Skip,
This is a pretty easy fix. You should have the exploded parts diagram
in front of you, as you are working on it.
I would use a blow dryer or heat gun to warm the grease. Olympus used a
grease that dried out, and looked and acted like glue. You will need to
remove all of the old grease, and re-lube. I believe that I used axle
bearing grease for the project, but I suspect that any light/medium
quality grease would work.
Here is a previous post on the matter:
When the grease gets that hard, don't try and force the parts apart!
Use a
heat gun (or a big hair dryer) to get the area very warm. The grease
will
usually soften up enough to get the parts to separate with a modest
amount
of force. This is a very common problem with microscopes since they may
sit in a lab unused for years. An Olympus microscope tech showed me
this
trick when I was trying to service some microscope parts. It works
incredibly
well.

Hope that helps!
