Replace Cassette

  1.  Stack sprockets and spacers back in same order (splines guide correct placement; make sure spacers are replaced correctly)
  2. Replace lock-ring
  3. Insert tool
  4. Tighten by hand
  5. Finish with crescent or torque wrench (following manufacturers recommendations)

Freewheel Removal

  1. Insert freewheel removal tool into freewheel, or better yet, into a vice
  2. Drop wheel/freewheel onto tool and engage
  3. Turn the tool with wrench or wheel over vice counterclockwise to break the freewheel free

Replace Freewheel

What happened to the bloody knuckles and swearing involved in a freewheel removal?? Maybe you could do a video of stripping, regreasing and reassembling a freewheel, a true test of patience.

Keep up the good work.

If you look closely, Conor, there’s a bit of a skinned knuckle there; nothing that required hospitalization, but oaths were heard.

Ah, yes, actual freewheel disassembly–springs, tiny bearings, and pawls. Something I haven’t done in aeons.

The last freewheel I can remember rebuilding was a maillard way back in 1993. The only tools required were a hammer, a punch, a freewheel vise, some thread and a tweezers for all the tiny ball bearings. To quote Archie Bunker, “Those were the days!”
