O470 alternator mount

I have a factory overhauled motor ready to install in my 182. The old alternator mount used one of the case through bolts as an attach point and I am really not liking the idea of using that same attach point on the new motor. Is anybody aware of a legal, big continental mount that does not use one of the through bolts? Thanks!

After 2 stock alternator mounts cracked, we went to the one piece engine/alternator mount.

Re: O470 alternator mount

Do you have a part number? That looks way better than the alternatives.

#646748. We had to trim down alternator bushings to fit. Solid.

Looks like Texas Air Salvage has got one.

Re: O470 alternator mount

Ordered the part. Ended up getting it new and it was pricey but it looks like a much better design than what I had. I now know it was actually covered under SK182-52F. Thanks for the help.

Re: O470 alternator mount

FWIW, for future reference to anybody else looking at this issue, SE79-58, supplement 1 was, as far as I can tell, the most recent revision. It references SK182-55F which spells out a bunch of minor parts but also identifies the combined motor mount/alternator bracket as P/N 643935. I got that part from Yingling for $674.

Re: O470 alternator mount

I am lucky that my 180K has the one piece mount as shown by skyward. I found something similar at BAS parts (Beegles) and it must take a different mount leg.
