Abstract
A method of balancing a crankshaft includes connecting a torsion-absorbing pendulum to a cheek of the crankshaft, which is coupled to a crankpin. As the pendulum connected to the cheek has insufficient mass to balance the crankshaft, a lightening bore is formed through a bisection plane of the cheek. In forming the lightening bore, enough material is removed from the cheek so that the mass of the pendulum becomes sufficient to balance the crankshaft.
