The article discusses issues related to the application of diagnostic methods for the process of run-ningin of internal combustion engines of trucks. Diagnostic signs have been investigated and substan-tiated to determine the actual duration of runningin of the engine parts of the SITRAK C7H mainline tractor, the most pronounced process after major repairs. Unfavorable combinations of influencing factors have been identified that may make it difficult to run-in due to serious damage to the friction surfaces. Patterns of changes in diagnostic parameters have been established depending on the inten-sity of the processes of runningin of rubbing surfaces. The authors substantiate the relevance of moni-toring the condition of rubbing surfaces during runningin, and propose a comprehensive test method for various engine operating modes and remote monitoring of diagnostic parameters.
