Old School cranks!!

[Quicksilv3r]

Hey im busy taking my moms steel Peter Allen frame apart to get it sandblasted and given some new paint! I took everything off today but I honestly have no idea how to get these cranks off!

 

 

 

My modern ones just slip off with a little tool i got but these don't! do they have a tread? Does anyone know how to get them off?

 

Thanks

Haha ya I did that just put it on for the picture so you can see! I think it might just need a fat hammer put to it but just want to make sure im doing it right.

you get a crank removal tool. the bolt you see unscrews from the bottom bracket axel.

rather take it to the bikeshop(and a good one at that) as you get shimano and campy removal tools, but also TA and Stronglight (amongst others). the treads are different and you can stuff up the cranks if you use the wrong one

the crank removal tool will (after the bolt is removed) screw into the threads in the crank, and push in on the bb axel, forcing it to go out.

 

you can also try a bearing puller

That won't work if the threads are stripped.

 

One way apparently is to loosen the crank bolt while the bike is still built up, and give it a couple of power sprints up and down the road. In my case, the bike was in pieces and i was prepared to sacrifice the old stripped ultegra crank.
