210 pixel repair - Removing gauge needles

I am busy taking apart the display cluster to reach the infamous temp and time displays. To reach these lcd's I need to remove the gauges but can't get the needles off. I dont want to pull too hard as this will damage the motor that drives the needle. How are the needles removed?

I know there are kits available on the internet that contain replacement ribbon cables. Apparently these kits have detailed instructions on how to replace the ribbons. Does anybody possibly have one of these instruction booklets?

I've done that repair a few times.... The kit will have instructions but you just need to pull against the needles as you twist past the stops, you wont hurt them. I carefully scrape the circuit board with a razor, emphasis on the carefully, before using a pencil eraser to clean the contacts on the board You have to use plastic to scrape the old residue from the glass, and that is quite tedious. When instructed to cut the frame, and as well as when you snap things back together, you have to be very careful. A shockwave through the plastic can destroy the LCDs. They don't tell you that.

Or you could send it to Beckmann Tech and they install a better LCD set than the cheapo factory did....... Malaysia, Taiwan, India or where ever they bought them.

Thanks that did the trick!! Thanks for the advice too! Have ordered the cable and hopefully it will solve the problem. These displays are designed very badly. The big display has a quality connecter and the other displays have useless zebra cables. The plastic moulding desing is also too complicated. The overdid parts and completely neglected others.
