Why my MTZ 920 engine fails to start?
Your MTZ Tractor engine might fail to start due to air in the fuel system or a faulty fuel pump. Try pumping the system with the manual priming pump, and eliminate air inflow if necessary. If the problem persists, the fuel pump may need repair by a qualified shop.
How to restore full power to my MTZ 920 engine?
If your MTZ Tractor engine isn't developing full power, several factors could be responsible. First, check the fuel feed, as misalignment of the fuel pump control rods can cause this issue; if misaligned, adjust the control rods. A clogged fuel fine filter can also restrict fuel flow, so replace the filtering element. Faulty injectors can hinder performance; locate, wash, and adjust them as needed. Ensure the fuel injection advance angle is correctly set. Lastly, a clogged engine air cleaner can limit power, so service the air cleaner.
Why is the oil pressure low in my MTZ Tractor's heated engine?
Low oil pressure in a heated MTZ Tractor engine can stem from several causes: a faulty pressure sensor or indicator (replace with new ones), a faulty engine lubrication system pump (eliminate the failure or replace the pump), or low oil level in the crankcase (add oil to the upper mark). Other potential issues include a sticking drain valve of the centrifugal oil filter (wash the valve and adjust the pressure) or maximum wear of coupling “crankshaft journal – bearings” (send the engine for repair).
What causes unstable idling in my MTZ 920 Tractor engine?
Unstable idling in your MTZ Tractor engine can be due to a few reasons: air in the fuel system (remove the air), an improperly adjusted idling spring in the fuel pump (adjust the idling spring for engines with fuel pump 4???? or 4????), or a faulty fuel pump (remove the fuel pump and send it for repair).
What to do if my MTZ 920 engine overheats?
If your MTZ Tractor engine overheats, it could be due to cooling fluid boiling in the radiator or poor fuel atomization by the injectors. Clean the radiator from dirt and dust, and if necessary, clean the cooling system from scale. Also, adjust the fan belt tension. For poor fuel atomization, detect the faulty injectors, wash, clean, and adjust them.
Why MTZ 920 clutch does not transfer the full torque?
If the clutch on your MTZ Tractor isn't transferring full torque, it could be due to no free travel of the pedal (adjust the free pedal travel) or worn-out driven plate linings (replace the linings of the driven plate as an assembly).
What causes MTZ Tractor clutch to not disengage fully?
If the clutch on your MTZ Tractor isn't disengaging fully, it could be because the free pedal travel is increased (adjust the free pedal travel) or oil has entered the dry section of the clutch housing (replace the cup).
What to do if turbocharger rotor of MTZ 920 does not rotate?
If the turbocharger rotor on your MTZ Tractor isn't rotating (indicated by the absence of a typical high-tone sound), it could be due to foreign objects obstructing the rotor's movement (remove the inlet and exhaust branch pipes to remove the objects), jamming of the rotor in the bearing (replace the turbocharger), or higher oil emission from the compressor or turbine side, indicating a loss of air-tightness of turbocharger seals (remove the turbocharger and send it for repair).
