For legacy ICC AIC without integral controls effective alternative methods for determining the status and necessary work, repair work to identify, and most importantly - the causes of the high abrasive wear of friction parts.  So on the spot oil [1] on filter paper (figure 1) reveals: - the degree of loss of working and cleaning properties of oil by reducing the diameter of the spot, and hence the risk of coking of the cylinder-piston group and accelerated wear of all internal combustion en-gines,  - pollution of oil and the pace of abrasive wear the dark spot - water oil on the water leads to the edges of the spot, and hence the danger of marriage oil and emergen-cy units.  Analyze sediment in oil centrifuge and accidental deterioration see particles of metals [1]. Reveal the dynamics of waste oil to the fuel consumption of internal combustion engines, and the monthly growth of 0.5 % - the sign of his fast aging. To prevent increased wear of engine more control of oil, pressurized intake tract, close from pollu-tion motors in General, enter into ice magnetic tube, and in maclaverty magnesium chips. Weekly poured 50 ml sludge crankcase oils for the inspection and removal of water. Most are organoleptic diagnosis quantitative characteristics of state of the units.  Since 1990 injected into the crankcase oil preventive, and instead of repair - the repair trains. First, for example, Energy 3000 form on the friction surfaces of protective anti-friction, anti-wear nanolayers, and the second - anti-friction, anti-wear, oleophilic coating thickness 1-10 microns (up to 650 mm nanodiamond tribalistika KARAT-5). Use and grease POLITERM-multipurpose with ribosomami. Break refurbished units tested tribalistas Eco-Universal Oil-Package, Micro-Ceramic Universal Oil-by Wagner. All this noticeably increases dormantly, post-repair and complete resource, and a residual resource of cylinder groups on indicators of the residual vacuum and compression in cylinders devices sintering shop, announcing the library determine Express [1].   Thus, the main task of maintenance of machine-tractor Park on elimination of abnormal wear of units of the machines  and to increase their resource is solved.
