Marine machine sets with combustion engine have to fulfill requirements of safety, quality and efficiency. It is reflected in all elements of maintenance: conservation, inspections and repairs. Main points of interests are repair technologies and all types of condition identification: estimation of free element quality, elements before and after repair, estimation of assembling quality and diagnosis. In case of marine engines does not exist any offer of system of identification, which fulfill requirements, especially safety requirements. There exist necessary to analyze, development and systemize methods of identification and generate a system of identification for machine set with machines with piston – crank mechanism. In the papers will be presented uniform classification of deviations include deviations of free element, deviations of elements built in set/machine set and diagnostic symptoms. There will be presented, specific for ship machine sets with engine with crank-piston mechanism, symptoms and deviations, and relations between them: - it will be presented model based on measured spectrum of axial vibrations and measured spectrum of loads on engine cylinders. This model was generated to condition monitoring of crank shaft position; - it will be shown deviations and symptoms of tribological junction condition and diagnostic models based on defined and measurable deviations and vibration symptoms. Generated model will allow to monitoring the condition of connecting-rod head bearing, crosshead bearing, connecting-rod big end bearing and main bearings.
