Crankshaft and crankshaft bearing

What is a crankshaft and what is its function?

The crankshaft is a central component of a truck engine and converts the up-and-down movement of the pistons into rotational motion. This rotation is transferred to the wheels via the drivetrain. Because the crankshaft operates continuously under high loads, proper fitment and lubrication are essential for reliable engine performance.

What are crankshaft bearings and why are they important?

Crankshaft bearings support the crankshaft within the engine block and ensure smooth, low-friction rotation. They carry the weight of the crankshaft and absorb forces generated during combustion. Worn crankshaft bearings can lead to reduced oil pressure and serious engine damage.
