- Thoroughly clean the connecting rod and crankshaft surfaces. Inspect for any damage.
- Apply assembly lube to the new bearing shells.
- Install the new bearings into the connecting rod and cap.
- Use a tool like Plastigage to verify the oil clearance is within the manufacturer's specification.

Troubleshooting & FAQ
What are the signs of a failing big-end bearing?
Common symptoms include a distinct "rod knock" sound from the lower engine (especially under load), low oil pressure readings, and the presence of metallic particles in the engine oil and filter.
Is this the correct size bearing for my engine?
This kit contains the "Std D" or standard size bearings. Volvo Penta also offered alternative sizes (part numbers 876683 and 876684) for the MD2030-C. It is critical to measure your crankshaft journal to determine if a standard or oversized bearing is required before purchasing.
Can I replace just one bearing or should I do all of them?
It is best practice to replace all connecting rod bearings at the same time during an engine rebuild. This ensures consistent clearances, lubrication, and engine balance for long-term reliability.
Do I need special tools for this job?
Yes. Proper installation requires specialized tools, including a calibrated torque wrench, bearing pullers, and clearance measurement tools like Plastigage. Due to the critical nature of this component, professional installation is strongly recommended.
