Jan - the advice I received from the factory is that the Tufnol
bearings should NOT be greased or oiled. My inspector confirmed that
oil is a BAD THING here - it collects dust which then turns into
grinding paste and destroys the bearing. I did put a thin film of
non-silicone furniture wax on mine, but as it's not tacky it does not
tend to collect stray particles in the same way as grease, and does
not migrate easily like oil.
I'm trying to visualise how you're getting your eye in position to
see the gap between CS06 & CS07. Even if CS06 is not bolted in (so
you can get your eye close to CS05), the flange of CS07 must prevent
seeing daylight in the gap. But that's not important, obviously you
have a gap from the evidence of play in the system.

If you remove the CS07 from CS05 (and heat, perhaps a hot-air gun, is
the way to make Redux give way) how will you be able to position the
rivet holes in the new CS07? You want them to align exactly with the
original holes in CS05 so the rivets will hold. I can't think of a
really easy way to do that. Maybe CS05 could be clamped in position
with vee-blocks on a drill-press table to align correctly with the
drill bit, and then CS07 slipped on to be drilled. For subsequent
holes, the first hole would need to have a rivet inserted to keep the
alignment correct.
>Another question is whether replacement CS06 from Europa will be a better fit
You could ask the factory to supply a pair of CS07-CS06 and ask that
they be checked for correct fit before dispatch.
