Crankshaft Key Set 2RZ/3RZ (Set of 2)
Crankshaft keys (also called woodruff keys) are semicircular shaped, removable keys that fit into matching keyways cut into the crankshaft leaving protruding tabs. These tabs mate with matching slots on the harmonic balancer flush upon the shaft. It is impossible for them to roll over in the seat which in turn helps guide the harmonic balancer and prevents the harmonic balancer from freely rotating about the shaft.
