Sunbeam 2484 Beaters won't stay engaged.

In taking apart my same beater, I'm trying to figure out the alignment of the spring which provides the tension so that the beaters won't fall out. I'd assume that your spring has mis-aligned. You need to take it apart (3 Philips screws), and carefully pull the assembly apart. I'll bet your spring falls out like mine did. I'm trying to find a schematic from Sunbeam to see how the spring should align.
