Tony -
Unless you have access to a local machine shop and machinist, your only source for these Japanese manufactured parts is Yaesu USA. SOME of the KR-500 parts may be identical (common) to the current production Yaesu G-550 elevation rotator. Yaesu purchased the Kenpro Company which originated these designs. The individual azimuth and elevation rotators were KR-400 and KR-500. Later came the KR-5400, the KR-5400-A/B and the KR-5600-A/B. [i]After the purchase, Yaesu eventually changed these prefix designations to "G" from the earlier "KR". DIY REPAIR SITES for the KenPro / Yaesu Rotators, Courtesy of the previous KenPro/Yaesu queries from QRZ and AMSAT-BB reflector (archives) Henk, PA3GUO (Netherlands) described the repair and cleaning of the KR400 and KR500 rotators (Photos). http://www.pa3guo.com/ KENPRO-YAESU ELEVATION ROTATOR MAINTENANCE This is a useful collection of articles compiled by longtime AMSAT member Ron Long W8GUS. Common faults of the KR-500 series elevation rotator and its derivatives are described. Instructions, hints and tips for disassembly, cleaning, and rebuild are included.
