Well I could do that, but it wouldn't be any fun.These old CBs needs every electrolytic capacitor replaced. Frankly, I would rather buy a trouble free new President McKinley CB and call it a day.
I have bought entire replacement motors on ebay. They are the KitKat clock motorsFound 3mm plastic screws on fleabay. The thread pitch is 0.1mm.
Good luck with the motor. They have so little torque that it's hard to judge how well you have freed it up with cleaning and/or lubrication. Takes really low-viscosity oil, I was told.
Never had the patience to rehab those clock motors after the first few tries.
