The five oil leakage problems and handling methods of the tractor are as follows: 1. The rotary shaft oil leakage rotary shaft includes the clutch handle shaft of the shifter shaft of the starter and the pressure relief shaft of the engine. In the event of oil leakage, the gearbox shaft and the clutch handle shaft of the starter can be cut out of the seal ring groove on the lathe, and the corresponding size of the seal ring can be installed. If the aging of the apron due to decompression shaft fails, replace the new apron. Second, the switch leak If the ball valve wear or corrosion, should remove the rust between the ball valve and the seat hole, and select the appropriate ball substitute. If the packing and fastening threads are damaged, the fasteners should be repaired or replaced and the packing replaced. If the conical joint surface is not tight, it can be ground with fine valve sand and oil. Third, if the pipe joint leaks oil due to deformation or cracking of the high pressure oil pipe joint, it can be sawn off and replaced with a good joint. If the connector of the low-pressure fuel pipe is damaged, the bell mouth can be sawed out and the bell mouth can be made again. If the thread is damaged, it should be repaired or replaced with a new one. Hollow bolt fittings include coarse fuel, fine filters, and low-pressure fuel injection fittings for injection pumps. If the gasket is damaged or the assembly is uneven, you can change the plastic gasket, or use it to repair flattening, or you can use sandpaper to grind flat, serious milling machine can be used for milling. If there is a pull mark on the assembly plane of the fitting, the fitting plane and the spacer can be smoothed with fine sandpaper or with a stone. If there are impurities on the mating surface, the body should be cleaned during assembly and the connector fixing bolts should be tightened evenly. Fourth, screw plug oil plugging oil plug plug plug oil plug section includes cone plugging, plugging and process plugging, if the plug screw is damaged or not qualified, should replace the new parts; if the screw screw is broken, can be added Large screw hole size, equipped with new oil plug. If it is worn due to taper, it can be changed to flat plug after tapping, and then it can be used again. V. Oil leakage from flat joints If the surface is uneven or there are grooves or burrs on the contact surface, according to the degree of unevenness of the contact surface, use assorted files, fine sandpaper or oil stone to flatten the surface. In addition, the assembly of the gasket to pass, while cleaning, put down. If the bolt is loose, tighten the fixing bolts.
