Analysis the measurement quality system of clearence tappet using measurement system analysis on motorcycle manufacturing company

A motorcycle manufacturing company on the K56S engine has a symptom that often occurs called noise tappet. The observations found that Symptom was caused by clearence or tappet gap that was not in accordance with the specified specifications. The gap measurement system uses filller which usually relies on the experience and feeling of the operator, so it is possible to produce an unsuitable gap measurement. This research will evaluate the measurement system of clearence tappet using Measurement system analysis (MSA) which includes stability, bias, linearity, repeatability & reproducibility. Based on data processing known that the measurement system has a stable process with a linearity level of 2.6% is acceptable. The measurement system has a biased problem with an average bias value of 0.054 mm (not acceptable) and from repeatability & reproducibility with a GRR% of ANOVA method of 49.98% that exceeds the acceptance criteria.
