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?

The lower bolt is in place and tight?
All the fan blades are intact? Alternator pulley out of round / bent? Maybe you need to get your belt balanced. (IMG:style_emoticons/default/hide.gif) |

(IMG:style_emoticons/default/hide.gif) I have an idea that I'll be looking for a new alternator in the future. I have noticed since the repair that the alternator is making a pretty loud whining noise. Maybe a bearing issue. Anyway, if I'm going to install a seat heater in the car, I might need more of them amp things to work with. Till then it's producing 13.8 volts at low rpm. I took my belt into NAPA and they balanced it on their dynamic belt balancing and tension setting machine. You should get one of those for your shop. (IMG:style_emoticons/default/biggrin.gif) |
