In article is offered methodology of estimation the tightness of agricultural tractors hydraulic distributors’ precision elements by pneumatic pressing. Presented analysis the reasons of lose an elasticity of the relief valves springs, the boosters and the safety valves springs. The proposed methodology for assessing the tightness of distributor by pneumatic pressure, allows to obtain quantitative estimates of the interface resource, takes into account changes in the dynamic viscosity and density of air and oil. According to the developed method of disrepair search, the several estimations are taken as indicators of tightness, such as good, satisfactory, unsatisfactory. Preliminary results are presented, indicating not only the sensitivity of the ordered method, but also the presence of a correlation between the technical condition of the various valve interfaces. Given method allows to get the quantitative estimations of interfacing resource, it is more simple in realization, is less labour - consuming, it does not require expensive equipment, also possess sufficient informing and exacting.
