I had my alternator rebuilt by a local auto electric shop. The guy took forever so he delivered it to my house as a courtesy. I immediately noticed that it didn't have the correct pulley with the four notches. It appears to be very close in size but I don't know the diameter of the original.
The day after he delivered it I left on a 3 week trip and told him I would connect with him when I got back. Now I can't reach the guy and am wondering if I can use the one he installed. Two questions: 1. Could someone kindly measure the diameter and let me know what it is? 2. If the diameter is slightly different will charging be affected? The belt seems to fit fine in the channel. Thanks in advance for your help. This is the last step before the engine goes back in. Jack |

Thanks very much Dave. Very helpful.
Maybe someone has access to one in the garage and put a tape measure on it. Jack |

Thanks very much Dave. Very helpful. Maybe someone has access to one in the garage and put a tape measure on it. Jack Just happen to be at the same point as you and I do have the pulley. It measures 3.630" OD on the face that has the 4 slots. The other side is 3.603". The "V" groove root is approx 2.63". I say an estimate because I can't fully get my calipers fully seated into the groove. |
