    need a bolt extracted

    picked up a frame over the weekend. has a crankcase adjust bolt that goes through the back motor mount stuck in the frame. was able to remove one of them with an impact gun. no thread stripping, just most likely seized on there from heat and time sitting. the outbound side where you'd use a 19mm socket after removing the castle nut was already stripped from the shop that disassembled the bike. the inside of the bolt stripped on me last night with a 12mm hex bit. i've used heat. i took a grinder off to the edge and tried with a big ass pipe wrench. it's really stuck in there. guessing the outbound side might have been peened a bit and now is stuck.

    so where can i bring this to get extracted? i'm in the south shore.

    here are some pics of the bolt, so you get an idea

    Re: need a bolt extracted

    Drill it to round it out? Then tap it with a reverse thread and use another bolt to get it out?

    That should make it that much easier to do it the way I mentioned.

    if it stripped from a 12mm hex socket using a 3 foot breaker bar and a massive pipe wrench with heat, it's really stuck in there. dont think a drill would extract it out.

    Re: need a bolt extracted

    Maybe try heating the local area around the bolt and then spraying some duster in a can at it upside down to shock it?

    You could take it to a machine shop, I'm sure they'd come up with something.

    The shop would most likely just drill it out almost to the thread and then just peel it out.

    Just trying to save you a trip and some money. Either way, it doesn't sound like you're understanding me correctly.

    Good luck, cupcake...

    How do you think a machine shop will do it?


    It's not magic.

    I took my aluminum brembo brake calipers to coughlan because when I backed the steel bolts out the aluminum threads came with them. They had been THOROUGHLY heat cycled too

    Re: need a bolt extracted

    dropped it off to a local guy.

    i know i could drill it out, but i dont trust my skillset on doing that without messing up the frame threads. that's something i'd rather pay a specialist to do

    I would count on the frame threads already being FUBAR, heli-coils are pretty foolproof to install

    maybe. i was able to extract one of those thrusters and the frame threads were fine.
    i'm ok with doing helicoils. i did one on my radiator mount the other day. this would be a large helicoil though. like M21 if they even make them that large. just not something i was comfortable doing.

    I've done em for spark plugs, I would also send out something I am not comfortable doing. the other option is an insert, I had a machine shop do that for me once

    Re: need a bolt extracted

    For those interested, the guy fixing Jim’s frame is my guy in Raynham, MA. He’s a retired machinist who has a small machine shop in his barn, he can also weld anything. He’s the “no job too small” kind of dude and is very reasonably priced. Located near the I495/Rt 138 interchange, I’ll be happy to put you in touch.

    Does he do frames with rim locks?

    Sometimes you gotta go the other way - cold may get it loose rather than heat:

    Same idea, but with penetrant. I've have used it before and it does work. YMMV.

    Re: need a bolt extracted

    Late to the conversation but I would have suggested having someone tig weld a decent sized hex head bolt into it. The extreme heat from the welding process is far greater than what a torch would give while also being localized heat. It tends to open the gap between the the threads of the existing bolt and the frame section. A few seconds to let the weld set and then apply torque to the bolt head. It's what most of us have to do with those POS brake caliper bolts after somebody rounds off the hex head.
