Before a new or repaired tractor is used for formal use, it must run at a specified speed, load, and time. Through the transition of the tractor from idle operation to a certain load, the working surface of each moving part is polished smooth and smooth, forming a working surface that can withstand heavy loads, so as to meet the requirements of normal operation under various load conditions.
There are certain skills in the running-in of the tractor. The main points are as follows: After the idling of the engine is started, the engine is started in the order specified in the instruction manual, and the engine is operated in the order of low speed, medium speed, and high speed for 5 minutes in sequence.
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.
Do a good job of the output shaft running at no load The engine throttle lever is placed in the throttle position. The engine is running at medium speed. The power output shaft is run at low speed and high speed for 5 minutes respectively to check for abnormal conditions. After running-in, the power output shaft must be in the neutral position.
Do a good job of starting the engine with the hydraulic system running in. Operate the throttle at the throttle position, operate the handle of the distributor, and lift the suspension mechanism several times to observe if there is any abnormality. Then hang a weight of about 500-800 kilograms or a farm implement of the same quality on the surface of the suspension so that the engine can be operated under a large accelerator position, and the handle of the distributor can be manipulated so that the suspension mechanism can be raised and lowered in full stroke, and the frequency 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 leakage phenomenon.
Do a good job of tractor empty driving and load running. When the engine idling, the power output shaft and the hydraulic system are running in, confirm that the technical state of the tractor is completely normal, then the whole machine can be run in. During coasting running, turn at a low speed and use a unilateral brake appropriately. At high speed, test the emergency brake. After coasting and running, when the technical state of the tractor 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 position should be from low to high.
