Yes you need to get it removed. Try a hammer and chisel to free it off and hit it round a bit. Remember that if your bike has a standard 68 mm bottombraket shell the non drive side is LHT (sorry if you know that but I have met people that have been riding for a long time and don't know that).
Edit: my mistake drive side is LHT. I always need to work it out.

damn... more rideing on the fucked bb then untill i can get round to banging it out.

So have you manged to remove the locknut on the non drive side?
If so and you are planning on throwing the old bb away there should be enough threads exposed for some pipe grips should to grip onto and twist the bugger out. They should not slip and will have good leverage.

oh and im not really clear as to weather the bb is french, ititalin, or american threaded (mostly beacues i have never gotten the non-drive side cap off. its a fuji from the 70's any one know?

no i think its the nut thats stuck

messure the bb shell 68 mm means euro / british iso
70mm mean italian
I would guess english / iso.
American b.b are not threaded at all. Still found on some bmx bikes, (but they have largly moved over to spanish / mid bb) and alot of beach bike with one piece crank.http://www.sheldonbrown.com/gloss_bo-z.html
Sheldon has the answers!

right so i mashed up my BB playing polo, and have decied instead of buying more barings, im going to fit the sealed bb i was given. now i can get half of my old bb caps off (the drive side caps) and i broke my lock ring tool on the non-drive cap. if i take the plastic non-drive side bit off the sealed bb, and just screw in the metel one from the drive side will it hold, or do i need to head to the lbs, and see if they can get the other cap off?
