Alternator rebuild kit

Posted

Started the other day and it's been squeaking a bit, I'm assuming the bearings are going out and I'm don't want to pay $100+ for a parts store special. 

 

Are the rebuild kits from genos garage good? And how do I tell if I have the denso or Bosch brand alternator? 

 

Thanks.

    We sell the Denso alternator diodes... This will give you a clue. Bosch diodes are soldered in.

I didnt know that, But that helps! I'll be looking closer at mine when I get home from town to find out which I have. 

All my trucks I've had over the years the tag was still on it telling what brand the alternator is.

Actually ended up ordering the hi-amp rebuild kit from them, I'll build and leave feedback on the post.

So just wanted to give an update, I did order a kit from http://rebuilderinabox.com/ for the denso and put it on Thursday, when I got out of work Friday I drove 20hrs non stop to San Diego and the alternator hasn't made a sound or had any charging issues. 

Glad I did the bearings, the ones I pulled out where on there last leg.

    That was one of the things I wanted to do was source out the parts for doing alternator rebuild kits for the website. One of the many things no longer sold in a normal part store.

    I performed the ground and positive cable mod on my Cummins and it didn't make a difference in my new torque converter lock/unlock issue. My alternator is putting out too much noise and I want to replace it before it burns up my billet torque converter and anything else electronic.

     

    Can someone post the part number for the Denso diode kit, and the hi amp alternator upgrade? I was looking on their site for my 99 Cummins alternator, but then the one page said no kit and no price.

     

    Thanks!

    This site sells the heavy duty diode bridge replacement for the Denso alternator. Just click the store at the top of the forum page.

    That's a great price for the diode kit. 

     

    I finally found the upgrade section. What's everyone's thoughts on installing the high amp upgrade on our alternators when we install the new diode kit?

    One or the other... Can't do both. If you update to high amp alternator you cannot use our diode kit. Diode kit only fits the stock Denso alternators. Bosch alternator has solder in diodes. 

     

    There is a few members here that opted for high amp alternators to hopefully get away from the issues. Unknown if it has resolved the AC noise issue for most are just getting started in mileage and time.

    The diode kit does not upgrade the amperage of the alternator. You need a new higher amp alternator to do that.

    Mike said in his post above, that I couldn't install his diode kit and the high amp upgrade on my Denso alternator, he said it had to be one or the other. 

     

    I just wanted clarification if that was correct or not.
