    Why is there insufficient air pressure in the bottle of my Belarus BELARUS-1523 Tractor?
    • M
      mcmahonandrewAug 19, 2025
      If you have insufficient air pressure in the air bottle of your Belarus tractor, it could be due to several reasons. There might be air leakage, which you should eliminate. The pressure regulator operation could be disturbed, requiring you to remove the pressure regulator and send it to the workshop for repair. Alternatively, the suction or pressure valve of the compressor might be faulty, needing cleaning from coke deposits or replacement if excessively worn. Finally, there could be excessive wear or jamming of the compressor piston rings, which would require cleaning from coke deposits or replacement.

    What to do if the air pressure in the bottle of my Belarus BELARUS-1523 Tractor drops quickly when I brake?
    • A
      Andrea CruzAug 21, 2025
      If the air pressure in the bottle of your Belarus tractor drops quickly when you step on the brake pedals, it could be due to a warped, clogged, or damaged inlet valve. In this case, eliminate the warpage, clean or replace the valve. Alternatively, the brake valve diaphragm may be damaged, requiring a replacement.

    Why is no warm air being fed to the cab of my Belarus Tractor?
    • J
      Jason ScottAug 26, 2025
      If no warm air is fed to the cab of your Belarus tractor, it could be due to several reasons. First, there might be no water circulation through the heating unit, so open the tap. Second, ice plugs may have formed in the heater hoses, so break the ice and pass hot water through the hoses. Third, the heater fan may not be operating, so remove the fan fault and check the electric circuit for switching on the fan.

    Why does the pressure in the air bottle of my Belarus Tractor drop quickly when the engine is stopped?
    • M
      Michael BriggsAug 28, 2025
      If the pressure in the air bottle of your Belarus tractor drops quickly when the engine is stopped, it is likely due to air leakage through coupling elements of the pneumatic system. Eliminate the leakage to resolve this issue.

    How to fix alternator noise in my Belarus BELARUS-1523 Tractor?
    • S
      Sandra McdonaldAug 30, 2025
      If you are experiencing alternator noise in your Belarus tractor, it may be due to slipping or excessive tension of the alternator drive belt. Remove the alternator and send it to the workshop for repair. Adjust the tension of the alternator drive belt.

    Why is the air passed to the cab of my Belarus BELARUS-1523 so humid?
    • N
      nmooreSep 1, 2025
      If the air passed to the cab of your Belarus tractor has high humidity, it could be due to water leakage in the heater radiator. In this case, eliminate the leakage or replace the radiator. It could also be due to water leakage in the connections of the heater system, so tighten the buckles.

    What to do if the electromagnetic clutch of the compressor fails to operate in my Belarus BELARUS-1523?
    • M
      Maria BrandtSep 3, 2025
      If the electromagnetic clutch of the compressor in your Belarus tractor fails to operate, and you don't hear a metallic click when turning the temperature regulator, it could be due to electric equipment failure. Check the operability of the block of pressure sensors by means of a tester or multimeter; the leads of the block of sensors (red and pink wires) shall be rung out between one another. Also, check the intactness of the connections of the electric circuits from the compressor coupling to the air conditioner control panel.

    Why does the air conditioner fan motor in my Belarus BELARUS-1523 Tractor fail to operate?
    • F
      Francisco LevineSep 5, 2025
      If the air conditioner fan motor fails to operate in your Belarus tractor, it is likely due to an electric equipment fault. Check the intactness of the respective fuse (25 ?, see electric diagram) on the fuse block located in the dashboard. Replace the blown out fuses by new ones. Check the presence of supply voltage at the air conditioner motor M7 by means of a test lamp when the switch is set to the ON position and the battery is connected. If the electric circuits are intact, but no supply voltage is present at the motor ?7, replace the switch.

    Why are the trailer’s brakes ineffective when using my Belarus Tractor?
    • J
      Jared StephensSep 7, 2025
      If the trailer’s brakes are ineffective when using your Belarus tractor, it could be because the brake valve fails to maintain the pressure in the control mainline at the level of 0.77...0.80 MPa (7.7...8.0 kgf/cm2). You can adjust the brake valve and its actuator. Alternatively, the brake valve might fail to drop the pressure in the coupling mainline to zero, so adjust the brake valve and its actuator.
