After the lengthy thread about alternators, I decided I should look into why mine is rattling so badly. This is the second bracket that has broken in less than a year. I was thinking of welding it back together and adding a doubler in the form of a washer or just fabricating a whole new one out of thicker steel. Any ideas why it might have broken in the first place? Is it possible I tightened the belt too tight? Is it possible it is vibrating so much it fatigued the metal?

Couldn't help but notice that the hole was oval. What caused that? Was it loose once?My rule of thumb minimum; the distance between the edge of the bolt hole and the edge of the metal should equal the drilled hole diameter. You've basically corrected that with the washer and the welds resulted in nice filets which will add strength.

QUOTE(76-914 @ Oct 2 2016, 02:54 PM)  Couldn't help but notice that the hole was oval. What caused that? The hole was actually made like that, to allow for adjustment. When I cleaned and painted the sheet metal on my engine last winter, my bracket had the same slot. |
