Guys,
Thanks for all the input, before I went to bed last night, I dropped it into
a tub of WD40.
This morning some of the seals pried out fairly easily. The bearings came
out after heating the linkage and pressing them in the vice again.
The one that gave me all the grief, eventually came out after I turned it over
and pressed out out the other way. It seems that the last time they were
pressed in, they were not squared up correctly, resulting in a "lump" being
created by the leading edge of the bearing that it would not get past.
(buying a used bike has it's surprises)
Anyhow I fixed it / smoothed it out... all is good
I owe you all a beer!
