A jackshaft, also called a countershaft, is a common mechanical design component used to transfer or synchronize rotational force in a machine. A jackshaft is often just a short stub with supporting bearings on the ends and two pulleys, gears, or cranks attached to it.ackshaft [edit]. The oldest uses of the term jackshaft appear to involve shafts that were intermediate between water wheels or stationary steam engines and the line shafts of 19th century mills.
Report Abuse. The crankshaft is a major part of the Internal Combustion Engine, invented by the Muslim inventor Al-Jazari in the 12th century (see last note). The first cars did not have an electric start, and no way to prime the pistons. To do this a person had to rotate the engine's main shaft. To get the mechanical advantage to rotate this shaft a crank lever was hooked onto the end of that main shaft; thus it became the CRANKSHAFT.
