32.2.8. Balancing Shaft

A balancing shaft is a group, which is composed of a balancing shaft body and a balancing shaft weight. The balancing shaft is connected with a crankshaft by a balancing screw coupler. And the balancing shaft weight is connected with the balancing shaft body by a fixed joint.
