What is the primary function of main bearings in an engine?

Main bearings support the crankshaft within the engine block. They allow the crankshaft to rotate smoothly while maintaining precise oil clearance, which is essential for reducing friction and wear.

Do I need to measure my crankshaft journals before installing these bearings?

Yes, it is highly recommended. Measuring the crankshaft journals ensures they are within the manufacturer's specifications for size and roundness. This helps guarantee proper oil clearance and prevents premature bearing failure.

What is the typical lifespan of main bearings?

The lifespan of main bearings depends heavily on proper installation, oil quality, maintenance schedules, and driving conditions. When installed correctly and with regular oil changes, they are designed to last for many years and miles.
