    Upset Mach 6 Trouble

    I think I may be hosed... the #18 bolt on the Mach 6 schematic located here (scroll down to Mach 6): http://www.pivotcycles.com/wp-conten...-All-Bikes.pdf has been completely stripped. I was on a ride earlier in the day and my Mach 6 was making a weird creaking noise. I thought it was about time to remove the links and clean everything, but was unable to remove this bolt because the inside just shredded as soon as I went to loosen it. Yes, left = loosen and right = tighten.

    Any ideas on how to remove it? Help please.

    Not sure I understand... Were the threads stripped or the head? I imagine it's the head. If that's the case I wouldn't panic. There are definitely ways to get that out and a good shop will be able to take care of it. I don't think your frame is hosed.

    Hard to see, but the metal just sheered off on the inside

    Easy peezy to get out. Go to harbor freight or HD /Lowes and pick up a bolt extractor kit.
    They work like a charm.

    Hopefully I can get a local shop to extract it. However, it apparently costs $180 for a new set of linkage bolts that are black. I don't know if I can buy just 1 of the older silver that are on the rest of my bike.

    Speak to Pivot. That looks like something they should see and respond to. It looks like tin foil in there. Maybe Pivot can shout you or discount a new set of pivot bolts.

    You can definitely get one bolt and it can be the light blue type - I had a bearing freeze into one and had to go that route. BTW ck your tool isn't rounded. That and not inserting all the way then turning will see the alluminium bolts shear like that.

    The small parts manual indicates that bolt gets Loctite.

    Try a Torx bit first and see if that'll do it. Find a slightly oversized bit, make sure it takes a little effort to get it in, and give it a go . . . worst case scenario is you strip it worse, in which case a bolt extractor will take care of it.
    Alcohol may lead nowhere, but it sure is the scenic route!

    the easy way for an oversized allen is to use an standard/inch sized one instead of the metric. Usually a close oversize option available

    I used a T30 torx with no luck. I called local pivot dealer and ordered 11 new black bolts and the new HD link for $280. Some of the other bolt heads on my pivot are starting to strip. I might try to use a T30 torx with JB weld and let it sit overnight.

    Just to clarify, all of the suspension bolts are standard threads, correct? None of them are reverse thread?

    Yep, no reverse threads on any of the bikes.

    How exactly are you managing to strip the Allen sockets? Using imperial keys in metric sockets? Over torquing with cheapo keys that don't engage well?

    Are you saying that a set of bolts for the entire bike are are $180?

    Here ya go. We're offering an updated link that's beefier than the original version. You'll also hear it called the "Lawill Link" after Joe Lawill (he's the one who requested a stiffer link, pro level racers can make stuff flex that others can't)

    I have no clue.. I am using a craftsman torque wrench, but I was trying to loosen the bolt and take it out. I was using the correct size and i was able to remove the same bolt on the other side of the bike without problems.

    I've never had the issues you're experiencing but I did lose that same bolt. I called Pivot and it took an act of God to get the bolt from them. They initially said they couldn't help me and wanted me to go to my "local" dealer an hour away and order the one bolt.

    That is nuts... I'd expect 18ct gold plating for that money. At least those bolts come with a free shafting.

    Why can't pivot just give you a dang bolt? I'm a Mach 6 owner, this sounds like a quality issue on the surface reading your post. Wish i stayed with Ibis....

    I can see why the bolts are so expensive. All of them are custom machined bolts. It's not like you can go to Home Depot and buy anything remotely like these. Machined parts are expensive to make.

    At my shop we've sold at least 40 Mach 6s. I don't believe we've had to replace a single aluminum bolt yet. I'd check your wrenches and work with a bike shop on correct torque specs.
