🔌 Function

⚠️ Common Signs of Failure

• Deep rumble from low in the engine, worst under load
• Oil pressure low or falling away when hot
• Metallic glitter in the oil or on the filter element
• Shells found scored, wiped or with the overlay worn through
• Crankshaft end float or clearance measured beyond limit

🛠️ Service Notes

• Measure the journals and check clearances rather than assuming standard sizes, as bearing kits are graded
• Clean out the oil galleries and renew the oil and filter before the first start
• Bearing cap 3884522 and its screws are listed against the same engines and should be checked at the same time
