Thanks for the reply Andy!!!
Do you mean a burr on the crank or the sprocket? How hard is it normally to get these things on and the crankshaft? I thought it would be pretty easy !

Depending on the crank mfg, they can vary from a light slip fit to a slight press fit. I use a gear puller, which is the proper way to remove it, but you can also have some success "warming" the gear with a propane torch. Don't go crazy, just a little heat will get it done.

What Andy is referring to, I believe, is that there are burrs that form on the keyway slots of the gear that will cause some issues with fitment. You can dress those down with a small file.

FWIW, I'd rather have a gear that is a slightly tighter fit than loose.

I heat the gear to about 250 degrees in the oven and it slides right on.
