Its been up on the mast 20+ years but still turns ok. I now have it off the mast and, before I sell it, I'd like to clean it up, replace the grease etc.
Loosening the screws has been quite a journey, strong wrench and lots of blowlamp. Before I finally open it up I recall that someone had put dismantling instructions online somewhere but I can't find them; grateful for a pointer and/or other tips. Also which grease to use (USA greases are not available here in the UK).

Here's a link to the G-5500 elevation rotor disassembly/assembly.
I believe the KR-500 is the same (or nearly so).

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.

Most important thing: Prepare for some ball bearings to fall out. If you are not prepared, some greasy ball bearings will roll around the kitchen floor. Very dangerous and makes an awful mess. Been there.
