The Flywheel Lock Nut is mounted on the threaded end of the crankshaft, which protrudes from the engine block. The flywheel itself slides onto the crankshaft and is positioned against a machined surface. The flywheel lock nut is then threaded onto the exposed threads of the crankshaft and tightened to a specified torque. This torque ensures a precise clamping force that holds the flywheel securely in place.Attributes:• Prevents flywheel from coming off crankshaft during engine operation• Withstand impact fatigue and abrasionApplications: The Flywheel Lock Nut secures the flywheel assembly on the crankshaft of an engine. It ensures a precise and stable connection that can withstand the significant rotational forces generated by the engine.
