• The duration of the launch of the power plant is checked taking into account the work of the cylinder-piston group and the gas distribution mechanism.
• The duration of the engine start is noted and the pressure in the lines of the lubricating, cooling and auxiliary systems is checked.

Addition

In the maintenance of the MTZ-80 tractor of the third degree, several more nuances are taken into account, namely:

• Checking the performance of the multi-mode controller. This indicator is checked for minimum, marginal and other indicators. This list includes the pressure that the fuel booster pump develops, the duration of the rotor rotation, and taking into account the performance of these mechanisms after the engine stops.
• Control and adjustment of the regulatory relay is carried out.
• The state of insulating comparisons of electrical wiring with the restoration of damaged sections is investigated.

Further technical maintenance of Belarus tractors and their analogues provides for a number of procedures:

• Checking the information of control devices for compliance with the standard. If this indicator does not correspond to the required parameter, it must be repaired or replaced.
• Change the filters on the fuel treatment pipe.
• Check the tightness of the pneumatic system.
• Diagnostics (without disassembly) of bearings, if necessary, adjust the clearances in the nodes of the driving and accompanying gears.
• Inspect and determine the wear according to the seat density of the flange driveshafts.
• Among other works on the indicated maintenance, tire inspection, flushing of the engine cooling system, power control and fuel consumption in hours, testing of the main units for operability in motion are carried out.

Seasonal Inspections

Maintenance of tractors largely depends on operating conditions, including climatic conditions.

In the autumn-winter period pay attention to the following points:

• Providing charge of the cooling system with refrigerant that is not subject to freezing.
• The work of an autonomous heater and the installation of insulation covers.
• Replacing the summer categories of oil with winter analogues, in accordance with the manufacturer's recommendations.
• Deactivation of the radiator of the diesel engine lubrication unit.
• Setting in the winter position ("Z") the adjusting screw of the seasonal controller of the machine.
• The technology of tractor maintenance in winter involves adjusting the electrolyte density in batteries to the appropriate standard.
• Check the working condition of devices aimed at facilitating the start of the starter.
• Check the tightness of the cooling unit, the integrity of the insulation, the current supply from the generator, heating the workplace (cab) and the efficiency of the fuses.

Spring and summer

Maintenance of the MTZ-82 tractor and similar machines at this time should also be carried out regularly. The list of work performed includes:

• Dismantling of insulation covers.
• Activation of the radiator system for lubricating the power unit.
• Disconnection of some units from the cooler of an autonomous heater.
• Installation of the adjusting screw of the relay type in position “L” (summer).
• The density of the electrolyte composition in the batteries is brought to the summer norm.
• Descale the cooling unit, if necessary.
• Fill the fuel part with fuel, the characteristics of which correspond to summer brands.

Also, the organization of tractor maintenance at this time involves checking the cooling system for maximum cooling capacity of the radiator. This takes into account the presence of grease on the rubbing elements, as well as the integrity of the electrical wiring and its associated elements. Check the response current of the regulatory relay. It is noteworthy that seasonal maintenance of the MTZ tractor can be excluded if it is operated in the southern climatic region.

Special Terms of Use

In certain cases, refueling and oil are closed. It is worth noting that the nuances of operating this equipment in desert and steppe conditions are as follows:

• Every shift is an oil change in the crankcase of the air purifier.
• If necessary, the central air pipe is cleaned.
• In the same mode, check the electrolyte level, supplement the tank with the required amount of distilled water.
• During maintenance of a wheeled tractor, the TO-1 performs oil change in a diesel engine through an express nozzle, and the track tension is regulated on tracked counterparts.
• TO-2 includes manipulations to flush the fuel tank, followed by refueling it completely at the end of the shift.

Condensate is also drained from pneumatic cylinders, the system is charged with a special non-freezing liquid, which serves as a kind of catalyst to neutralize the temperature conflict.

On stony ground, the design and maintenance of tractors is somewhat different from previous options. Among the features noted:

• Monthly check for deformation in the running gear and the protective part of the hulls, fillings of blocks and units of equipment.
• The fastenings of the drain plugs of the crankcase of the motor are checked, and similar parameters on both axles are taken into account. Detected malfunctions can only be resolved by replacing the part.

Interesting Facts

The device and maintenance of tractors that are operated in high mountain massifs and similar climatic conditions have slightly changed parameters. Consequently, tractor maintenance systems in such regions differ from similar systems in other climatic zones.

The features of TO include:

• Given the high altitude conditions, for the cyclical supply of fuel and increase the performance of the fuel pump, the operation of the entire unit is optimized taking into account the manufacturer's recommendations on the possibility of using the machine on a meter above sea level.
• When carrying out maintenance of the tractor, focused on functioning on marshy and unstable soils, an additional monthly check is carried out for work with mounted attachments that are focused on cultivating the corresponding soil.
• Such machines undergo monthly inspections in terms of cleaning the external surface of dirt.
• The degree of contamination of the lubrication and cooling systems is taken into account.
• When working in the forest take into account the cleaning of the machine from felling residues.
• After operating the equipment in wetlands or other difficult areas, check for the presence of water in the nodes of the power transmission and the running system. If water or condensation is detected in these compartments, the oil must be replaced.

Diagnostics

During maintenance of tractors and vehicles of a similar category, the following is checked in all cases:

• The condition of the crank assembly of the power unit.
• Cylinder piston group.
• Power train and trigger configuration.
• The performance of the main clutch with rotary clutch and bearing blocks.
• Status of steering, chassis, oil pump, PTO drive and gearbox.

What gives TO?

Maintenance is based on tractor care. These manipulations make it possible to regularly check the performance parameters of the equipment. At the same time, much attention is paid to the lubrication and tightening of the fasteners, which directly affects the safety and duration of operation.

Proper and timely maintenance provides the prerequisites for stable high-performance operation of machines and units based on them, the consumption of fuels and lubricants is reduced, tractor downtime is reduced, and the cost of their repair is reduced. If you follow the instructions of the factory instructions, which for the most part were approved back in the fifties of the last century, maintenance should be carried out on each shift, monthly and after a certain number of working hours. In this case, the types and design features of the equipment are taken into account.

As a rule, the frequency of servicing machines and tractors is technically taken into account after working out a specific number of arable or construction hours. The whole process is governed by regulations and standards developed by advanced machine operators in conjunction with scientists. This is very important, because when developing a maintenance plan, it is worth considering many factors, including climatic features, fuel costs, type of engine and other tactical and technical characteristics.

Total

The maintenance procedure for tractors and other agricultural machinery allows us to ensure the condition of the machines, improves their productivity, while focusing on energy savings and improving reliability. Despite the fact that the existing system is somewhat outdated, it takes into account a number of important factors, distributing the tractor check both before operational break-in and after prolonged use.
