Beware of jumping right in & taking the bottom bracket apart. Why do you want to do that? (I only ask because it sounds like you're new to this...)
Thanks to all those who answered. Yes, I was thinking as a pipe wrench as the last resort.
halfbiked, I am new to this, but I want to learn without going to the store. I would like to replace the bottom bracket and the crankset eventually so the pedal turning would become smoother. That may also involve replacing the cassette assembly.
