Thanks james 1549, That settles the idea that the bearings are sealed and cannot be packed. I'm thinking that with the lithium grease we have today that maybe there is no regular service interval on the bearings and only needs to be done when replacing the rotor.

BTW where did you find the service manual ? Is it somewhere on our site or did you get it somewhere else that I could access ? It would save a lot of questions on my part.
