Engine Description: Crankshaft

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.

The crankshaft is forged micro alloy steel. It is supported in 4 main journals with main bearings which have oil clearance for lubricating. The thrust bearing is located in the 3rd position which controls proper crankshaft axial end play. The crankshaft is also comprised of 6 counterweights that have been scalloped for mass reduction and topped for precise engine balance. A harmonic balancer is used to control torsional vibration.
