    Geabox selector rails.

    Hi,
    I'm in the process of changing the gaskets between the adaptor and gearbox and adaptor and overdrive (a significant amount of oil keeps leaking out around the bolts).
    There is also always a small drip of oil on one of the selector rails. Is replacing the O rings on the selector rail a job an amateur would be capable of doing or is it best left alone? (I feel sure that I read an old article that suggested to leave overhauling the selector rails to a professional, but I can't find it again). Or can you get away without removing the complete selector rail system to replace the rubber seals?
    Thanks
    Mark.

    You have to remove the selector forks and deal with the detent springs.. Not rocket science.

      I have done a few of these over the years, the biggest job is getting the pins out of the selector forks without snapping them off, this has only happened once and fortunately I had a spare cover from a scrapped gearbox.
      Unfortunately sometimes they still leak so I generally don't bother unless there is a lot of leakage, but then I park on gravel at home so most of the time I don't know!

        Thanks very much all. I’ll ponder this one.
        Another daft question if I may. From reading, I can see that you have to remove the drive flange if you want to separate the extension on a non overdrive gearbox. Do you still need to remove the drive flange if pulling the J type overdrive and short adapter off the gearbox?
        Thanks,

          No, on non OD I guess it needs to slide over the output shaft but on OD the whole OD unit comes away including the Drive flange.

            Thanks,
            I thought that was the case. Then reading the ROM and Haynes manuals again I started having doubts.

              Some time ago a member did this job using o-rings supplied by a well known specialist. The rails leaked much worse afterwards. we managed to source viton quad seals which worked well. I only wish I had written the sizes down. Can anyone help with the sizes please?
