Hydraulic nuts

The high pressure oil into the paddle and paddle cone between the propeller to open up, the use of hydraulic nut propeller pushed into the design position, remove the high pressure oil, propeller shrink tight on the shaft, the use of propeller and the friction between the torque transmission torque The When the propeller is removed, the propeller will fall from the propeller shaft by loosening the hydraulic nut and releasing the high pressure oil between the propeller and the propeller shaft. Features: Hydraulic nuts installed, the process of removing the propeller is not only simple but also to maintain the original surface with the accuracy, to avoid "Chung hit" disassembly caused by the accuracy of damage, re-use to be repaired, or even scrapped.
