    Got a tight fitting hex key and tried to undo the gearbox filler plug on my Freelander TD4. It took a fair effort when it turned until I realised that the plug was still seized and I'd rounded the hex. Any help out of this one would be appreciated!

    Or heat it up, take it for a drive, then try it.

    I had the same problem with the transfer box once as it was a metal plug I welded a socket to it and got a long bar and with it being hot from the welding it came off. hope this helps

    Just can't understand why they tighten the gearbox and IRD plugs up so tight:eek:
    Anyone would think they are holding about 500bar of pressure !!
    From memory, it is an 8mm A/F allen key that fits them.
    I fitted a copper sealing washer under the heads on mine and tightened them up about the same torque as would be applied to a sump drain plug. I did not use any thread lock or sealant on the threads and have not had any leaks or issues.
    I have the sneaky suspicion that they do them up with an impact wrench at build after they have filled them with oil and then fit the complete engine/transmission unit into the car.

    answer was "we never change the gearbox oil" ..... ( never ? :eek: )

    I once changed the rear diff oil in a high mileage freelander, the STENCH was unbelievable!
    I have never smelled anything so bad, and I would wear ep 90 as aftershave.

    Thanks for all the tips. Sadly working most of the bank holiday weekend so won't have chance to let you know how I got on at least for a couple of days. As for welding, the plug is nylon. I feel like drilling the thing out.

    the plugs are metal and you have to be care full not to catch the body of the gearbox or ird and I never heard of a plastic plug on a gear box in all of my life. or maybe I am getting to old for this game

    Cant see plastic plugs being tightened to the extent mine were....needed a breaker bar to shift them. They must have been close to 100ft.lbs torque !! :eek::eek:
    They should definately be steel that's fitted.

    Irwin tools set? Have used these time after time to remove rounded bolts... I know the feeling, has happened to me when I least expected it then it sets you back a few days sometimes weeks esp. when you planned to finish the work by a certain date or day,
    here's me removing one rounded bolt...

    The gearbox plugs are ally, and an 8mm Allen key hole, they often are tight I think its the material theyre made from, you could try hammering a slightly bigger torx bit in and seeing if it grips or try tapping the plug round with a chisel, I don't think there'll be much room to do that though.
