Perhaps I did something wrong and ordered the wrong tool,,,, I did use the tool for the lower sprockets and it worked, but the upper sprocket tool looks like 3 pedals on a flower.... The sprocket was keyed,, The tool would only go on one way but even that way was not quite good enough to slip it over the end,, I had to grind on the "pedals" quite a bit... The tool is still useable but mods definitely had to be made,,,, Are there several "pedal" designs??? Please let me know for future use thank you, Mike
