Repair the small doorway: In accordance with the "white smoke, water leakage; blue smoke, burning oil; black smoke, waste diesel" method to check what is wrong with the tractor. 1. If the tractor emits white smoke, it should stop to release the water in the oil. If the cylinder pad is damaged, the cylinder head and cylinder liner have cracks and the cooling water enters the cylinder, then the cylinder head gasket must be replaced and the cracks in the cylinder head and cylinder liner must be filled with adhesive. If the oil supply time is too late and the atomization is poor, the gasket between the high pressure oil pump and the gear chamber should be reduced. Second, the tractor was found to be emitting blue smoke, indicating that the engine oil had entered the combustion chamber. At this time, excess oil in the oil pan or air cleaner should be released. If the piston and cylinder liner, valve guide and valve stem are worn, the clearance is too large and should be replaced in time. It is also possible that the piston rings are worn, jammed, broken, mis-aligned or misaligned. Make the oil string and reinstall or replace it. Third, the emergence of regular black smoke, indicating poor fuel combustion, carbon particles in the exhaust, should clean the air filter or replace the lower viscosity diesel. If it is overloaded, the load should be reduced. If oil supply is too large or uneven, and the nozzle is not atomized, adjust the fuel injection pressure or replace the fuel injection head.
