ENGINE

3. Watch the gap along the crankcase mating surface and

separate the crankcase evenly.

CRANKSHAFT / CAM & OIL CHAIN /

SPROCKET INSPECTION

1. Inspect the crankshaft main bearings and cam and oil

pump chain sprocket for wear or damage.

4. Once the crankshaft bearing is free from the case,

the crankshaft and cam chain can be removed by

hand for service.

CRANKSHAFT REMOVAL

1. Remove right hand crankcase with soft faced hammer.

2. Press the crankshaft out. Use care not to damage the

crankshaft oil passage on the right end crankshaft end.

NOTE: Use care not to damage the crankshaft end.

NOTE: Due to extremely close tolerances and

minimal wear, the bearings must be inspected

visually, and by feel. Look for signs of discoloration,

scoring or galling. Turn the outer race of each

bearing.

The bearings should turn smoothly and quietly. The inner

race of each bearing should fit tightly in the crankshaft.

The outer race should be firm with minimal side to side

movement and no detectable up and down movement.

2. Replace the crankshaft if the components fail visual

inspection.
