    XTR crankset adjustment nut?

    Hey all,
    All the tech info that I can find on the XTR FC-M970 crankset says to install the left crank arm and then tighten the adjustment nut to adjust play. Take a look at step 6 and you'll see where they describe how to adjust the nut. Am I supposed to adjust it out towards the crank arm to eliminate any play on the spindle or what? I'm searching the forums now but so far no luck in answering this.

    Thanks,
    Mike

    No -adjust it in toward the BB bearing. When the non drive crankarm is tightened it seats - positive stop. The nut is to eliminate the crankset from shifting side to side. Once it is set is does not need to be adjusted. Mine went a year without a problem.

    Thanks sscyco, but I'm a bit worried. Your location is Spokane so you're probably a Coug fan. That means you're probably not too bright and would like nothing better than to see a Dawg fan mess up his bike. If it's alright with you I'm going to hope for a second opinion. Plus, you are fool o' crap by your own admission.

    All kidding aside, I found this document that tells you to make sure that the adjustment nut is against the crankarm when you put it on. So, is someone can confirm what sscyco has said I'd appreciate it.

    Thanks,
    Mike
