Here's the solution. The spring controls the beater eject button. The spring is mounted on the metal shaft and is oriented so that the straight side of the spring rests along the white plastic part adjacent to the shaft, and the curved side of the spring points outward and downward so that it will rest against the case when the unit is reassembled.

Try light oil to the button. It might work.

Beaters touching can be dangerous as much as not holding in place. Check if the teeth in the beater and the machine are of the same brand and and construction. Make sure you do not use any other mix and match parts because of danger.

For mixmaster junior, but should be relevent to many old sunbeams:

That's not the power cord going to the speed switch. You don't need to get those screws off.
To replace the cord:
Cut the old power cord near where it enters the blender.
remove the two front screws, pull off front housing.
remove 1/4" nuts found in recesses of exposed front plate.
pull speed handle out far enough to get a screwdriver under exposed front plate, and pry gently. It'll come off as it's a friction fit.
cooling fan blade is now visible, you need to remove it.
pry up gently on the teeth attaching it to the motor shaft.
Work your way around the 4 sets of teeth, it'll come off. Don't lose the two washers.
unscrew the electrical contacts.
take off the speednuts holding the brush assembly in place.
gently pull up on the brush assembly with a needle nose, until it comes out.
now remove the screws holding the motor coils in place. They're the same ones the speednuts attached to, and have hex heads you can get at with a needlenose.
once those are out, pull on the motor coils gentle, and wiggle them out of the housing.
You'll see the stub of the old power cord at the back of it.
Get a round replacement wire of the right diameter, thread it through the cord hole in the blender, and connect it up to the coils.
-I had to drill the power cord hole 1/16" larger than it was to get a modern cord to fit through it.
On the stub of the old cord, you'll see a metal ring which serves to anchor the cord in blender body. remove it (screwdriver + needlenose and pry), and attach to new cord at the righ position.
Put everything back together, being careful not to bust the carbon brushes.
Congrats, you now have a functional blender with a cord that won't try to electrocute you.

The bowl locks in with notches in the base. Just turn the entire bowl to unlatch it. Good luck.

If the motors had burnt out then the winding can be redone if you can get this job to a winding shop.
Other wise the motor and assmebly can be ordered from a Sunbeam service outlet. try and see if you re able to source a motor assembly from a damaged/scrapped set with a mechanical defect.
