Time to get this thing done so, here's how I pulled the gears on the crank and replaced the #3 main bearing.
First I drilled a countersink into the top of an 8 mm bolt to protect the threads in the nose of the crank thtat secures the fan hub. Attached image(s)

Drop the gear on, line up the slot with the Woodruff key and give it a little persuasion. This one just took a light tap.
