Quoted message said:Quoted message said:How do I get off the cottered cranks?
A well-meaning poster gave a bunch of bad advice:
Quoted message said:
Loosen the nut on the cotter pin (wedge-shaped bolt) some. Thwack it
gently with a substantial mallet.
No, "gently" _never_ works. Nor does a mallet. If you don't have
access to a cotter press, you have to hit it HARD with a HAMMER.
See: http://sheldonbrown.com/cotters
Quoted message said:Loosen nut again, repeat. If it
resists, thwack it less gently. You will probably damage the cotter pins,
Certainly, not "probably." If you don't hit it hard enough to drive the
cotter out with the first or second blow, the cotter will definitely be
toast.
Quoted message said:but you aren't planning to use this crank, anyway, or so I gather.
It would save a LOT of trouble to use the crank and bottom bracket as it
is. If it were mine, I'd drip a bunch of oil down the seat tube and
ride it.

Quoted message said:Can I buy a cartridge bottom bracket for this frame?
should be no problem. It's probably English threaded, which is the
current standard.
No, it isn't. It's Raleigh threaded, 26 tpi. The only currently
available bottom bracket for this is Phil Wood, which costs considerably
more than the frame is worth.
See: http://sheldonbrown.com/raleigh26 for details and strategies.
Quoted message said:Check that the shell is 68mm wide, and that the
right-hand cup has left-hand threads. If so, modern English (ISO)
threaded bottom brackets will fit. If it's 70mm wide, and the right-hand
cup is right-hand threaded, it would be Italian (unlikely, but most likely
alternative), which is also available.
Italian on a Raleigh? You've gotta be kidding!
