Hello Everyone! We were lucky enough to win a nice Victor III at an auction last week. When we got it home it was a typical unrestored machine. Covered in old crusty grease and one governor weight had a broken spring. We took it all apart, cleaned each part thoroughly and ordered and received three new governor springs. We then removed, cleaned, and re-greased both springs and then put it all together again. It looks good but there is a loud knocking sound coming from the drive gear. We have experience with Edison cylinder machines and Victrolas but this is our first outside horn Victor. On closer inspection, it seems the drive gear is disengaging the governor worm gear and then slipping into place causing a loud knock. Here is what we have tried.
1. Adjusted the governor back and forth to mate the gears better. 2. Lubricated the worm gear and drive gear with grease, then oil, then grease and oil. 3. Flipped the drive gear upside down. (as shown in video) 4. Made sure all parts fit properly and move freely. 5. Made sure that no parts of the governor are hitting anything when moving. None of this has worked so here we are asking for anyone's advice. The brass drive gear does not look worn or warped although it sounds like it is. Any ideas would be greatly appreciated! Please see video below to hear it knocking. Please remember that all lubrication is missing in the video to better show the gears and the dive gear is indeed turned upside down but we get the exact same result when it is right side up. http://www.youtube.com/watch?v=AZAOHqKQ1K8 Thank you, Melissa and Nick _______________________________________________ Phono-L mailing list http://phono-l.org
