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

Ooh, nice puller!

Dayam! Indeed it is!!!


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.

That probably isn't a high-speed pulley (Woodmiser, innit?)
I'll bet it would braze up nicely...if the pulley isn't bent from the
abuse the first time around.

Thats a cast iron pulley. Braze the busted part back on, clean up on
the lathe (inside of the groove..the outside ..dont bother)

Done a gazillion of those and it works nicely.

You can even tig braze it easily.

Silicone bronze or Aluminum Bronze works nicely.
