Introduction
Main bearing clearance is a critical factor that directly impacts the performance, lifespan, and reliability of your engine. By optimizing main bearing clearance, you can reap significant benefits, including reduced friction, improved oil flow, enhanced power output, and extended engine life.
Understanding Main Bearing Clearance
Main bearing clearance refers to the precise gap between the crankshaft and the main bearings. It allows for sufficient oil lubrication while preventing excessive wear and damage. The ideal main bearing clearance depends on various factors, such as engine type, operating conditions, and bearing material.
