In addition, at intervals of 2000 operating hours, the following is carried out: dismantling the fuel injection pump for complete qualified diagnostics and adjustment by fuel specialists at the stand, as well as checking and adjusting the pressure and quality of injection of the injectors. After 3000 operating hours, the starter is dismantled for complete diagnosis and repair.

Seasonal Maintenance

The transition from summer to winter is determined by the establishment of an average daily temperature below +5˚С and, conversely, the transition from winter to summer at temperatures above +5˚С.

Transition to winter

• Replace summer brands of oils with winter ones: in the diesel crankcase, in hydraulic unit housings, in the power steering, transmission housing, in the front drive unit housing, in the housings of the front drive wheel gearboxes, in the intermediate support, in the housings of the MTZ 82R final drives.
• Screw the generator seasonal voltage adjustment screw all the way to position “W” - Winter.
• Change the lubricant of the front wheel hubs of the MTZ 80.1/80.2 tractors.
• Adjust the wheel bearing clearance.
• Flush the diesel cooling system and fill it with antifreeze liquid.
• Clean the calibrated hole in the fitting of the electric torch preheater.
• Remove the FDA drive cardan shafts and check the axial play: in the mounting flanges of the transfer case, intermediate support and the drive gear of the FDA main drive. Eliminate all axial gaps by tightening.

Transition to summer

• Replace winter grades of oil with summer grades in the diesel crankcase and in the above listed component housings.
• Set the seasonal adjustment screw on the generator to the “L” position - summer.

Additional maintenance when operating the tractor under special conditions

Operation under special conditions includes work in low temperatures, deserts, swampy areas, high mountains and rocky areas. At the same time, the order of established maintenance activities is maintained with some additional operations or are carried out at more frequent intervals.

When working in dusty sandy areas at elevated temperatures.

• Refill fuel and oil in a closed manner.
• Change the oil in the air cleaner pan every third shift.
• During TO-1, additionally check the diesel oil for mechanical inclusions. If contamination is detected, perform a complete oil change.
• Check the cleanliness of the central pipe of the air cleaner. Wash the air filter every 20 hours of operation.
• Blow air or flush the radiator heat exchanger with water.
• During maintenance-2, wash the fuel tank cap.

Operation in low temperature conditions.

• Perform pre-heating to 20-30˚C.
• At the end of your shift, leave your fuel tanks fully filled.
• At -30˚C, fill with arctic diesel fuel and antifreeze into the cooling system.
• Drain the condensate from the pneumatic system receiver every shift.

When working in high altitude conditions.

For normal engine operation in conditions of reduced oxygen in the air, adjust the fuel pump:

• When operating at altitudes from 1500 to 2000 m above sea level, the pump performance is reduced by 10%.
• At 2000 -2500 m - reduced by 15%.
• At 2500 - 3000 m - reduce to 20%.

Operating the tractor above 3000 m is not recommended.

Activities when running in a tractor

An important aspect in the process of successful commissioning of new equipment, as well as tractors after repair or long-term storage, is compliance with special routine maintenance operations. Carrying out all measures ensures the safety and preservation of the working life of all units and components when the tractor is put into operation.

The engine is a four-cylinder, four-stroke in-line diesel engine with direct fuel injection. The unit produces a maximum torque of 290 Nm at a set crankshaft speed of 1400 rpm. The engine displacement is 4.75 liters. The TO-49 backhoe loader provides fuel consumption within 220 g/kW*h. The motor design guarantees a minimum torque reserve of 15%. The fuel tank capacity is 130 liters.

Transmission

The TO_49 backhoe loader is equipped with a manual gearbox that doubles the number of gears. The machine uses a dry single-plate clutch. The number of forward gears is 18, reverse gears are four. The transport speed of the vehicle is 18 km/h. Maximum - 33.4 km/h.

To ensure uninterrupted operation, the equipment is equipped with a differential with a locking system in three positions:

• Automatic blocking;
• forced blocking;
• locking with hydromechanical booster.

Hydraulic system

The TO-49 Amkodor backhoe loader has a load capacity of 3200 kg. The maximum pressure created by the hydraulic system pump is 200 kgf/cm. The pump capacity is 45 l/min. The hydraulic system is filled with 21 liters of lubricants.
