i had to pull the oil tank out of my 914 to address a leak, and one of the mounting studs on the tank broke when i went to remove the nut. it broke about a 1/4" off of the tank.
quick google search last night didn't yield any good intel, what am i looking at to replace that stud?... |

I've fixed this problem before on 911 tanks. You'll need to carefully grind the broken stud flush to the the tank and clean the area to bare metal.
The only proper way to re-attached a stud to metal this thin is to carefully braze a new stud on and it will be as strong as the original The tank is too thin for electric welding in my opinion even TIG is a challenge due to the vast differences in material thickness. Also getting rid of all the oil or rust contamination for a proper electric weld is near impossible, brazing is much more tolerant in that regard. |

(IMG:style_emoticons/default/agree.gif) This method done with either welding technique is the way to go. BUT.... evaluation of the attachment is area is imperative. A trusted, experienced welder can do this....or suggest other remedies. |
