Bottom Bracket Foibles

I'm trying to remove my bottom bracket to clean it
and such, but I cannot get it off. The problem seems
to be dual.

1. I don't seem to have the proper tool.
2. The bottom bracket cups are frozen. I've removed
the lock ring but the cups just aren't moving.

Anyone have any suggestions. I've included a link to a
photograph so you can see what type of tool I'd need.

Why don't you just bring it to an LBS and have them do it?
While you're at it, you could probably replace the bottom
bracket with a sealed cartridge BB as well. That's what I do
most of the time.

Not sure what tool you need, but the LBS probably has it ...
and look around this site too:

Don't forget, the drive side is a left handed thread.

The tool you really need is this:

Park's SPA-6 two-pin spanner may not be up to the eask in
this case, though it's sometimes a suitable choice. If it
were me doing the job, I'd grab a crummy deep socket that
was big enough to fit over the shaft, grind it to produce
a pair of tabs to mate with those recesses, and use Power
Tools to haul that cup out of there. You may not have
that option.

I have seen people attack such a cup with a punch and a
hammer, pushing it around while badly chewing up the slots
and often rendering the whole thing irretrievably mashed;
I would not recommmend such a procedure, and mention it
only cautionarily. (This is not to say that I have not,
with great delicacy and care, used such a technique
myself...but I don't know your level of skill, and it
takes some skill, and sometimes a bit of luck as well, to
get away with that trick.)

Don't forget to also use Liquid Wrench and some patience.
