Craftsman 34473 Engine Crankshaft

The Craftsman 34473 Engine Crankshaft transforms the pistons reciprocating motion into rotating energy that drives the engine through its combustion cycle. During operation, it turns in coordination with the connecting rod assembly allowing mechanical force to pass through the internal rotating mechanism in a continuous sequence. Positioned within the lower area of the engine block, the crankshaft rotates on bearing surfaces and aligns, with surrounding internal parts. Its structure includes partially machined journals and integrated counterweights that are used to maintain steady rotational movement while the engine is active.
