The article “Proposal of Corrective Maintenance Actions for the Generator Set (GMG) STEMAC DS8528 at the Soyo/Zaire Polytechnic Institute” addresses the need to implement corrective maintenance practices to ensure the reliability and efficiency of the generator set used by the institution. The study begins with the observation of recurring equipment failures, which compromise the continuity of electricity supply in educational and laboratory environments. The research describes the operational history of the STEMAC DS8528 GMG, identifying the main technical problems such as component wear, lubrication system failures, overheating, and irregularities in the control system. The methodology applied includes technical inspections, document analysis, and interviews with operators, allowing the mapping of failure causes and the proposal of practical solutions. Among the suggested actions are: periodic replacement of critical parts, reinforcement of lubrication procedures, calibration of monitoring systems, training of responsible technicians, and the creation of a systematic corrective maintenance plan. The article emphasizes that such measures not only extend the generator’s lifespan but also reduce operational costs and prevent interruptions in energy supply. It is concluded that the adoption of a structured corrective maintenance plan is essential to ensure the reliability of the GMG, contributing to the proper functioning of pedagogical and laboratory activities at the Soyo Polytechnic Institute. The study serves as a reference for other institutions that rely on generator sets in regions with unstable energy supply.
