Hello all, and Merry Christmas!

I was changing the transmission mount on my car today, and unfortunately one of the 2 little side bolts on the mount broke off. Does anyone know what would be the easiest way to get that sucker out? I got the other one out and the big 19mm bolt as well (the mount is now out of the car).

Is there a way I can get away with this without taking off the whole transmission mounting piece (L-shaped metal piece, (p/n 855 339 103 C, page 49-10 of the ETKA) that bolts to the transmission and the subframe/body via the mount).

By the way, the small bolts are 6 mm allen bolts.

Thanks all,
Mladen

Cutting a small notch in the head of the bolt, then using a conventional screwdriver to take it out?

Well, the bolt was not bad to begin with. However, when I tried to twist it off with the allen key (with a pipe on the end of it for leverage), the head snapped off.

Since the bolt was in (very) good condition but so severely seized that the heand snapped off, I think that there isn't much chance of being able to get it out with a screwdriver (the force required wold be too much). I appreciate you throwing the idea in, though.

Thanks,
Mladen

A small hole is drilled into the bolt. Once the hole is drilled, tap the extractor into the hole, then remove. You could also heat the area around the bolt with a small propane torch. Letting the area sit with some Liquid Wrench on it overnight before attempting to extract the bolt would also help. If <u>all that</u> fails, drill out the entire bolt itself, pick out the metal pieces, then re-tap the hole for another bolt.

Drill it out, then tap it. It happens to everyone. Have fun ;-)

Sears/Craftsman now has these special drill bits that will back snapped bolts out. They look similar to regular drill bits, but are reverse cut.

Here's a picture of mine.
It comes with various size tapered reverse thread taps. This particular one is suitable for M8-M10 bolts(#2). Use a conventional drill bit to drill a pilot hole in the center of the bolt. This tool taps itself into the drilled hole as you turn counter-clockwise.

In the end, going at it with a drill and tap did the trick (after a few hours).
