Stripped trans mount?

[tevake]

What is a good fix for the captured nut in the chassis transmission mount being stripped out?

Is there a helicoil or insert of some sort?

Cheers Richard

Longer bolt with a nut on the end.

tevake..yes the best is to use helicoil...

never mind 911-rod, you cannot put a longer bolt and nut on the transmission mounts....

I don't think it is a capture nut, but tapped threads into the body. You can use helicoil or timesert.

I did this about a month ago. Use helicoil and some red locktight. worked great. I removed the trans mount to allow more access to make drilling easier. If mounts are dry rotted its a good time to replace them while you are down there.

My apologizes. This won't work. It's been one of those days ....

Thanks for the input Guys, appreciated.

No worries 911Rod, I spent 3 hrs in the dentist chair today. Some days are better than others.

TimeSert it. Not a big fan of helicoils. The kit is expensive so see if you can borrow it from one of your buddies.

Tip: When installing the motor+transmission, loosen the 4 nuts on the transmission bracket before installing the big transmission bolts.

How damaged are the threads? If just chewed up a little, and not completely stripped (sounds kinky, I know! ), you may be able to salvage them using a homemade thread chaser. If you do a google search for "thread chaser" you'll see a lot of pics of what I'm talking about (if you're not familiar with them).

I got one in # 1 heads and one in the body on the driver side for the big transmission mount bolt.

Timeserts are soft. Heli-coils are hard. As much as I don't like H-Cs in most apps, i'd use it there. The problem is that the hole isn't very deep, so when you tap for the H-C, the bottom threads are not finished, so you need a bottom tap to finish.

Thanks John, for that important detail.
I haven't done either , so have some study to do.
About time I learned about these processes.

Yes ChrisBennet, I can see how having to he trans mount crossmember loosened a bit would help.

Oh, I just moved to a new place in Fl. Don't know a single car guy here yet. So totally on my own with this.

Cheers Richard.

I more often found that the bolts were defective and the threads eaten so they wouldn’t hold.
You ll need a 12x1.5x50, grind a point or double washer.
