Bottom bracket tools?
#1
I'd like some advice on what tools I'll need for this bottom bracket (see attached photos). Ultimately I'd like to re-grease or replace it.
Thanks so much for you're help!

if you do not work on bikes much but want to do it yourself, I would not worry to much about the spanner/lockring wrench and spend your money on a crank extractor, this will pull the arms off this spindle and the new cartridge BB spindle in the future. so yes i recommend updating to cartridge style BB instead of the cup and spindle you have now.
spend your money on the tool to put in the new BB instead.
So all you need to remove the lock ring is a pipe wrench or careful taps with a hammer and a screw driver so you do not gash your frame, and a wrench to fit the nut on the bearing cups, look at tutorials to get the feel of the process
There are two kinds of people in the world, "Those who help themselves to people, and those who help people!"

I agree with PK, I'd replace the existing bottom bracket with a cartridge type, they're much easier to install and last ages.

You'll need to pull the cranks off, for which you'll need a crank puller, like this:

This is a genuine Shimano crank puller and I recommend it, I have one and it's much better than the unbranded one I had previously.

Like PK says, you can "bodge" the existing bottom bracket out by undoing the lock ring by tapping the lock ring around with a hammer and an old screwdriver, then undoing the inner part with a large adjustable spanner.

You'll need to measure the length of the bottom bracket axle, then get a cartridge bottom bracket with the same length axle. The Shimano UN54 or UN55 aren't expensive smooth running and last for ages:

To fit the cartridhe BB You'll need a tool like this:

Some are like this, which you use with a large spanner, or some have an integral handle, like this:

Maybe, but I never had one, even the better quality and more expensive ones, run as smoothly or last as long as a sealed cartridge bottom bracket. Even though I used plenty of good quality grease and would take the time to adjust them "just so", I don't think I ever got much more than a year out of one. I think it was mainly the lack of sealing, so water and dirt would find its way in and end up pitting the bearing surfaces.

Maybe sealing is less of an issue in dryer parts of the world, but if you ride in the UK, you and your bike are going to get wet at some point. Smile
