Hmm... how to disassemble the cassette guts...
Make a cassette gut spanner wrench, of course!
I disassembled the cassette guts, which spun on 52 ball bearings, 26 per side. I removed and discarded the ratchet pawls, and drilled a small hole for a grease port. Then, using sticky assembly grease, I carefully reassembled all 52 ball bearings. A shot of grease, and the thing turns either direction smooth as silk. This will be the business end of the jackshaft support.
