Small Four-Wheeled Tractor Common Faults and Solutions
Small four-wheeled tractors are widely used in agricultural production due to their convenience and mobility. During the use of small four-wheeled tractors, various faults may occur. What are the common faults and solutions of small four-wheeled tractors? Let us have a look.
First, the fault reason and solution of the detaching of the clutch: the most common cause of this problem is that the lining is worn or that the gap between the friction plate and the pressure plate is not suitable, so that no contact can be made during the start-up process. At this time, the owner should replace the old friction plate and pressure plate with a new one, and the gap should be adjusted appropriately.
Second, when the two gears are engaged, the speed is slow and the acceleration is weak. This problem is generally caused by too small clearance between the gear shaft and the gear sleeve, so that too much friction is caused during the gear shifting process, resulting in slow speed. When this problem occurs, the owner should adjust the clearance between the gear shaft and the gear sleeve in time, so as to make the gear shift more smoothly.
Third, the engine vibration is too large: generally, the main axle of the four-wheeled tractor is bent, the crankshaft is worn, the cylinder is not concentric with the crankshaft, the spark plug does not work well, or the air filter airway is blocked. When these problems occur, the owners can first use a straight ruler to check the frame, and then use a dial gauge to check the crankshaft and cylinder. Finally, either clean the spark plug and air filter or replace them with a new one.
Fourth, there is a knocking sound in the cylinder head: the most common cause of this problem is the overheating of the cylinder. If this is the case, the owner should turn off the engine in time, replace it with a new cylinder head gasket, and then observe whether the knocking sound is still there. In addition, when the owner adjust the valve timing, if he does not pay attention to the valve clearance, this problem may also occur.
Finally, the small four-wheeled tractors bearing is in bad condition: generally, the main reason for this is that the bearing is short of lubricating oil, so its life will be greatly shortened. Therefore, it is necessary to check the lubrication condition regularly during the use of the small four-wheeled tractor. If the oil is found to be insufficient or the bearing is found to be severely worn, it should be replaced in time.
In summary, these are some of the common faults and solutions of small four-wheeled tractors. Under normal circumstances, you can find the cause and solution of the fault through regular inspection and maintenance of the various components of the four-wheeled tractor, but if you still cannot find the cause of the fault, it is recommended that you find professional technicians to help you solve it.
