After getting my sprocket removed, I realized that I didn't have the correct tool to get the torque wrench on the nut. After the fact, I learned there is a special wrench you attach to your wrench to get the proper angle. The spokes and disk make it impossible to get a straight shot with torque wrench. FYI. I ended up doing it with red loctite and box wrench. I hope I got them tight enough!
