As far as rebuilding the bottom end of an E motor, there are TWO different E motors. The difference as I have come to understand, is in the right hand side spacer plate. There's a single piece and a two piece. I only have experience with the single piece.
If you have the single piece, I have every bearing and seal number listed in one of 'Fixer's threads.
Here's a list of all the bearing, seals and Orings and their corresponding locations & dimensions.

If you know what you're looking at, post #45 shows the right hand side. As far any difference between the two different E motors, I cannot say. They may take the exact same parts. Again, I do not know.
