You'll have to get a new bottom bracket that matches the thread size and spindle length of your old one. It can be tricky so I recommend taking your old one to a bike shop to size up a new one. Keep in mind the Truvativ bottom bracket uses a special splined crankset. Sheldon Brown has a great database sizing page that may help: http://www.sheldonbrown.com/bbsize.html It may work.

Some says that's an old type. Can I replace it with a new one: Truvativ Powerspline? Will it fit? I have the same type of bottom bracket. Some says that’s an old type.

Where do you get the training to become a bicycle mechanic. I can build and repair and tune but not as well as I think I can. Thanks Hey, I’m a bicycle assembler for a national corporation.

I ended up using a pair of vise-grip pliers to remove it. I wasn't worried about ruining it since I was intending to upgrade to a newer variety of BB. It turned quite easily so I can see how maybe one of those spanner tools might work as well. For the side with the lockring,my 30/32 headset wrench fit perfectly - I was surprised I actually had a tool that fit ! I used your other video for installing my new type of bottom bracket. Not sure I picked the right size bottom bracket for the type of crank arms I ordered (Bulletproof model). In process of attempting to learn what chainline considerations I need to take into account from Sheldon Brown's website. Alex.

The main problem with too much of a difference is that one leg would be further out than the other, so I think you'll be ok with only 7/16". A small difference like you’ve described is acceptable.
