Question 1

What does it mean to have oversized bearings?

Accepted Answer

When an engine is rebuilt, the crankshaft journals are often machined to remove damage. This makes the journals slightly smaller. Oversized bearings compensate for this material removal, maintaining the correct oil clearance.

Question 2

What other parts should I replace when replacing rod bearings?

Accepted Answer

At a minimum, you should always use new rod bolts. It's also smart to inspect the connecting rods for any signs of damage or wear. If you're already this deep into the engine, consider replacing the main bearings and oil pump as well.

Question 3

How do I know if I need oversized bearings?

Accepted Answer

Consult your engine builder or machinist. They will measure the crankshaft journals after machining and determine the correct bearing size needed to achieve the proper oil clearance. Using the wrong size bearing can cause serious engine damage.
