[Farmall] 39 A: Crankshaft pulley with setscrew!

[cvill]

In my case it was a gear, Al.  The space behind the gear was limited to 
about 3/8".  I had nothing to get in there so I bought the splitter.  I 
used it with a hook end puller set up with two jaws, hooked under the 
outer edges of the splitter.  the gear pulled off with almost no effort 
on the puller bolt.  I have used it on my 20 ton press behind shoulders 
as well.  It has worked as it should.  The problem you might have with 
your pulley is the  pin or tab for setting timing as someone mentioned 
in a previous post.  There is no opening is the splitter to allow for that.
