Abstract

Clutch noise that occurs in the engine is a major cause of decreased efficiency of the engine assembly. This phenomenon has been there in such a long time in the production line, and has created a complex cause that requires a structured and systematic method in terms of handling this problem so that it can be reduced or even be eliminated. On the Problem identification, it is known that clutch noise is the result of non standard backlash. By the IPO diagram and fishbone diagram, all the non standard backlash factors are sorted into man, machine, method, and material. For the primary clutch, the value of CP = 0.02 and CPK = –0.31, indicates that the average is outside lower limit and upper limit therefore special attention must be addressed to improve it. For the secondary clutch, the value of CP = 0.22 and CPK = 0.302, which implies that the value within 0 – 1 that described the average is in between upper limit and lower limit, but there are some variance outside lower limit and upper limit. For crankcase, the value of CP = 0,79 and CPK = 1.2 signifies that the process is in control. The CPK value is greater than 1 shows that the process in in between lower limit and upper limit. DPMO target is 50,000 and the actual DPMO is 32,201 and after Lean Six Sigma was implemented, the value has been reduced to 5,487. Keywords: Lean Six Sigma, DMIC, CP, CPK, DPMO, IPO diagram and Fishbone diagram.
