Crank Removal

Leadballoon

Can't see how this works at all.
I'm trying to remove the chainset from my Gary Fisher Cake (its a Bontrager Select) and inside the left hand crank arm it is threaded for a crank puller, however the axle is completely hollow. This means that there isn't anything for the centre part of the crank puller to "push" against.The cap is just a single 8mm hex, not one of those two piece bolts with an 8mm inside the 10mm that effectively does the work for you.
Hope I've explained that clearly.

Anyway, can anyone help?

Thanks

Hit it!!!!, with a rubber mallet or plastic hammer.

In the past I've slid some deep sockets down the axle (keeping the crank retaining bolt on the other side), This has allowed the tool to push against something solid to get the crank off. Then to remove the other crank, replace the bolt from the removed crank and repeat to get the other side off.

Hope that makes sense!

Hi, I did manage to get this off but it was only because I was able to take the crank end bolt (one of those 8mm/10mm combination things) from another bike. Thanks though Gezebo, that was my next port of call. I was going to post a couple of pictures to see if there was something I had missed but I've no idea how. I'll try and learn before my next problem.

Thanks

then it is self extracting.
