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?... |

Maybe take a bolt with the same tread, grind the head to about .080" thick. Grind the broken stud flat to the tank. Mig the modified bolt/stud to the tank.
That is what I would try. The extra material provided by the ground head would make it easier, less risky to weld. You could push the puddle formed by the hot head metal to flow into the tank wall material for good penetration without burning through the tank wall. The threads would be clean all the way down the stud to the weld, where as when welding a stud to the broken stud you would have to chase the threads down onto the old stud to get a full threaded stud. Possible but a bit risky and a lot of work. be sure that if you try this to grind off the copper plating that is on the tank. Welding through the copper would ruin the weld. But that is just my opinion and I am a semi-skilled rank amateur. |
