Marks (Y) on the connecting rod and the connecting rod cap should be on the same side. Refer to Illustration 1.
Install new bolts (1) . Tighten the bolts evenly to a torque of 18 N m (13 lb ft).Note: Do not reuse the
