- Remove the connecting rod cap nuts and gently tap the cap to separate it from the rod.
- Remove the old bearing shells from both the rod and the cap.
- Clean the bearing surfaces and install the new bearing shells, ensuring the locating tangs are correctly seated.
- Apply a liberal amount of engine assembly lubricant to the surface of the new bearings.
- Carefully reinstall the connecting rod cap and tighten the nuts to the manufacturer's specified torque sequence and value.
- Reinstall the oil pan with a new gasket, then refill the engine with fresh oil and coolant.
Troubleshooting & FAQ
What are the signs of a failing big-end bearing?
Common symptoms include a persistent, deep knocking or rumbling sound from the lower part of the engine that increases with RPM, low oil pressure readings, and potentially metallic particles found in the engine oil during a change.
Is this kit for one connecting rod or the entire engine?
This kit contains the bearings for a single connecting rod (big-end). For a full V8 engine rebuild, you would typically need eight kits. Please verify the exact contents before starting your project.
Are these standard size bearings or oversized?
This kit contains standard size bearings. If your crankshaft has been machined, you may require oversized bearings. Always measure crankshaft journals and compare with OEM specifications to ensure you order the correct size.
What causes connecting rod bearings to fail?
Failure is most often caused by oil starvation, contamination of the oil (with fuel, coolant, or debris), improper installation, or simply high engine hours and normal wear. Maintaining clean oil and proper oil levels is critical for bearing longevity.
