The nice thing about this hobby is that parts are normally available for most brands of talking machines unlike most modern audio products which are designed to be thrown out once they break or wear out.
Sonora was a popular off-brand during the teens and into the mid-1920s, and the phonographs are generally well made. If you do decide to clean and service the motor, about the only thing to be careful about would be re-greasing the mainsprings, but you can always remove the spring barrels and ship them to a repair shop, if need be. (This would probably cost about $100, unlike a thorough motor take-down and cleaning, which can run into the hundreds of dollars.) If you want to do the job yourself, I'd strongly advise that you take some detailed photographs of the motor and save them to refer back to.
I'm glad it came with the original owner's manual. That will show you the proper way to position the reproducer to play the different types of records available at the time your phonograph was produced, though most of what you'd come across today would probably be standard "78s," which are normally played with steel needles. The special sapphire ball stylus required to play Pathe' vertical cut records is available today and sold by a few repair shops, though I don't know about the diamond tip stylus for Edison Diamond Disc records.
In any event, keep us posted on your progress.
