Cydrome Leader fired this volley in news:nj9g7l
:

The only thing that would make even a lick of sense is there were
unshielded bearings in there originally and that's why there were grease
ports. Why the thing was pumped full of grease later is a mystery.

Anybody seen anything like this before?

I think what makes more sense is that someone replaced the bearings with
sealed. Later, someone ELSE, not realizing there were sealed bearings in
there, and seeing the grease nipples, reasonably assumed it was intended to
be greased, and did so. shrug
