I have an Ultegra splined Octalink crank that I’m trying to remove. I have the Park CWP-6 crank puller, but cannot seem to get it fitted after reading the instructions both on the Park tool website and which came with the tool.
I’ve screwed in the larger rotating head onto the end of the CWP-6, however when I try to screw this assembly into the crank arm (after removing the cap and bolt on the crank), it will not go in – simply because the tool seems to be too long, it doesn’t reach the threads. When I look at a picture of the other crank puller (CCP-4), the end which has the rotating head, seems to be shorter, thus allowing it to be screwed into the crank and pull/push the crank out from the inside. When I remove the larger rotating head (and replace it with the small one or nothing) it does screw into the crank arm, but of course there is nothing exerting any force against the BB to push out the crank. I don’t know what I’m doing wrong.
Any help is appreciated.
