Statements from works dedicated to computation of mobile machines in variable operational environment and determination of vehicle load modes and lives of its units regarding the concepts concerning loading modes and their use for comparative estimations of life are developed. The problem of an estimation of units and aggregates lives in case of the absence of data for detailed life computation is considered. It is suggested that the life estimation should be produced by computing the extent of damage at characteristic points of mechanical system of the investigated machine and comparison of results with similarly received data from machinesanalogues. The technique is demonstrated by example of the life estimation of transmission ZF 6S850 under its use in vehicles MAZ-447131, DAF FAN LF55 21 tLHD and MAN TGL 8.180 7.5 Tonne 4x2 BB Tipper.
