I reassembled the quill and spindle. It went pretty smoothly. I packed the tapered roller bearings with the Kluber grease trying to fill 50% of the available volume.
The new bearing in the top of the spindle sits about 1mm past the top of the quill. I'm using the washer that was just beneath the c-nuts and it seems to fit about perfect.
Here is the assembly back in the head.
Don't forget to put the rubber ring back on at the bottom of the quill like I did or you'll have to take the whole damn thing apart again and redo...
Here is a photo of what I'm calling the 'magic screw'. It took me a long time to find this little jerk to remove the spindle. The preparation guide didn't illustrate this thing well enough.
The only real tough part was getting the spring back on and tensioned correctly. Here's a tip: use a large set of circlip pliers to grip the spring cage by those 2 holes. Then you can wind the spring back to your liking with little issues. First I tried using big pliers like the preparation guide shows, but that wasn't working well.
The spindle is much harder to turn by hand now then it was. I may have pre-tensioned it more then the factory did. Also, the grease I'm using is much thicker than what was in there before. It might settle and spread a good bit too. It is nice and smooth though, so I'm going to leave it for now and see how the motor handles it. I can back off the pre-tensioning if I need to. I think I'd rather have the motor work harder and have less vibration in general though.
When I first turned it on, there was a nasty noise. I'm fairly sure it's in one of the gears. I think its either the spline gear or the 2 metal main drive gears on the top of the head. I'll pull the spindle assembly tonight and just run the gears to see if that's where the sound is coming from. The main drive gear that powers the spline might have taken a bang during disassembly. Hopefully I'll be able to find a little dent and file it out.
I'll probably post a list of the parts and specialty tools I used to do this bearing change next time. In case anyone else is thinking about it.
