Shimano HT2 tool does fit, but mine was tight, bloody tight, I had to virtually hammer it onto the old BB. Shame is ( if mines typical) is marking your old bb is no problem, I wouldn't like to scrape the paint off a new one. But...needs must.
Forgive me if I'm stating the obvious ... Don't over tighten the preload bolt, it'll ruin the new bearings pronto.
