    removing astra G gearknob

    '02 astra coupe 2.2 lift-reverse

    i've removed the plastic/leather surround with a stanley knife and i'm left with just the metal bracket. i read all the relevant posts i can find but i'm still not what i'm trying to achieve with the hacksaw.

    i assume there is a rod or something coming up from the gearbox and this metal piece is either glued to it or threaded on.

    it looks similar to this except the left-hand piece is still attached to my car (found this on forum)

    so...

    1) where am i supposed to cut with the hacksaw ? up, down, round the circumfrence ? am i trying to remove the top bit to release it or split it so it seperates off the rod ?

    2) do i need to be concerned with the lift-reverse (apart from cutting it) or is it pretty self-contained ?

    oh, and i've tried pulling, hamering etc. and it won't budge. need to resort to the hacksaw.

    thanks

    1. All you need to achieve is to be able to open out the current location bore some how, so either cut inwards (vertically) using the stitching as a guide.
    Or horizontally downwards.

    2. Don't touch the lift up reverse bit. You'll still need it with your new gearknob, it's not connected to your old one at all.

    I was lucky and "just" pulled mine off.

    I drilled a verticle hole in the top of the metal bit and then screwed in a big self tapping screw (blunt the end a bit first) - as you wind in the screw the knob is pulled off. Simple

    thanks a lot for the help all. in the end here's what i did... (for future reference)

    i cut around the circumfrence using the ridges as a guide. i basically went in until i heard / felt a change in the saw. At that point i'd hit the steel splines in the middle

    then i just used a screwdriver to prize the top off which released the rest of it. the lift-reverse wasn't an issue at all and the splines on the shaft were in-tact.

    unfortunately because the shaft is kind-of U shaped, and the grub screw on my replacement is at the back, i had to mount it the wrong-way-round :'( looks like i'll have to shell out for an irmscher one after all.

    To get round that problemo - just fill the groove up with a piece of metal or hard plastic cut to fit. - used a couple of thicknesses of old CD (The disc not the box). Stick it in iwtih superglue, and when dry, refit the knob.

    In the end, I rang up Richbrook - the manufacturers of my knob (tee hee) - and found out it is an 'M5' grub screw. Managed to get a 20mm one from a company locally but they would have sent me one if neccessary.
