The method of positioning the clutch pressure plate is disclosed. The invention relates to a positioning method of a pressure plate of a clutch of a locomotive with respect to a reaction disc of the clutch. The clutch is a normally-opened type. The positioning method can be used to detect the worn state after a certain time of operation, for example the detection of the worn station of the friction disc, or the positioning condition of the pressure of the clutch after being assembled with different assemblies with respect to the reaction disc.
