Crank puller to get the crank off.
Lock ring/c-spanner to get the lock ring off. Drifting it off will do the trick too, unless you slip.
Suitable spanner to get the cup out. Can't remember the size, it's been 20 years since I took one of them out. An adjustable should do it at a push.
And probably a 32 (?) mm spanner to get the right hand cup out. An adjustable will be an utter pain on that side, as it's only about 3mm wide, and only 2 flats, so not many attempts with a slipping spanner before you have to drill it out.
