Abstract: A method and an apparatus for notifying an error of an axial direction of a crankshaft are provided to sense an axial gap of the crankshaft caused by wear of a thrust washer. An apparatus for alarming an error of an axial direction of a crankshaft includes a sensing tip(10) installed at a rotating body(30) on the crankshaft. A sensor(20) is positioned on a fixed body adjacent to the rotating body(30), and outputs a predetermined signal by sensing the sensing tip(10). An ECU outputs an alarm signal when a number of rotation of an engine inputted from the sensor(20) is not identical to that of the conventional engine. A display device displays the alarm signal outputted from the ECU at a cluster.
