I have and older L275 with a L1730 Loader frame (The one made by Full Vision, INC. model #121 Serial # 31013) and I am looking for the tilt cylinder repacking kit. The Kubota 70050-00764 kit is not the correct kit. Does anyone know where I can find a rebuild kit? Or can I replace the old cylinders with the newer Kubota L1730 cylinders?
