🔌 Function

Provides the replaceable bearing shells the crankshaft main journals run in, carrying the crank in the block on a pressure-fed oil film.

⚠️ Common Signs of Failure

• Deep rumble from low in the engine, worst under load and pulling away
• Oil pressure falling, especially hot at idle
• Warning light flickering at low revolutions
• Bearing metal or bright flakes found in the sump or the filter
• Shells found scored, wiped or with the overlay worn through to the backing

🛠️ Service Notes

• Ordered by size grade, not by mass — confirm the grade from the crankshaft or the last rebuild record before committing to the Std D set
• Have the journals measured before fitting: new shells on a worn or out-of-round crank will not last
• Big-end bearing kit 859807 is normally renewed at the same time
