Spare Parts for D-75 Tractor, Features of Their Technical Service

In cold weather, maintenance of the tractor DT-75 is carried out in a heated room, where the air temperature should not fall below + 5 * C. The vehicle should be inspected immediately after you have muffled the tractor while the units and assemblies are still warm.

During maintenance, inspect the tractor for leaks of fuel and lubricants. This is done in order to avoid oil getting into the brake drums, which, in turn, can provoke sticking of the shoes.

The tractor dt-75 should be filled with hot oil. Such spare parts for tractor DT-75 as air cleaners, oil and fuel filters, nozzles are washed in a special washing liquid, heated to a temperature of 35 ... 45 * С. The tool used during the inspection must be heated to the same temperature.

When servicing the cooling system, pay special attention to the pipelines and the condition of the drainage liquid, their connection densities. Then the system must check the circulation of the coolant. If the circulation is within normal limits, then on the warmed-up engine the temperature difference in the upper and lower parts of the radiator will not exceed 10 ... 12 * С.

Inspecting the power system, you need to insulate the fuel, the fuel filter housing, the fuel pump and the fuel tank. In winter, it is necessary to clean the fuel of water and mechanical impurities. Diesel fuel should be defended from four to ten days.

The next thing to check is the lubrication system, which is thoroughly washed with the engine off. After every 60 hours of operation of the DT-75 tractor during winter operation, inspect the condition of the oil filters, which must also be washed.

Transmission and chassis - these are parts for the tractor , for trouble-free operation of which it is important to choose the appropriate lubricants.

As for crawler tractors, in order to avoid breakage of caterpillars their tension should be slightly weakened, in contrast to the summer work period.

The functioning of the hydraulic system depends mainly on the viscosity of the working fluid.

To warm the oil at low air temperatures, the pump is switched on for a short time for idling, approximately 3 ... 4 minutes, without resorting to the handles of the distributor. Then one of the handles is moved to the "Lift" position, while holding it for 1 ... 2 minutes. After the lifting of the suspended machine. All these actions should be repeated until the oil temperature reaches 20 ... 30 * C.
