The common sense of the deutz engine is as follows:
The valve spring of 1 F6L912 engine is variable pitch, and one end of the dense ring is placed in the lower part when installation. If it is installed, the trend of vibration increase will increase, and the wear of valve tube will be increased.
2 on the fuel injection pump gear, there are two marks "?" and ":" when the F6L912 engine is installed, the "mark" and "idler wheel" should be aligned.
3 the clearance between intake and exhaust gap is inconsistent with other 135 series engines, and the standard clearance is 0.15mm.
4 the rubber ring of round section is sealed in the upper and lower connecting part of the push rod pipe. The upper part is black or green fluorine rubber or chlororubber ring. The temperature resistance is -40 - 260 degrees Celsius, and the lower part uses the pink silicone rubber seal. Its temperature resistance is -20+150 perturbed, and a special installation is needed when the lower spring is installed. Tools, if there is no special tool, you can use the thin wire of 0.6-- [Phi] 0.8mm to wear the spring in advance and bind the compressed spring well. The pipe and oil seal are properly installed. After fastening the cylinder head, the wire is removed and the spring is automatically pressed. The practice has proved that this method has a good effect.
5 when the cylinder head bolts are dismantled, two bolts for each cylinder can not be disassembled with the ordinary 17mm sleeve, because the small hole sleeve is large, and the 17mm sleeve can be sold by the market, and the outer circle of the outer circle of the cylinder is about 1mm, and the cylinder head can be put into the cylinder head to disassemble the bolt.
6 the locking bolt of the front part of the crankshaft pulley is left (no note), and no locking piece is needed. When the disassembly is carried out, the rotation must be made clear so as not to "tighten the load more."
7 when introducing the camshaft, the camshaft failed to point out that the camshaft has only the first axle diameter (close to the end of the positive gear chamber), and the rest of the shaft diameter has no cam bearing because of the storage channel.
8 when replacing the shaft diameter, Dongfeng can be used to replace the bearing 360111, and the effect is good.
9 out of the fuel injector assembly, if there is no special tool to do the following tools, at one end of the tool, the internal thread of the vehicle is matched with the injector thread, and the 610mm * 400mm round steel is welded in the middle. The 610.5mm hole is drilled in the middle of the 650mm * 100mm round steel, then on the 610mm round steel, and at the other end of the 610mm round steel, the large flat mat of 50mm * 10mm is welded. Move the impact inertia through the 650mm round steel, that is, stay away from the injector.
10 the method of disassembly of the valve tube is not introduced. Because there is a ring on the outer circle of the valve tube, the valve tube can be removed from one direction, the cylinder head is turned over when dismantling, and the catheter can be pulled out with the suitable tool. If the direction is mistaken, it can not only make the catheter out, but also can damage the cylinder head.
