BMW 330i Crankshaft

The BMW 330i Crankshaft takes the straight up and down thrust of every piston and converts it to the smooth spinning force that keeps the drivetrain going. Set deep in the engine block, the Crankshaft receives sharp impulses through the connecting rods, then evens them out so power reaches the transmission in a steady flow. Bearings bathed in pressurized oil allow the Crankshaft to turn with very little friction, and strong steel or cast iron construction means that it will typically go for the life of the car without scheduled attention. Across the years, 330i sedans have relied on two main Crankshaft styles, cast units and forged ones, each made by precise casting, machining or forging methods. Cast versions, found on earlier BMW production, are more cost-effective, whereas forged steel shafts are applied in later 330i models to cope with increased stresses and revs due to their denser grain structure. If oil pressure falls, the Crankshaft journals may scar and seize. Regardless of style, a healthy oil system and intact seals are vital, as a loss of lubrication means that wear will quickly spread and can cause damage to the BMW powerplant at its core.
