906 Alpino Chainwheel crank removal?

[stevel]

Hi, After three years I am having to replace the chainguard and also investigate the loose chainguard bracket and pedal sensor (believed to be secured by a fixing ring) Now my immediate problem is the removal of the crank. I have undone the 14mm bolt at the centre to reveal a square section shaft upon which the crank sits. A few of questions;
1. Is the pedal crank an interference fit on the shaft?
2. Do I require a special puller?
3. Is there a tip on how to remove the crank, short of being an animal about it with a length of wood and a heavy mallet?

A speedy answer would be nice, before I break something.
Thanks

A length of wood and a mallet is what I used on my wisper. They are a interference fit, and they often get a little rusty, and that's why they need a bit of assistance to remove.

Don't do it with anything other than a crank puller otherwise there's a risk of bending the BB spindle. You'll need the BB tool too. Don't forget aout the LH thread on the BB. Here's both:

Great just what I need. Just ordered one.Thank you for that. I have managed not to break or bend anything so far, this will do just the job. Will the securing ring that hold the bracket and sensor require anything special? I am trying to anticipate any problems.
