    Hi. I have 105 Hollowtech II cranks, and the correct PT BBT-9 tool, but cant even get the adjustment cap off of the left arm. how the hell does that thing come off. the adapter fits in the 8 spline cap, but i cant turn it. i wish i still had campy. much easier.

    Did you loosen the crank bolts first?

    that cap has probably (of course , its no consolation to you) been

    overtightened.

    the cap only gets fitted to a little more than finger tightness. it's made of plastic and i can't imagine how you'd overtighten it without stripping the threads (plastic) out.

    did you assemble it yourself? if not the person who did it might have put some loctite on the threads which is preventing you from breaking the seal.

    theres really not much to it, remove cap, undo the two pinch bolts and the assembly all comes to pieces. typically takes less than a minute and is much simpler than campag square tapers.

    i've got two spanners for the outboard bb removal. they both have inbuilt end cap tools on the reverse end. one of them has the equivalent of a torque wrench in that once you get the cap up to the correct tightness you can't tighten it any further as the the head then spins. the other doesn't have this feature. if you can find one without the torque function i'd try giving it a few taps with a hammer to see if you can break the seal on it.
