I was able to get my 106 degree centerline without any keys. It does take some time and I had to move it a few times to find the right combination. I now have almost 2,000 miles on mine and have no issues. This has been a great thread.
You remember which keyway? or which one relative to the marked one?
There is a little cat logo thingy on the one I think is straight up. But I could be wrong.
reason I ask is that the gear is a tight fit on the crank.
I dont want to have to keep pressing it on and pulling it off.
