I wish I could post pics, but I am a computer fool, co I will try to explain. while repacking my secondary bearing, obviously on the clucth side I noticed a hariline crack in the casing if you will that the bearing is in. It is like a donut or a collar and it sticks out of the frame a bit and is round. I am not sure if this is part of the bearing or not. I have never replaced the bearing as there is no play in it, but this crack is making me wonder..I dont think I have every heard of this topic here. Any help or suggestions?
