🔌 Function

The housing supports and locates the upper crankshaft bearing.

It keeps the crankshaft correctly aligned within the cylinder block and provides the machined bores and sealing surfaces required by the upper bearing and oil seal.

Common signs of wear or damage:

• Corrosion in the bearing bore

• Bearing fit is loose

• Cracks around the mounting holes

• Damaged locating surfaces

• Oil-seal bore is scored

• Crankshaft has excessive movement

• Upper bearing noise

• Evidence of overheating or bearing rotation

• Damaged threads

• Crankcase pressure or oil leakage around the upper seal

Recommended checks before installation:

• Confirm both Yamaha part numbers

• Inspect the bearing bore for fretting and corrosion

• Measure bearing fit and housing dimensions

• Check the oil-seal and O-ring grooves

• Inspect all mounting holes and threads

• Replace the bearing, seals and O-rings where required

• Inspect the crankshaft journal

• Use the correct tightening sequence and sealant

• Confirm free crankshaft rotation after assembly
