In line with Mike's comment concerning the ball bearings; after being in the
elements for 30 years, you most likely will find the ball bearings in pretty
bad shape. A new set is not going to set you back an "arm and a leg"; you
might well find they need replacing too. My personal experience in over
hauling rotors is to remove and replace anything that at all looks like it
is worn. You want the rotor to be in tip top shape when you lug it up to
the top of the tower and re-install it!!

Don't forget the MOST important piece of rebuild equipment, a shallow
cardboard box to catch the ball bearings that will fall out when you crack
apart the 2 halves of the housing.
