    Titanium Pivot Bolt Broke Off

    I know others have experienced this but this was my turn. I was servicing the pivots for the first time on my 6-month-old TallboyC. The top pivot on the upper link broke off as I was torquing it up to spec. I tried for a day to drill a hole for an easy out and was not successful. I took it to a shop today and they could only drill it out from the back side through the axle. An Easy Out jammed into the axle allowed it to be turned enough to remove it. What a pain.

    Has anyone replaced the titanium bolts with something that allows the proper torque? I have heard stainless mentioned but I don't know if anyone has done it. If so, what size bolts and where did you get them?

    Thanks,

    Ted

    Contact SC directly. They'll set you up with a proper bolt gratis.

    Titanium Pivot Bolt Broke Off

    ^^^

    Contact SC. They'll take care of you. I broke the top shock bolt torquing it. Luckily I was able to thread it out with the other broken half. SC sent me some stainless replacement bolts.

    I have contacted Santa Cruz and new bolts are on the way. I am concerned that this will happen again at some point and I do not relish a repeat. I may try to find a replacement bolt.

    I don't torque those bolts to spec. I use a healthy amount of blue loctite and set them about 10-15in/lbs below spec. Have not had a problem.

    which ones are titanium? are you talking about the bolt that tightens the wedge in the collet? I was pretty sure those were aluminum. the shock mounting bolts are titanium though

    The bolt I broke is the hex head that tightens the wedge. Maybe it is aluminum (which would explain why it broke so easily) but it was sure hard to drill out.

    I purchased a Tallboy Carbon Pro Pack from my Santa Cruz shop. It includes all of the bearings, axles, bolts, etc. for the pivots. On the label are the M5x0.8x20 bolts used for the upper pivots. They are listed as 18-8SS (stainless steel). I removed the bolt that had not broken and found it to have stretched about 2.5mm. I replaced it with one from the pack. I guess they are not buying quality bolts or got a bad batch. At least Santa Cruz supplied replacements at no charge. To be safe I just torqued the bolts to 70in-lbs (spec is 100 in-lbs).
