Oster Electro-Blender 411

[paulg]

Here's the estate-sale find for today. This is an Oster Electro-Blender model 411.
We're interested if anyone knows anything about this unit; nothing was readily available on the internet.
Today we tried to remove the motor so we can scrub the housing. Unfortunately we cannot figure out how to disengage the motor from the coupling (that meets the bottom of the blender jar). Seems stuck. How do I get this apart?

Stud talk

Got the stud off.
The stud and spinner were threaded. Craftsman tools to the rescue!
Actually we bought a second Osterizer at the same sale for the jar. Used that one to learn how to disassemble the other. The "Galaxy 80" will go to its reward so that the Electro-Blender can live.
All housing parts are now getting spa treatment in the dishwasher while them electrical parts get serviced.
