Attaching crank arm with Shimano SLX M660 Wow jimirings you mean you put Loctite on the taper itself? I can't actually believe you got it apart at all! I would be expecting to need something like a 5 ton press to get that apart, good to hear it didn't break anything. |

Attaching crank arm with Shimano SLX M660 That is pretty much what I assumed originally, the nut is a piece of plastic. Having reassembled the system by the book (with the same old plastic nut as I'm still waiting on the Ti version) it seems to be holding together okay. One detail, since the shaft is a slip fit in the bearings it seems that the torque on the nut is intended to preload the bearings laterally enough to force them to turn with the shaft. From the original install I can see the shaft had polished on the (plastic!) bearing surfaces. Still the pinch bolts should be enough after it is assembled to maintain that preload... |

Attaching crank arm with Shimano SLX M660 Thanks Benzo, I will probably loctite the pinch bolts, haven't decided on the cap just because the diameter is large and once it sets it'll take an act of war to detach. Have you ever had problems? As I mentioned to Ken above, I went ahead and bought a metallic cap (titanium) so the bond should be effective. |

Attaching crank arm with Shimano SLX M660 Thanks Ken, interestingly the document you link suggests periodically retorquing the retaining nut, as though it coming loose is an expected part of its service life. Re material strength, I would hope that aluminium would still shear off before the harder steel. Nonetheless since they are all relatively cheap and before I had any responses to this I shelled out a few dollars for a titanium cap that should still be softer than the steel. Hopefully this doesn't turn into a big mistake. Also nice that it has a hex drive. |
