Special nut 151.72.226 is a castle nut for a cotter pin, ensuring reliable fixation of critical components. Four units are installed on the tractor: two are used in the steering, two in the axles.
In the axles, the nut secures the drive gear 150.38.103-2, which is part of the planetary gearbox. Thanks to the crown design and the installation of a cotter pin, 100% fixation is ensured without the risk of self-unwinding under high loads.
In the steering, the nut is used together with pins 151.40.278, which are part of the rotary hydraulic cylinders. Secure fixation of these elements is critical to the safety and stable operation of the steering system.
Nut 151.72.226 is made of durable alloy steel, withstands shock and vibration loads, meets HTZ factory standards and is suitable for both original units and high-quality similar parts.
Used on HTZ tractors: T-150, T-151, T-156, HTZ-17221, HTZ-242, HTZ-248 and other models with similar axles and steering cylinders.
