Re: Need help reassembling a Sonora

I'm assumimg as you haven't pulled the motor down, it needs to have all the old lubrication removed & replaced, especially the grease in the spring barrels. The grease in the barrels will dry up over time, and prevent the motor operating properly due to friction.
Also you need to make sure the tonearm moves freely in all directions and is lubricated.
Once that's all done, if you are still having problems, you may need to look at replacement main springs because they can get tied if they've had a lot of use.
Once operating properly, those motors shouldn't have any problem playing a 10" record from any era, provided the disc is in reasonable condition & a new steel needle is used every time.
