Noob alternator question
My new alternator should be arriving any day now it's the 70amp Bosch from mercedesshop.
I thought the previous (failed) alternator was an MB but it looks like it's from Kragen. Can I pull the pulleys and fan from the Kragen and install them onto the new Bosch? Maybe the pulleys and fan are MB originals, any ideas? Pic attached. And how do I tighten everything together, it doesn't look like there's any way to grasp the shaft on the alternator. Is there some keyed feature on the shaft that fits to the fan, then I hold the fan while tightening the nut? Lastly, is the thread on the nut RH or LH? Thanks- Rob 79 300SD |

Alternator
Rob -
My alternator took a 24mm socket. If you have an impact wrench, you need do nothing more that hold the fan securely with one hand (perhaps while wearing a leather glove) and give a few short bursts with the impact wrench. Threads on mine were rh (regular). Assemble in reverse order and hit it with your impact again. Perhaps some anti-sieze. The journeyman mechanics/posters may have better advice.....

Whatever you do, don't use pliers to hold the pulley and cause nicks. My 300D kept eating belts until I replaced the pulley.
