First, the field data of fuel valve replacement of a marine diesel engine were dealt with by Hashimoto et al, from statistical viewpoints. One of their main results was that in the case of maintenance of diesel engine, the fuel valve replacement was the most important one. Next, by the authors the secular change of a fuel valve and an exhaust valve was analyzed by using the shape parameter m of the Weibull distribution. In this paper, MTBF and replacement distribution of the fuel valve were estimated from the field data of various ships from 1966 to 1977 through same technique as in the former paper. According to the results obtained, it is the most important result that the shape parameter m of the replacement distribution of the fuel valve ranges from about 0.7 to 1.5.
