Building a chubby 350 for a chevelle were restoring in the shop. Went to put bottom end together today and found this oddity.
Have never heard notch reference to a bearing before. Interesting, if the picture of the bearing wasn't there, I would not have known what the op was talking about.
It is actually called a "TANG". It only locates the bearing, and has nothing to do with preventing rotation. The "crush" of the bearing in the housing bore prevents rotation.People will call it a notch if they don't know the purpose . It is called a lock because it locks the bearing and prevents it from spinning in the bore. A notch is cut into a surface the bearing lock is stamped in.
The notch would be in the bearing bore to accept the lock that is stamped in the bearing.
Just an FYI
Only 6 days to go. Close enough.Damn.....it ain't even "officially" Winter yet!
LOL. I heard tang several times from engine builders. It is used by many.. I always picture that orange powder drink from years back when I hear them use that word. I won't post a picture of my thoughts of a Twangthis is high comedy.
