ATV Crankshafts

What is a Crankshaft?

Crankshaft is the component of an engine which translates reciprocating linear piston motion into rotation. To alter the reciprocating motion into rotation, the crankshaft has "crank throws" or "crankpins", additional bearing surfaces whose axis is offset from that of the crank, to which the "big ends" of the connecting rods from each cylinder attach.

How Crankshafts Works?

The crankshafts converts the up and down motion of the pistons into horizontal rotation. The shaft is one solid piece made from cast iron or forged steel. Steel is usually used in high loading situations, such as diesel or turbocharged engines. Oil passages are either cast or drilled into the crankshaft to distribute lubricant to the main and rod journals.
