This is the only part in this alternator that I actually replaced. The Westerbeke diesel engine this alternator came off of has 2800 hours on it and this alternator was still in perfect working condition. I only replaced the front bearing because it sees the most wear.


If you are wondering why this alternator is so clean it's because I cheated and had bead blasted the alternator. I had already taken it apart but forgot to photograph it the first time.
