    Advice on removing bottom bracket fragment

    Exploring a persistent bad noise on my Cross Check, I discovered that my BB was shot. It came out in pieces -- except for one, which remains stuck in the threads of the shell. What's the best way to remove this? Hacksaw? Thanks in advance.

    Oh my. What bottom bracket did you have in there?

    I'd be wishing I'd had a Shimano UN-xx with the much hated plastic adjustable cup right about now.

    Yeah, very curious what brand that was? Aluminum or steel cup? DS or NDS?

    And, sorry. I am at a complete loss right now for a suggestion on how to get that out.

    @AnkleWork: If you look closely, you'll see threads, then the hoop-shaped remnant still in there, about a centimeter wide, then more threads.
    @lester: It's a step up from the Shimano thing, but the same item basically. I believe it's an IRD,
    @Squid: You're looking at the NDS. The aluminum receiver. I'm thinking using a hacksaw or file to saw gently through it, or almost through it. Then pliers. Alternatively a Dremel. Alternatively a hand grenade. After that, the LBS.

    Try your luck with some penetrating oil, than a large EZ-out. If it's stuck where the threads are LH, it's more problematic since EZ-outs may not come that way.

    If you have a Dremel and access to hex stock or a large enough hex head bolt, use the Dremel tool to cut 6 points into the ring, to fit the bolt head, then use a pipe wrench to turn the bolt.

    Problem solved: A couple of cuts with the hacksaw down to the threads, a pop with a punch to break that section off and the remainder of it came out with a little pliers persuasion. The new one -- with the plastic receiver -- went right in.
