Inspecting the twelve threaded holes for the timing cover I am seeing some damaged helicoils, I would like to replace those, but have no experience in removing helicoils, anyone have any experience as to how this can be done.... without damaging the existing hole ?

Thanks for any and all advice / ideas.

I know "Recoil" market removal tools. These basically have a triangular shaped end ,with the cutting edges disposed so that when broached into the insert the insert is able to be wound out .

You can also use the 'tang' of a file in the same way.

I have used a dental probe to pick up one end of the helicoil and once enough helicoil is out into the hole then wound them in using needlepoint pliers, but only done it on new helicoils that did not install correctly.

Thanks for the tips, I'll try the file tang method, if that does not work, I'll give the dental pick a try .

Thanks again.

I recently removed some helicoils from a junction box on a work class ROV. As long as you can get a grip on the end, they are easy to simply pull out.
