    Hi everyone, I'm trying to remove my gearbox and the small, square headed grub screw that holds the shift linkage to the transmission is a sod!
    Does anyone have any tips for their removal? I have shifted the transmission to 3rd for better access.
    It would be a lot easier if it was a hex head rather than the square head that no socket will fit.
    Why do they use the square head ?
    Tips please
    Darren

    Maybe slip the ring of a large ring spanner over the shaft of the shifter and use it as a cheat bar

    It is a 8 mm open ender spanner. Has the wire that prevents it from undoing been removed ?! I assume you would of already done it as the wire is in the head of the grub screw.

    Thanks everyone for chipping in. With all of the above tips and some patience, it came loose. the hardest part is that there isn't much room to get to a spanner onto it squarely. Is there any reason why a hex bolt couldn't be used to replace it ? Then a slim socket would get to it better?
