I had a cracked small bevel gear and a missing woodruff key. After reading on the site here I bought a new gear from Pistonbikes, but cannot find the correct sized key. I was told to get one 1 size too large and file it down. No problem until I look at the size onthe shaft and the gear. The slots are 2 different sizes! I have 1 woodruff key that fits sloppily into the gear, has wiggle room from side to side, but that same key does not fit the slot on the shaft. is the woodruff key supposed to be 2 different sizes or is it made to fit sloppily in the gear slot. What the ****is going on? Not to mention no one sells the small bevel woodruff key.
