Why is it difficult to start the tractor?
The agricultural production of Sanqiu is about to begin. The author interviewed relevant experts of the agricultural machinery department of Zhucheng City on the topic of difficult tractor start-up. The answer given by the experts of agricultural machinery is that there are many reasons that make it difficult for the tractor to start. When the tractor is difficult to start, it is necessary to find out the reasons in time and take different solutions. The common tractor startup difficulties are as follows: If the cylinder head nut is not tightened or if the cylinder head is damaged and the crankshaft is damaged, if there is a leakage sound at the joint surface of the cylinder head and the body, the cylinder head nut may not be tightened, or the cylinder head gasket may be damaged. If it is the former, it should be tightened as required. If the latter is the case, when the cylinder pad is not badly damaged, the asbestos thread can be used to make up for the damage, and in case of serious damage, replace the new pad. There are two reasons for the leakage of the intake and exhaust valves: First, the valve clearance is too small to close the valve and the valve clearance needs to be adjusted. The other is that there may be spots on the valve sealing cone surface, such as rust, carbon deposits and other debris, but also make the valve closed lax. The crankshaft can be cranked during the inspection. If there is a “buzzing, squeaking†sound in the air cleaner and the exhaust pipe, the inlet and exhaust valves will leak. The valve needs to be ground. When the piston ring wears excessively and rotates the crankshaft, the inside of the body (for example, the low oil shell) leaks sound, and the reason is mostly on the piston ring. Some clean oil can be added into the cylinder. If the compression force is increased after the addition, the piston ring should be replaced. The opening of the piston ring's counterpart piston ring moves to a straight line (commonly known as the counterpart), or the piston ring is stuck in the ring groove due to coke, and the cylinder cannot be popped out. The phenomenon is that when the crankshaft is turned, there is a sound of air leakage in the crankcase. The piston ring should be removed to remove coke. If the ring moves to a straight line, the positions of the openings should be evenly distributed, but the direction of the piston pin must be avoided. The loosening of the injector fixing bolt leaks at the injector on the cylinder head and it should be tightened. Other reasons, such as bearing bushes or copper sleeves, can make the crankshaft unable to turn; piston installation or air filter plugging also make the diesel engine unable to start. Although this type of situation is relatively rare, it is also worthy of attention.
