Description
Radio: GE R-2990A
Sun gear for the tuning planetary gear set.
Print either the full or short version. There is a 0.5mm difference in collar lengths.
Print carefully. Centre hole is undersized and will need careful reaming out to 4.0mm. This is then press fit onto the tuning shaft on a knurled section. Lubricate with appropriate grease.
Recommend to install with collar facing up. Use the short version if you find that the gear binds when re-installing the circlip.
