Which tool for this Kuwahara Bottom Bracket
I might have answered my own question here, but which wrench do I need for this kind of bottom bracket cup on the NDS? A pin spanner doesn't look like it will securely fit the bill. Whatever it is, I don't own one. I have the wrench for oval DS cup.

You need a "lockring spanner". The Park HCW-5 is typical.

For the LH cup (and not the lock ring) the Park HCW-11 is the sort of current tool. Park use to make the SPA-4 (forget the right number, yellow handle with squared off ends). But since this cup interface isn't common these days the "best" tools are long ago out of production. Andy

You need 6 tools:
1. Something to pull the dust cover off.
2. A 14 mm socket or Park CCW-5 crank bolt wrench
3. A Park CCP-22 crank puller
4. A HCW-5 lock ring tool
5. A HCW-11 adjustable cup wrench
6. A HCW-4 fixed cup wrench.
I would also suggest using this method for bottom bracket removal. Removing the fixed cup side is counter-intuitive but it is easier since removing the fixed cup is usually the hardest step that is made harder without the spindle in place.
I would also suggest that you replace the bottom bracket with a cartridge bearing unit. Less maintenance and longer unit life.

Hello to responders, thank you for the input. I should have clarified that the tool query was for the keyed NDS cup and not the lockring. I would usually swap this old BB out for a cartridge but I want to run a thinner grease down there for winter riding. I do the same for the pedals and hubs. Makes a big difference in energy expenditure, especially the hubs. I'll pop in to a local coop and do the repack work there seeing as how they`ve the tool.

Park used to make a tool called the SPA-4 which is a slotted spanner with a yellow handle. They don’t make them anymore and they are rare. In a pinch, you might be able to make one of their pin spanners work. This spanner might work but it is horrible expensive.
