The objective of every maintenance department is to anticipate repairs and initiate activities that prevent mechanical failures. Manufacturing firms perform various preventive maintenance (PM) activities at specified intervals to achieve this objective. Some intervals evolve from manufacturers’ specifications and industry experiences; others are simply handed down over time with no real understanding of where they came from. Effective preventive maintenance inspection (PMIs) also ensures that equipments (diesel power generators) reach their useful service life. This study examines the various problem and faults associated with diesel generators in service. The approach to this study consisted of a survey questionnaire, literature review, and interviews conducted with two manufacturing firm as case studies. The survey questionnaire, posted on the maintenance personnel of these firms, produced a total of 48 respondents. A review of the survey responses confirmed that personnel of both firms are equally represented. The sample is random; therefore, it is representative. Model application employing Likert scale and Opinion Discrimination Analysis (ODA) reveal the influential faults that(PMIs) teams should look out for when carrying out PM programs to help reduce the in-service mechanical breakdowns that occur in the operation of diesel power generators.
