Be very careful with stuck bushings on the change gears! They are very weak in tension. I have broke two of them, and they can be a real pain. They are made out of a strange metal, probably zamak, that is like concrete. It is very weak in tension, but comparatively strong in compression. That means that your gear puller must bear against the bushing/sleeve, not the shaft. Replacements are available on Ebay, but they are pricey. Note that you do not need these stupid sleeves to make another one on the Craftsman 109. In fact, that can be your first project. :rofl:
