Steel Balls in Crankshaft?

[Gerrha]

Just pulled the crankshaft in my 97 1FZFE and I see a couple of steel balls in the crankshaft itself. They must have some function with oil flow, but what?

How do they get those put in place and do they need to be cleaned and/or replaced?

Photos of their location on the crankshaft would be helpful

Sorry. I would have attached photos before, but I figured everybody but me knew instantly what they are. Here are three.

Those are used to plug the holes drilled to create the internal oil passages.

Well OK, thanks for that. I guess they do not need further consideration.

Apologies, but this is all I could think of looking at the post title...

I just wanted to see the location of those balls. We use to use "Mallory Metal" in the crankshaft throws to balance the crankshaft, so i wanted to see if what you were talking about was something along those lines.
