Effective use of machines largely depends on timely and high-quality maintenance and repair. Due to the increase in the volume of restoration of units and aggregates at specialized enterprises, an opportunity was created in the workshops of farms and collective farms to more widely apply the aggregate method of restoration and repair. Improving the organization of centralized restoration of damaged parts makes it possible to restore tens of millions hryvnas worth of parts in a year. The organization of centralized delivery of material and technical means to farms is applied using the services of equipping farms with the necessary equipment in assembled, adjusted and run-in form.
Increasing the level of concentration of repair production, deepening its specialization will allow to significantly improve the quality of repair, to bring the resource of repaired machines, tractors, combines and aggregates up to 80%.
Before repairing driven discs of clutches of tractors, cars, combines, to replace friction linings, it is necessary to carry out operations of drilling, riveting and knocking off old linings. These operations require a lot of labor and the use of additional tools, which leads to significant capital investments.
The paper proposes a device for cutting the fastenings of the friction linings of the driven clutch discs. Taking into account the conditions of agricultural enterprises, which have repair workshops, and the presence of vertical boring and milling machines, it is proposed to organize their use for the operation of removing worn friction linings.
For riveting of friction linings of driven clutch discs, the development of a hydraulic stand is proposed, which can be made from standard units in the workshops of agricultural enterprises. Using this stand will make it possible to increase labor productivity when performing this operation and reduce its time.
