Good news and bad news.  I got the pulley off with a good tug.
Unfortunately, the nipple the pulley sits on broke off with it.  This
is the nipple that's part of the bracket.

Any ideas?  I've got it bolted on for now with the broken off piece in
place, but I'm leery of this setup.

Would some JB Weld and red locktite do me for now?

Is this "bracket" an individual piece or is it part of one of the other
accessory assemblies?  I can't really tell without pulling stuff out,
and I don't have a shop manual.

Thanks in advance,
David
