I wrote up the procedure I used to replace the steering head bearings in this web page:
At this point, the project is turning around from disassembly to reassembly as I installed the steering stem with polished lower triple clamp and new top chrome dust cover in the recently powder coated frame. 🙂
Here are a few of the many pictures you will find in the web page write up.
