Hi Richard, G3RWL

If you have the original manual of the elevation rotator KR-500 there
is a clear mechanical drawing inside showing bearings ,ball retainers,
gears and all shaft in line so that it is very easy to understand how

If you don't hown the above drawing I can send to you a scanned copy
of it.

You did already the most critical job to remove the eigth screws fastening
both alves of the rotator HI....HI !

About the grease I have used the molibdene black grease for differential
gears on truks.
