    Spinning shroud bolt in tank?

    I dont think the bolt is stripped, i think the metal part inserted into the tank is spinning.

    Any ideas how to get it out without ruining the tank?

    Thanks

    I had this same problem, i heated the metal with a gentle heat gun then pulled the bolt out with plyers. this leave a bit of a mess in the tank so I shaved off the plastic crap and then filled the hole with araldite glue and pushed the metal lug things back in. good as gold. just remember dont wind it tooo tight.

    What he said except I use a bit of lube on the threads

    if you can get the schroud off you can either grind the bolt head off then using vice grips after it has cooled unwind the thred, or just heat the bolt and let it cool, these threds need some anti seize on them and dont over tighten, if the captive nut re welds its self in you are in luck, if not get it hot again and pull her out, just to state the obvious here......the tank has gas in it, and is flamable.

    The cause to this problem is over tighting the bolt and also i have found with others they had left there bikes in the van or hot shed then went to work on them and the insert started to spin in the hot now soft plastic tank.

    Its best to just pull the metal insert out clean up both surfaces and use a 5 min epoxy. Also i use anitsize on the threads.

    if your not replacing the plastics undo the rest of the bolts and leave shrouds attached to the tank and take tank and shrouds off as one piece, Less bolts and inserts to loose and takes less time to remove.

    Got a soldering iron handy? Apply that straight to the fitting and see if that helps. Could try adding a bit of solder to help with heat transfer.
    Don't go over board though!
