2. If you don't have the proper pin spanner, a small punch and light hammer can be used in the holes to turn the cups.
3. A modern (either cup and cone or cartridge) bottom bracket may fit if the threading is standard "English", "Italian" or "French" and if the bottom bracket shell is a standard widthe like 68 or 70 mm. The length of the spindle will be determined by what replacement crank you choose.
Thanks for your answers!
1. It's a good tip and I wish I was aware of it before hitting so much with a hammer....that's my mystake. Now the clotter is badly damaged and hitting with a hammer seems hopeless. I will have to find a special trick to remove it
You're right about the spindle, it will be hard to saw....that's tricky !
2. I don't really want to harm more the bike...I might get a proper tool which is not so expensive anyway
3. Sounds good! Will check out the exact dimensions when I the 2 first issues are sorted out.
Cheers
Ben
