Cast Aluminum Bracket Repair

So, I had a alternator/power steering bracket on my Truck, which had a broken bolt-hole.


I already had a replacement on the truck, so, I decided to take a chance, and determine if I could repair the part, by only using filler rod.

So, I threaded a steel bolt into the hole, and started building filler up all around it, careful to heat the aluminum, and not the steel.


After the filler was added, I unscrewed the bolt, and used a flap disk to smooth out the part.

While, I could have added more filler on the outside, and grinded it to a flat surface, and, did a slightly better job of grinding the curves, I am happy with how the repair turned out. It should have no issues holding the alternator on now.
