Internally Balanced Crankshaft at Michelle Lott blog

Internally Balanced Crankshaft. Basically, an engine that’s internally balanced means all weight adjustments are made on the counterweights. This makes the counterweights larger and heavier but also eliminates external offset weights on the harmonic balancer and flywheel/flexplate. The harmonic balancer and/or the flexplate or flywheel can also be weighted. Of course, this assumes that the pistons, rods, etc. Balancing an engine requires offsetting the weight of the pistons and rods, which involves adding or removing weight from the crankshaft. This true rotation or balance makes the crank spin without any additional centrifugal forces that would cause vibrations and lead to bearing wear and possibly catastrophic engine failure. In an internally balanced engine, the extra weight for both balance and inertia purposes is contained completely in the counterweights. A crankshaft, depending on engine design, may be internally or externally balanced. All good race engine stuff is internally balanced, so you don’t have to have the crankshaft balancer or the flywheel or flex plate. An engine can be balanced internally, externally, or using a combination of both. Crankshaft are almost always built as internally balanced assemblies.
