I had to pull a pulley today, so I took pics of the operation:

Note the special three piece puller bracket. I also took a smaller one
apart to show the three views and set it beside the pulley. I should
have made one first, cause I tried to pull without making this and
broke a piece off the pulley.

Can this be welded? What special procedure, looks to be a forging or
possibly just cast (I doubt it but don't know how to tell for sure).
You can see rough grain in the broke off piece.
