FIELD: machine building.
SUBSTANCE: value of diagnosed parameter is measured at movement of actuating element of non-loaded and warmed loaded systems; volume efficiency coefficient is determined; its value is compared to maximum allowable one and technical state of pistons seals of hydraulic cylinders of hinges system is evaluated as per comparison results; as diagnosed parameter there measured is steady-state negative pressure in free cavity of hydraulic tank isolated from atmosphere for the test period.
EFFECT: simpler test process.
