Hey Scrod,

I'm trying to remove my Sugino RD cranks. I'm using the Park Tool CWP7, but I can't get the drive side crank off. I haven't tried the nondrive yet as I started with the drive side.

So I take the bolt out, thread in the crank puller all the way, although only with my fingers, and not with a wrench because I don't have a wrench large enough (could this be why?) and start turning the crank puller until it touches the bottom bracket. Then I try to turn it with a wrench, but I can't get past this point no matter how much force I put in. The thing ain't comin off.

Any tips or ideas? My next step is to get a wrench large enough to really tighten the crank puller into the crank threads before I try to start removing. Some people said to tap it with a hammer, but that seems like a last resort to me.
