    Lefty Helicoil?

    I removed the front wheel today to have the wheel trued at my LBS. After getting the wheel back, I found that I am unable to properly tighten the hub bolt to the Lefty spindle. The bolt keeps turning and won't completely tighten almost like something is stripped. I researched this issue and found others with the problem apparently related to a helicoil inside the spindle. When I examined the spindle to check the threads, I couldn't locate a helicoil at all! Did I lose the helicoil when I removed the wheel in the lawn? What now?

    Please help.

    The Lefty is a 2008 Lefty Speed DLR2 110mm.

    Thank you.

    It's likely stuck on your hub bolt.

    Remove the cap (it's reverse threaded, FYI) and get it off of the bolt.

    It's a 10x1, same as a derailleur hanger, so a decent shop should be able to set you up quickly. Otherwise, a motorcycle shop or auto garage should too.

    We had the hub apart at the LBS. The helicoil is not on the bolt. I guess I will need to check into finding a replacement helicoil.

    Thanks, Craig!

    I'm still trying to get mine replaced. Problem I'm having is finding the M10x1 size kit. Seems to be very uncommon in any world outside of bikes. And the ones I do find are big kits, $100 and up. My LBS did get the helicoils themselves from Quality, so I think the install tool from, say, an M10x1.5 (which I find all over) will work to screw the coil in. I'd like to run a bolt or some sort of thread chaser carefully in it just to sort of clean the threads that are cut into the axle itself. So...maybe a rear derailleur bolt might work to do that, given what MendonCycle says?

    Part # TL1800 from QBP.

    Q's description of said item.

    "10 x 1mm Helicoil Thread Repair Kit
    For rear derailleur hanger
    Includes insertion tool, drill bit, proprietary tap and 12 inserts"

    That's the whole tool kit.

    No, a derailleur bolt will only thread with the Helicoil installed. Without it, the threads ID will be too large.

    As for the 1 vs 1.5 kerfuffle, no idea, but der hanger threads have been 10x1 forever.

    Tried a motorcycle or auto repair shop yet?

    Thanks for the additional info! I've been trying auto parts stores. From kits I've seen, all seem to come with the insert and the tap, but not all come with the drill bit. The drill bit seems to drive the price way up...$100+ with, but those without are in the $30-40 range. But I can't find a kit without the drill bit in the M10x1 size. Anyway, almost there, and have a couple more questions.

    - Am I correct that the drill bit should not be needed here? The axle is already drilled, so I think just running the tap through carefully to clean the threads is all that is needed?

    - When installing the new helicoil, should there be any thread locker applied to the spindle threads &/or the outside of the coil? And if so, any particular kind?

    Thanks for the help!

    Nope, shouldn't even need to run the tap through, just install and go.

    Nope, you don't want that, if you ever want to extract it at least!

    Thank you for posting this additional information including the QBP part number for the repair kit.
