Stripped case threads
 

Hoping someone could point me in the right direction. The threads are stripped out most of them came out with the bolt not sure e of the thread size its the big bolt with the 17mm head.. So what the normal fix for this? I'm not a fan of helicoils. Can I put in a time sert? If so what size? Or tap out to the next size up possibly a sae size.?...
Thanks in advance

M10 x 1.5 timesert

same as the cylinder studs .. i just happen to have that kit

thanks

I had a rear one strip out, I didn't want to buy a 10mm timesert kit for one hole so I used a VW case saver.

EDIT: BTW I know it looks too big, I just remembered this hole had a striped out previous bad helicoil repair and I had to dig out what was left of the original stud. Timesert wouldn't have worked, maybe a big-sert would, but this solution solved the problem.

I've got a couple of cases where the upper driver's side transmission mount stud had been repaired with a Helicoil. Works just fine in the application. I had a transmission mount to body bolt hole with stripped threads and had it Helicoiled. Worked fine for 25 years or more, though I had to replace it recently. I can buy the Helicoil stuff at my local hardware store.

Is the vw case saver the same as used for repairing head stud threads in the magnesium cases?

Yes

Yes but there's a couple of different flavors. Most VW guys use the 8mm 1.25 head stud case saver with a 10mm OD, then there's a 10mm ID x 12mm OD metric case saver and the OS oddball CS in my pic which has a 10mm ID with a 1/2"-13 thread on the OD.

You use the 10mm x 12mm metric CS in the 911 mag case.

Mark,
Thanks for that case saver info, it isn't as easy to find as it seems like it should be.

For inserts in this application, we use custom sized CaseSavers as opposed to TimeSerts.
The material used for standard TimeSerts seems soft and the thread pitch is too fine.
