[amsat-bb] Re: Need help dismantling KR-500

[i8cvs]

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
proceed.

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.
