DA7700 Shifter stripped screw advise needed
I went to change the shifter cables on my DA7700 equiped bike and the little
screw holding the cover over the shift cable end wouldn't come off. I managed to mangle it further. Images are below, any ideas how to get the little screw off? After using various tiny philips screwdrivers and I tried small straight bladed screwdrivers. It won't budge. I can't get a small pair of vise grips on it, screw head is much too small and rounded. Thanks to all, Rick. http://home.comcast.net/~expansive/stripped.jpg http://home.comcast.net/~expansive/stripped_b.jp |

It may loosen up a bit if you give it a light whack dead center with a tiny punch and a light hammer; I'd do that prior to slotting it with the Dremel. Heat is good. A gas torch might not be a good idea but an 80W electric soldering iron applied to the head of the screw will help. Slotting it carefully with a Dremel cutoff wheel as suggested above might be the only way to get a grip on it once the heat has loosened up the corrosion holding it. If you don't have a Dremel tool now's your excuse to get one, or a cheapo $20 imitation. PH |

Kinchrome make a small size bolt extractors called Kwick Outs, you need a reversable power drill to use them.
