In Reply to: Datyl, Kaegi, Jeremy, it IS a balancer- posted by Chris Case [173.245.48.192] on Sunday, April 23, 2017 at 09:44:59 :
It's a harmonic balancer. The flat spots are for clearance so you can install the fan belt. Used on all passenger cars at least through the early 50s. The B series trucks use them also.
