Cramkshaft Turning Socket
Suit SB Ford, Buick & Pontiac With 1/2" Drive

1.385" ID with 3/16" and 1/4" keyways. Engine work requires repeated crankshaft rotation. This non-marring, aluminium tool rotates the crankshaft the proper way, when the balancer is off. Making sure to have the proper size, position this socket over the end of the crankshaft, so it can be turned using a 1/2" breaker bar or drive ratchet.
