Hi Mike,
Heights Tower Systems makes them for their towers and supposedly can
make them to order, if need be:

*"Pulleys* - - We have pulley sheaves of stainless, aluminum and steel
material, with and without bronze bushings; we also have aluminum Roller
Spools. Diameters run between 1.75" and 4.5". Call factory for prices,
including some special clear-outs. Here are a few examples. If you need
custom pulleys, please forward drawing or dimension specs for a
quotation. We specialize in aluminum with bronze inserts."
Odds and ends:

I found a couple of bad pulleys today on my HG70-HD. On one the bearing has
visible cracks around it in a regular pattern, on another the bearing is
completely gone. Still have 2 to check. I had bought replacements from
McMaster-Carr a bit over a year ago. They are steel and the bearing is fairly
thin.. I had one used pulley in my junk box which has a much thicker bearing,
not sure if it was an original.
ANYhoo, I need a source for new pulleys, and a reason to the failure of these
two.
