I think he was meaning Babbit, not Wabbit.
Id probably melt out the existing Babbit into some kind of crucible or a cup fabbed up from some pipe. A wire rope shop should be able to supply some extra Babitt to make for enough to repour,just need to seal the bottom of the holes up to contain it.

Babbit is bearing material as far as I know. You sure that's not just lead? Probably doesn't matter one bit, just curious. Either is going to shrink a bit if you pour it, so it will have to be pressed into place. I'd try either a large shop press, or a tool of some sort to place on the "soft metal" and smack it with a sledge hammer. I wouldn't be brave enough to hit it directly, but that would work if you're not afraid of missing.

I was thinking about shrinkage, i wonder if theres a ridge or some kind of deformation in those holes to grip the babbitt

Shouldn't be too hard to pour new lead or babbit or whatever it is. The key will be giving them plenty of preheat, then wrapping them up so they cool slowly.
