1 Step 1 The whole process of automobile engine assembly line is as follows: the bottom of the cylinder is facing down, the cylinder, crankshaft and camshaft are fed, cleaned, blown and the diesel engine model and number are printed. . Once the cylinder is rotated 180°, place a number to confirm. Once the cylinder is turned over, the bottom of the cylinder faces up. Loosen the tile cover, remove the tile cover, install the upper and lower shaft tiles, install the piston cooling nozzle, insert the camshaft key, install the shaft thrust plate cams, hang the crankshaft and drive the key. Press the front pin into the rear pin, apply oil to the cylinder hole, install the piston, install the connecting rod cover, tighten the connecting rod bolts, and inspect the internal components. Install the end platefront of the diesel engine, install the engine filter assembly, apply glue to the oil pan, install the oil pan and tighten it. Confirmation of interior parts is recorded in the engine data sheet. After the connecting rod is numbered, disassembled and cleaned, the connecting rod is installed with the connecting rod shoe, piston weight group, piston heater, piston pin installation and piston ring installation. The cylinder body is rotated 180° with the top of the piston. cylinder upwards. 2 Step 2 Install the rear end plate, install the machine cooler, install the water pump assembly, install the vacuum pump assembly, install the vacuum pump lube oil pipe and install the fuel injection pump assembly. Install the fuel injection pump assembly, raise the cylinder head and tighten the cylinder head bolts. Install the rocker arm assembly, adjust the penny clearancepopes and fill the rocker arm shaft with oil. Check the valve clearances, install the breather, install the rocker cover assembly, install the fuel injector assembly, and install the small oil return hose assembly. Install the generator assembly, install the V-belt, install the exhaust pipe, install the exhaust pipe heat shield, and install the heater water pipe gasket. Install the high pressure oil pipe, tighten the thermostat bolts, apply glue to the front cover of the fuel injection pump, tighten it and install the intake pipe. Install the exhaust T/C wire to the EGR valve and inspect the appearance. Oil leak testing, oil filling, visual inspection Engine assembly line and online stand-alone special equipment: cleaning machine, bearing outer ring vibrating press, oil seal press, oil measuring machine'gap, guide clamping device
1) Remove the cylinder head mounting screws. Note that the screws should be loosened crosswise from both ends towards the middle. 2) Remove the cylinder seal and pay attention to the installation direction of the cylinder seal. 3) Turn the engine over and remove the oil pan retaining screws (note that the screws should also be loosened from both ends towards the middle). 4) Remove the oil pan and oil pan gasket. 5) Loosen the primary oil filter fixing screws and disassemble the oil filter, oil pump gear and oil pump. 6) Dismantle the engine piston connecting rod group and rotate the crankshaft so that the pistons of the 1st and 4th engine cylinders are at bottom dead center. 7) Remove the connecting rod fixing nuts of cylinders 1 and 4 respectively, remove the connecting rod bearing caps, pay attention to the connecting rod correspondence marks and replace thembe in order. 8) Use a rubber hammer or a hammer with a wooden handle to push out the piston rod from cylinders 1 and 4 respectively, catch it at the cylinder outlet with your hand and remove the piston rod. Pay attention to the. direction of piston installation. 9) Reinstall the connecting rod bearing cap, connecting rod bolts and nuts to their original positions. Connecting rods of different cylinders cannot be exchanged with each other. Use the same method to disassemble the piston and connecting rod groups of cylinders 2 and 3. 10) Remove the flywheel set from the engine crankshaft, loosen the flywheel fixing screws and remove the flywheel. The steering wheel is relatively heavy, so pay attention to safety when disassembling. Remove the front and rear crankshaft seal flanges and oil seals. 11) Loosen the crankshaft main bearing cap fixing screws from both ends to the middle, andPay attention to the assembly mark and orientation of the main bearing cap and the main bearing shells of different cylinders cannot be exchanged with each other. 12)Lift the crankshaft, return the main bearing cover and seal to the original position and lightly tighten the fixing screws. Pay attention to the positioning of the crankshaft stopper and the installation direction of the opening. General Engine Installation: 13) Install all parts in reverse order of engine disassembly.
