That is what I thought you said originally. THe trouble is, I can't se how
that could possible work. These things are roller bearings
and having them oppose the adjoining one seems to defeat their purpose, which I
assume is to aid in the inward/outward motion of the
slider shaft.
Admittedly, that motion will be minimal after the driveshaft is installed, so
it might not make that much difference at all. Perhaps
the function of having them oppose each other is for having every other flat
end against a different wall of the slider to keep it
positioned properly.
Does that Bentley manual elaborate on that possibility?

Joe
