Required Tools    
Tool     Part Number     Part Description     Qty    
A (1)     9U-6198     Crankshaft Turning Tool     1    
A (2)     9U-7336     Housing     1    
5P-7305 Engine Turning Tool     1    
B     8S-2269     Ridge Reamer     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.Start By:
Remove the cylinder head. Refer to Disassembly and Assembly, "Cylinder Head" for the correct procedure.
Remove the piston cooling jets. Refer to Disassembly and Assembly, "Piston Cooling Jets" 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.
Use Tooling (A) to rotate the crankshaft until the crank pin is at the bottom center position.
Use Tooling (B) to remove the carbon ridge from the top inside surface of the cylinder bore.
