Abstract: The article proposes a method of diagnostics of the actual technical condition of the motor-wheel gear of pit dump trucks. It allows monitoring the depreciation of the bearing assemblies, and also to control the parameters of achieving the maximum permissible meanings. Application of this method allows to prevent the refusal of a reducer of the motor wheel of a dump truck and to carry out scheduled preventive measures for the worn-out bearing replacement. Through this method, the motor-wheel gear unit will not operate with the gaps in an allowable excess. It will prevent its failure and will contribute to the following qualitative improvements: operational control of the state of career dump; constant monitoring of the condition of the gear unit during its operation; longer intervals between scheduled maintenance and repair; reducing unplanned downtime of the equipment; a decrease of the current repair costs; career dump protection from accidents (in case of sudden failure of motor-wheel gear); savings on the purchase of new parts and repair work as a result of preventive measures.

Key words: diagnostics depreciation pit dump (career )truck reduction gear bearing
