The article considers the issues of imported forest machines maintenance technology and knowledge management in the North- West of the Russian Federation. The paper proposes a structure of technological instruction to restore parts by welding and building up.
Basic requirements for the work-site arrangement are formulated. Theoretical statements are accompanied by calculated reliability assessment of forest machines. The assessment is based on the research of details durability of forest machinery John Deere 1010 and 1410. The research was carried out for four years and included 16 forest machines. The main objects of the research were details of processing equipment (manipulator), hydraulic system, and engine fuel system of forwarder John Deere 1010 D. The efficiency criteria of multicomponent reserve delivery of spare parts and consumables are formulated.
