Replaced the worn 5 hp Tecumseh engine on my Ariens ST524 with a 7.5 B&S Intek Snow engine, but the old 5 hp engine used a 1" bore pulley (4L for auger drive, 3L for wheel drive), the new engine has a 3/4" shaft. Does anyone make a dual pulley in the 3/4" bore size, or do I need to install 2 individual pulleys, and where can I find them?? Thanks all.

I have found some really odd sizes at McMaster-Carr in the past: www.mcmaster.com. I don't know about the double pulley, but I can almost guarantee they'll have the 2 singles; they also have 1" to 3/4" reducer bushing, 1 1/8" long with a setscrew hole.

   A person has given me a reference for 1 inch to 3/4 pulley bushing.  There is also a key cut 3/16'ths and 1/4 to cover the key mismatch.
