    A modern bike with a cup and cone bottom bracket?

    You will need a hook spanner and a pin spanner. Pin spanners come in different sizes, but theres an adjustable one

    the lock ring takes the hook spanner. the pin type is used to adjust the bearing preload and hold it in place as you tighten the lock ring.

    Are you sure that is the exact BB? I checked your specs and it appears different.

    Yes! Sorry everyone for the confusion, I'm new at bicycle repair and I'm learning. I can see some of the threads sticking out the left side, what tools will I be needing to fix it?

    There are supposed to be a thread or two sticking out the left side, if it is the BB shown in the picture. Is the BB axle loose? If not, there nothing to fix.

    No, nothing is loose. If that's the way it's supposed to look then I guess I'm fine. This is why I love this forum. Thanks everyone.
