CandoBrent, A screenshot of the 1953-57 6 cylinder engine exploded diagram for the crankshaft and related areas from Page 103 of the 1957 Master Parts Book doesn't show a "slinger" of any kind on the crank shaft. There are 2 crankshaft gear keys shown for installing the gear and then the damper over that to keep things from spinning on the shaft. Did you perhaps not use 2 keys when you installed the crank gear?

Definitely post a pic of your "slinger" as I can't seem to see anything in the resource books to ID one.
