A better way to remove 3-piece cranks?

[schwinnmesa]

Like, seriously!!! It's just a joke!! I swear, it's the most barbaric thing that I've ever done -- swinging the rubber mallet like there is no tomorrow!!! Is there some sort of tool that I can use to remove 3-piece cranks? It's just such a pain. Is there a better way rather than removing the nut, oiling the bolt, and pounding the crank arm with a rubber mallet? Any help would me MUCH appreciated. Thanks! 8)

Park tool works like a charm. Hammer is cheaper of course.

This is the only way, but a mallet can be handy in addition on some cranks.
Seriously. You're damaging them. :|

Does anyone know if you can get different sizes of the center part that screws into the crank?

I have one bike that the threaded part of the tool is too large for the crank arm threads.

I have one with 2 sizes, lemme see if I can find it to tell you the brand.

Park CCP-1. :wink:

i like the ccp-1. it had standard japanese thread and TA thread on the 'flip side'.

i don't think it's made any more. check ebay maybe.

i believe current park pullers are single thread- one works on square taper spindles, the other has the same thread, but a larger end that won't wedge itself into an octalink spindle if you forget an adapter plug.

old stronglight cranks use yet another thread- that tool might be tricky to hunt down.

even a good puller is inexpensive.

whatever one you get, thread it in to the arm SECURELY before turning the handle.... :wink:

Park CWP-7 is the one you want, I even needed to update to it for some of the newer splined cranks require different tip sizes

There were three sizes in the olden days, Campagnolo (standard), TA, and Stronglight. Only the standard size made it into the eighties and beyond.

I suppose between TA and Stronglight, TA squeaked out a few more years- on 80's Stumpjumpers, tandems, and custom touring rigs.......

And Stronglight finishes a distant third! :mrgreen:

Dave is spot on there, not only did TA make it to the 80's as an early choice for MTB gearing and always the go-to crank for Cyclo Tourist, but they are still in production. Near the end of Stronglight's production they switched to a standard crank puller, TA still uses their proprietary size.
