Hi,

You say "The ninth bearing did not have room to fit.",
but of course there must be room for it to fit but you
have done something so that is does not appear to fit.

Is inanely unhelpful on the subject.

One possibility is the bearings are not the same size both sides, which
makes some engineering sense to me, but I don't know if its ever done.

rgds, sreten.
