Before these two backup plates cracked did you notice if the pointy end was on center with no wobble? Did the trailing edge of the backplate wobble before using the washers/spacers? Approximately how much wobble was observed? Was the engine ever rotated with only the backplate bolted in place (no spinner installed) to check for runout of the trailing edge of the backplate? Was the runout measured and, if so, what was that finding? Thanks for your contribution, Doug.
