Front damper striped threads

Dougal,
The steel is probably around a grade 4, ie pretty soft, and remember all measurements were in imperial back then

Hi

Sorry to come in late, but thought may be of interest. I went with the Kilmartin camber kit which repaired a stripped thread and hopefully has other advantages. Photo attached

Another nice thing about this adjustable Kilmartin plate are the holes appear to be machine drilled and tapped.

One thing I don't like about the original plates is with the wonky weld nuts, they rarely line up properly and it can be a bee-yoch to get the bolts in on a shock absorber when replacing, it seems like half the time I am cross threading the bolts.

This plate should stop this problem...

Hi All have now completed the repair, went without a hitch: Pics attached:

Thats the new thread waiting to have the insert screwed home. Here is the special tool ready to go.

And the insert in place. To be perfect I should have wound it in another half a turn.

Finally the tools I needed. The inserts in the kit were too long I found that wire cutters were able to easily cut them down to the right length without deforming the coil. In order to drill out the old thread I had to purchase a 90 degree attachment (on the right of the photo. It worked well but you find you need three hands to keep it steady.

Looks good

Dougal,
Are fine-thread inserts available or are they all coarse?

 

[healeynut]

inserts are available in all sizes, including whacky stuff like BSF!

I used 3/8 UNF although as Alan says, you can get BSF.
Have a look at the PDF on Insert Link
All torqued up to 45 Lb-ft fine.
