Ring 151.37.540 is installed in the transfer case of HTZ tractors on the pump drive shaft and serves for correct positioning and separation of two bearings 206.8338. This design ensures correct operation of the bearings, reduces the risk of their displacement and overheating, and also increases the reliability of the entire assembly.
The part is made of durable steel with high wear resistance, which allows it to withstand constant loads and exposure to oil inside the transfer case. The ring is one of the small but important elements of the transmission, which directly affects the service life of the bearings and the stability of the pump drive.
It is used in transmissions of wheeled tractors HTZ-17221, T-150, T-156 and other models of the HTZ family.
