Hi all, I have a set elevation-azimuth Kempro KR-5600B, for some time, the azimuth rotor broke down to me, namely the internal ring gear, is a very common part is the same for several models kempro, Yaesu and daiwa. The ring gear is marked as 7501-005 http://www.ure.es/media/kunena/attachments/8171/daiwadr7500engranajes.jpg Any help to locate part is welcome. 73's Luis EC4TR
