Abstract：In order to improve the turbocharger′s assembly quality of S company , an improvement is made on the traditional fishbone diagram , based on the concept of total quality management , in which two impor-tant factors, i.e.design and inspect , are added.The improved fishbone diagram method is then used to analyze the floating bearing leakage accident that happened in turbocharger assembly line of S company , and identify the causes and key reasons .During the whole process , the PDCA cycle management theory is utilized to formulate corresponding measures and consolidate the results .From early 2012 to the end of 2013 , the leakage accidents have decreased from three to zero , which means that the quality target is reached .
