The article analyzed the methods and technologies of restoration the camshaft of internal combustionengine, their advantages and disadvantages , as well as working conditions couple camshaft cam − lifter.Found, that there is currently no rational way of recovery, which combined have a high performance, costeffectiveness, as well as high wear resistance of the camshaft cam and lifter.Requirement to ensure high wear couples camshaft cam - lifter is of particular relevance due to thefact that the currently increasing engine power, by increasing the speed of the crankshaft.In this regard, it is urgent search for new universal recovery technologies camshafts internalcombustion engines, that can increase the service life of the reduced camshaft, to ensure environmentalcleanliness recovery process, reduce the cost and complexity of repairs, ensure high durability couplescamshafts cam − lifter.
