I currently bought an old Motobecane in fairly alright condition. However, the rear cassette is in fairly poor condition with rust and I would like to change it. It is an 6-speed cassette, but I am not familiar with its attachment onto the axle/freewheel. The axle itself has screw threads throughout the axle, and there are freestanding ball bearings within the freewheel. There seem to be a circlip with 9 "teeth", but this is just a wild guess.
Anyone familiar with this attachment? Which tools are applicable?

Teeth don’t look too worn. I would say just clean up the rust and ride it!
If you already have the hub open, clean and repack grease: [https://www.sheldonbrown.com/tooltips/hubs.html](https://www.sheldonbrown.com/tooltips/hubs.html)
Uniglide cassette. Finding a replacement will be difficult. If you’d like to remove it for cleaning, you’ll need two chain whips. One on the smallest gear, one on any other gear. Small gear goes lefty loosey.
Further: If you do remove the axle and bearings to clean and regrease, the freehub body (together with the cogs) likely will just slide off. Many earlier, low-pecking-order freehubs did not have a separate internal bolt holding them on.
