Hi,
This ones been niggling me for a bit so I thought I'd ask. Many years
ago I bought a crank removal too from halfords (The one you screw into the
centre of the crank and then tighten the bolt in the middle to pull the
crank arm off) and used it successfully for the job I bought it for. I then
changed my chainsets and came to remove the new one for some reason. I
did'nt look carefully enough at the bolt running through the centre of the
tool and did'nt notice that it was to large for the bolt holes in the crank
arms and it did'nt come to bear on the end of the tapered peg. The result
was stripped threads. Is there any reason why this bolt should be too large
? I've always used road bikes, maybe it an MTB or BMX thing. Any help
appreciated.
Cheers,
Bruce.

I have never come across either of those cranks. We work on used
bikes. Cranks like that haven't yet trickled down to the utility/
commuter bicycle lot.
As to why the shop has a crank puller for ISIS and Octalinks is beyond
me.

The bigger one is for pipe billet cranks - ISIS or Octalink.
You work in a shop and don't know this? Scary.

I have come across this problem as well. At the shop I where work I
have found two different sizes in bolts that push against the
spindle. There is no difference in the threads that screw into the
cranks. I did a number on a crank before I noticed a difference in
size but I didn't strip the threads. I don't know why there are
different sizes, I just make sure that I always use the smaller one.

Did you remove the washer from inside the crank arm after taking off
the fixing bolt?

Yup, I just checked it against another crank (shimano biopace) and the bolt
does'nt go through the hole.
