Thanks all. I was mistakenly focusing on the slot (at 12 O’clock) in Jeff’s pic, which the Arrow cassette does not have. And I was reading “roate the bearing” as somehow rotating it within the cassette to align some non-existant tabs on the bearing with the slots on the casette.
Joe’s description made me realize I have to “pivot” the bearing out of the casette, then twist it to align with the slots to aid in removing from casette. Using the axle as a tool to pivot the bearing out did the trick.
Thanks again to all of your generous help!
