Title:
SEAL,OIL (KU-TD35051390)
Description:
The Kubota SEAL, OIL (KU-TD35051390) is a genuine transmission oil seal designed to prevent hydraulic or transmission oil from escaping around the HST input shaft. It sits within the HST input-shaft assembly and forms a sealing barrier around the rotating shaft, helping retain lubricant while preventing contaminants from entering the transmission. The seal works alongside the input shaft, bearings and surrounding transmission housing to maintain the correct operating environment for the hydrostatic transmission. Kubota parts diagrams identify TD350-51390 specifically as SEAL, OIL within the HST input-shaft component assembly.
