Hmmm, I submitted this post last night and it seems to have disappeared.

Get a pump oiler. Fill it with ARO. Attach it to the breather and pump the crankcase FULL of oil. Clamp off the breather. Turn the motor over by hand several times. This will pump the oil past the rear bearing. Unclamp the breather and turn the motor over until the breather quits spitting oil. DONE.
