Clever dismantling the cylinder head When repairing the agricultural vehicle engine, when it is difficult to remove the cylinder head, after loosening the cylinder head nut, use the hammer to knock lightly around the cylinder head, and then shake it with the screwdriver handle. Turning the crankshaft, the cylinder head can be easily removed by means of the piston compressed air. The oil leakage gasket of the oil pipe is a convex injector at both ends of the high pressure oil pipe. The concave surface on the tight seat of the oil valve is connected with no gasket in the middle and does not leak oil. However, if it is used for a long time, once the contact surface is worn, it will When the oil leaks, a round piece of copper can be cut from the waste cylinder pad, a small hole can be drilled in the middle, and the nut can be placed between the concave surface and the concave surface. Then the nut is tightened and the oil leakage problem is solved. The water-blocking ring is well-heated and installed in winter. Due to the cold weather, the water-blocking ring becomes brittle. When it is installed on the cylinder liner, it is easily broken. The hot water pre-heating method can be used to soak the water-blocking ring in warm water of about 60 degrees. Minutes, the installation is much easier after removal. The hot car lifts the residual engine oil for too long and needs to be replaced with a new one. The old oil may not be put on the net, resulting in residual oil residue in the oil pan. If the oil is lifted slightly before putting the oil, the hot car puts oil. The oil can be put clean. Cover gaskets are not broken. The valve cover gaskets of multi-cylinder diesel engines made of cork, although with good sealing performance, are easily broken. When installed, if they are coated with a layer of paint (only painted on them), they will cover the cover. When the cover is glued together, it is not easy to be broken when it is disassembled because it is integral with the cover.
