It was discovered that between around 2008 and March 2017, there were inconsistencies in the press-fit force values of the machines used to press axles into wheels, and that wheelsets were being used with press-fit force values outside the specified range. Moreover, in March 2017, it was discovered that between 2008 and March 2017, press-fit force values outside the specified range had been altered to appear within the accepted range, and they were immediately corrected to the values output by the machine. Going forward, the work processes for wheelset assembly work will be reviewed and strictly managed.
