Based on the results of the analysis, evaluation of basic types of gas-distribution mechanism failures, including wear of the chain damper, has been done; critical parameters of this wear have been defined, which allowed proposing a theoretical model for calculation of dominating types of wear. Basic conditions of this model have been calculated for the scheme of contact of two cross cylinders, whose axis projections cross each other at a 90\u00ba-angle, one of the cylinders being stationary. Based on the obtained model, given the prescribed values of load, and friction path, calculation parameters of the model of steady wear, contact pressure in harness have been defined; the value of wear depending on friction path and coefficient of wear comparison for two adopted anti-friction materials (basic (\u0421\u041a\u041d-40 rubber) and newly-proposed (grafelon-20)) has been calculated. The results show that \u2018grafelon-20\u2019 material prevails over the basic material almost in 5.4 times in terms of wear resistance. Based on the calculations done, a technological scheme of production of laboratory samples for research of \u2018grafelon-20\u2019 material was tested and a technological process of production of damper plates was proposed. It envisages three basic operations: briquetting, pressing, and pasting of the produced plate to metal base. The author has provided a detailed description, characteristics, and some peculiarities of these operations, such as defining the temperature of heating while pressing, duration of heating, and the value of pressure needed.
