thanks Nate...it all makes more sense now that I have it apart. I ended up using a map gas torch to heat the top up hot enough instead of the heat gun, bearing came right out
too bad I have a cobbed up cover now, pretty annoyed with myself. Knew it was something simple. Hopefully I can make it look good, being that the hole is on the back side, it should be ok. I have several inquiries out there for a new cover however. Need a new 6902Z bearing... once it gets back together, I know the top bearing just needs setting enough for the circlip, then both gears should spin freely right?
Thanks for the support!
