For Sale is a conversion from belt drive to chain drive for you sander / spreader.  It includes everything you need to go from belt drive to chain drive for ONLY the main belt NOT the spinner belt.  The roller chain is Stainless Steel. (I have other kits available to replace both belts and in plain steel chain.)You get 2 sprockets (Engine & Clutch,  Stainless Chain (with master link), and 1 key for the sprocket.  It will fit many sanders, not just Fisher Procaster.  Email me for more information on different models if you are not sure.  Fisher Procasters have 1" Engine Shafts.  If you have a different size, I can substitute sprocket sizes.  Chains will not slip, the most common complaint on most sanders!  Very Fast Shipping!
