Removing Cranks (amateur question!)
I'm trying to change my dad's bike from a double to triple. I've got all the parts but have stalled getting the old cranks etc off.
It's a 2011 Claude Butler San Remo
The centre of the cranks had plastic caps and a bolt underneath. I've removed the caps and removed the bolt from each side but can't get any further. The cranks have not been released by this.
Can anyone suggest the next move???

You need a crank-puller:

You'll need to fit a new bottom bracket to fit a triple chainset - the existing one almost certainly will be the wrong size.Make mine an Italian, with Campagnolo on the side..0 -

Cheers. Will I get a crank puller in the LBS?
Bb is the only part I don't have.0 -
You'll get a crank puller from LBS / Halfords / online. (possibly in order of decreasing cost) Just make sure that when you removed the crank bolt you didn't leave a washer behind. Unscrew the central bit of the crank extractor far enough to allow you to screw the outer bit fully into the threads in the crank. Then tighten the central bit back up again and off pops the crank!
Do you have the tools to remove the old BB and fit a new one?0 -

Picked up the crank puller and cartridge bb tool today at the lbs. |Succesfully managed to get it all removed.
Now found out the BB I have is an exterbal (?) one and I need another different tool to install it. :-(
Getting there though!!!0 -
And you need to get the BB shell faced. LBS job."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

Read the fitting instructions that came with the BB. Of download them from shimanos webby or read the info on Parktools
Or read this viewtopic.php?f=40073&t=12654663
Must sort out the missing pics."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

I can not see why he will need the BB faced. I know that it is recommended if you are going from internal to external bearings but he already has external bearings.
If there is some aspect of this that I am ignorant of I am happy to be educated.0 -
