arrow To find your Crankshaft choose your Year, Make and Model first.


The Crankshaft is a part of your engine which converts the linear motion of the pistons into rotary motion. The crankshaft does this by means of bearings called crankpins whose axis is slightly offset from that of the crankshaft. The piston connecting rods are attached to the crankpins. The distance between the axis of the crankshaft and that of the crankpins determines the piston stroke distance. The crankshaft is also connected to a flywheel on one end, which dampens the intermittent torque supplied by the rotating crankshaft.

The crankshaft is fitted with several replaceable bearings along its length to overcome the load exerted by the cylinders. The number and position of the pistons in relation to the crankshaft determines the configuration of the engine: straight, flat or V. Some crankshafts are also fitted with additional counterweights to balance out the load exerted by the connecting rods and pistons. The crankshaft assembly is housed within a cast-iron or cast-aluminum enclosure called the crankcase, which is located just below the cylinder block.

Owing to their function, crankshafts are made to be rigid and compact with the ability to withstand high torsional loads and impacts. As such, the crankshaft is subject to failure when any of its components crack or get worn out due to the various forces and impacts which act on them. The surface of crank-pin journals and the crankshaft can become warped or bent due to lack of lubrication, over-speeding, and improper bearing alignment.
