What is a Fully built Crankshaft?

These types of crankshafts are made by creating the different parts separately and assembling them together. In such a type of crankshaft, all the parts are shrink-fitted after the fabrication process. These are mainly used in old types of engines. Crank web, crankpin, and the main journal are made separately and then the crankpin and main journals are machined and bored in the crank web. The crank webs are then heated and fitted into the crankpins and journal holes. As it gets cooled, the diameter of the borehole fits properly and firmly.
