Radio: GE R-2990A Sun gear for the tuning planetary gear set. Print either the full or short version. The two versions differ by 0.5mm in collar length. Print with care. The centre hole is undersized and requires careful reaming out to 4.0mm before assembly. This sun gear will then be pressed onto a knurled section of the tuning shaft, lubricated with suitable grease. Installation instructions recommend facing the collar upwards. If the gear binds when reinstalling the circlip, use the short version.
