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.

Probably cast, I doubt a simple pulley would be forged. Probably best to
braze (gas or TIG).

I smell a big favor request coming...

My son offered to stay late at work tommorrow and make me a new one.

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.

Just did the middle pulley:

No way would the puller reach around a four belt pulley. So, i cut a
taper matching one of the shieves in my puller attachment. Don't know
how i could live without my CNC mill.

I'm also glad I took an extra second when taking this unit out of the
CNC yesterday and bolted down a locating block. Then I didn't need to
re center it. Finding dead center on a triangle is tricky.
