Use a Crescent or other wrench on the tool, and strike it firmly a couple of times with a dead blow or other hammer to break any corrosive bond in the threading with impact. Once you have the drive side and the BB sealed unit out, you'll have better access to the plastic cup you're having trouble with, and maybe you can just cut it in a couple of spots and break it out from there.
Thanx, appreciate the tip. The plastic lockring on the NDS was fused in tight. First tried the splined tool and stripped teeth. Second, chiselled until seeing that wasnt working and risked jimmying threads. Next, heated a chisel and melted as much was left and gave the removal side (drive) which is metal and integral to cartridge. Many taps later it came loose. Put the new BB in and is now back to riding condition.
Thanx for all the tips and suggestions.
