How many situations will occur during the use of the tractor, among which oil leakage is the most common one. There are various forms of oil leakage. How should we deal with it?

Switches include water valve, fuel tank switch, gasoline switch, etc. If the ball valve is worn or rusted, remove the rust between the ball valve and the seat hole, and select a suitable steel ball instead. If the sealing packing and fastening thread are damaged, repair or replace the fasteners and sealing packing. If the cone joint surface is not tight, it can be ground with fine valve sand and engine oil. Head oil leakage

Pipe joints include conical joints and hollow bolt pipe joints. The conical joint pipe joint includes two ends of the pressure gauge, one end of the gasoline pipe, two ends of the high-pressure oil pipe and the pipe joint from the crude fuel filter to one end of the oil transfer pump. If the high-pressure oil pipe joint is worn, deformed or cracked, it can be sawn off, replaced and welded. If the low-pressure oil pipe joint is damaged, the bell mouth can be sawed off and the bell mouth can be made again. If the thread is damaged, repair or replace it with a new one. Hollow bolt pipe joints include fuel coarse and fine filters and low-pressure oil delivery pipe joints of fuel injection pump. If the gasket is damaged or assembled unevenly, it can be replaced with plastic gasket, or flattened with assorted file, or polished with sandpaper, and milled with milling machine if it is serious. If there are pull marks on the pipe joint assembly plane, the joint assembly plane and gasket can be smoothed with fine sandpaper or oilstone; If there are impurities on the mating surface, pay attention to the cleanliness of the machine body during assembly, and the joint fixing bolts shall be tightened evenly. Joint oil leakage

Plane joints include two planes sealed with paper pad, asbestos pad and cork. If the contact surface is uneven or there are groove marks or burrs on the contact surface, it shall be polished with assorted file, fine sandpaper or oilstone according to the unevenness of the contact surface, and the large parts can be milled with machine tool. In addition, the assembled gasket shall be qualified and clean at the same time. If the bolts are loose, tighten each fixing bolt. Shaft oil leakage

The rotary shaft includes the shift lever shaft of the starter, the clutch handle shaft and the pressure reducing shaft of the engine. If the shaft and hole wear each other, the shift lever shaft and clutch handle shaft of the starter can be cut out of the sealing ring groove on the lathe. At this time, only install the sealing snap ring of corresponding size. If the rubber ring of pressure reducing shaft fails due to aging, replace it with a new one
