When the mechanics pulled the prop, they discovered a 3-inch crack in
the spinner and two incorrectly-sized bolts used to bolt the prop to the
hub by some unscrupulous mechanic during the last prop overhaul, which
resulted in elongation of the bolt holes in the prop hub. Most likely
the prop hub is beyond tolerances and will need to be replaced. The
spinner will certainly need to be replaced given the size of the crack.

Ouch! My condolences. I guess I shouldn't whine so much about what a
battery just cost me.

What kind of engine replacement are you doing? Factory o'haul or...?
