How did it get damaged? Heavy rust? "Drilling out" a broken bolt?
If the damage affects more than 1 or 2 threads they may need to be restored.
I prefer Helicoils most times. You may need an extra long, or stack 2 regulars to get enough thread engagement.

You can only use this insert to repair one hole per cylinder. If more than one stud hole is damaged then you will need to contact someone like In Place Machining, http://www.inplace.com/
Do NOT use a helicoil, you will not be satisfied with the result.
Hope that helps, MikeL.

10 inches long, drill and tap a 2 inch hole to salvage a 1-5/8 inch thread.

I have an old manual telling that the repair insert is 4c6409. Is the 128-5113 areplacement?
Thank you
