Before the tractor is put into use, it shall be operated for a period of time under the specified conditions of lubrication, rotation speed and load, and necessary inspections, adjustments and maintenance shall be carried out to normalize the technical status. This series of work is called running-in. Newly purchased or overhauled tractors must be worn in order to be put into use, otherwise the life of the tractor will be shortened.
First, the engine idle running in accordance with the instructions specified in the order to start the engine, the engine first by the low speed, medium speed, high speed, that is, by the small throttle, the throttle, the throttle in order, followed by running each 5 minutes.
During the idling of the engine, the working conditions of the engine, the air compressor, and the hydraulic oil pump should be carefully checked to observe whether there is any abnormality or sound and check whether there is any leakage, leakage, or leakage of gas and whether the instrument is working properly. When it is found that there is an abnormal phenomenon, it should immediately stop, rectify after troubleshooting.
Second, the power output shaft no-load running-in engine throttle control handle placed in the throttle position, the engine running at medium speed, respectively, so that the power output shaft at low speed, high speed, each running for 5 minutes, check for abnormal phenomena. After running-in, the power output shaft must be in the neutral position.
Third, the hydraulic system running start the engine will throttle on the throttle position to operate, manipulate the dispenser handle, lift the suspension mechanism several times, observe whether there is an abnormal phenomenon. Then hang a weight of about 500-800KG on the surface of the suspension and the mass of the farm implement is equivalent to make the engine run under the throttle position and manipulate the handle of the distributor so that the suspension mechanism can go up and down in full stroke, and the number of times is not less than 20 Times. Check whether the hydraulic suspension mechanism can be fixed in the highest position or required position, lifting time and whether there is leakage.
When the tractor is stationary, the engine runs at low, medium, and high speeds. Steering the steering wheel steadily to the left and right 10 times. Observe the follow-up situation of the tractor's front and rear steering. The sound is normal and the steering wheel is light and smooth. If a fault is found during the running-in process, the cause should be analyzed and eliminated.
Fourth, tractor empty driving and load running-in When the engine idling running, power output shaft and hydraulic system running, confirm that the technical state of the tractor is completely normal, before the whole running-in, the running order and time according to the instructions in the specification, total Run in 60 hours. When running at idle, turn at a low speed and properly use a single-sided brake, and test the emergency brake at high speed. After idling, when the tractor's technical state is completely normal, the load can be run in. When the load is running in, the load must be from small to large, and the gear from low to high.
