What do oversized rod bearings do?
What Do Oversized Bearings Do? Whenever we bolt our main caps on to engines, we create a larger hole, for oversized bearings to fit in. As a result, all mean bearings are aligned correctly, increasing bearing life, reducing crank vibrations, and reducing stress.
How do I know if I need an oversized rod bearing?
When Would You Need To Use Standard Oversize Bearings? The material surrounding the bearing housing bore is denser when it appears undersize. If the bearing has been milled into a bigger diameter or lines bored, oversized bearings are applied.
