1. The friction surface of sliding bearings, axle necks and relative motion should be coated with engine oil during assembly. 07 During the assembly process, check whether there is any movement incoordination between the moving parts at any time. 08 It is necessary to clarify the nature and requirements of the fittings, and master the technical standards of over-over-over matching and gap matching.
2. Take the overhead camshaft engine as an example, the assembly order is as follows: Installation of the crankshaft flywheel group: install the flywheel on the flange at the rear end of the crankshaft. When installing, first position it with two positioning bolts, and then tighten the nut. When tightening the nut, the angle should be crossed, and the tightening moment should be 137~147Nm.
3. The assembly precautions of the main parts of the engine are as follows: the installation of the cylinder liner is a consumable part of a diesel engine, and its installation points include: (1) Put the cylinder liner without a water stop ring into the cylinder block to make it rotate flexibly without obvious shaking. At the same time, check whether the step size of the cylinder liner meets the specified range.
4. Install the bearing cover in order, first tighten it alternately in the diagonal direction; the fifth bearing cover, and then cross the diagonally tighten the third bearing cover, and tighten the torque of 20Nm.(5) Install the camshaft oil seal, but don't press it to the end, so as not to block the oil return hole. ( 6) Install camshaft timing gear.
5. Step 1 The whole process of automobile engine assembly line is as follows: the bottom of the cylinder block is facing down, the cylinder block, crankshaft, camshaft feeding, cleaning, blowing, diesel engine model, marking printing. After the cylinder block is flipped 180°, type the number to confirm. After the cylinder is turned over, the bottom of the cylinder is facing up.
1. Engine Assembly Safety Operating Procedures 01 Before assembly, parts must be carefully cleaned to keep the equipment, tools and workplace clean. Pay attention to carefully check and thoroughly clean all the lubrication channels on the cylinder block and crankshaft, and useCompressed gas/02 non-interchangeable parts, such as cylinder blocks and flywheel shells, piston connecting rod groups and their corresponding cylinders, etc.
2. Pay attention to the upper edge groove of the piston and the convex point of the connecting rod body and the connecting rod cover facing the same side, that is, the front of the engine).
3. Before assembly, all parts, components, lubricating oil, tools, workbench, etc. It should be thoroughly cleaned and dried with compressed air. Before assembly, check all bolts and nuts and replace them if they do not meet the requirements; washers, gaskets, open pins, locks, lock wires, washers, etc. All should be replaced during the overhaul.
4. Installation steps of the piston ring 1) After cleaning the selected piston ring, classify it according to the gas ring and oil ring, and pay attention to the cross-sectional structure and installation order. The side with the "TOP" mark on the piston ring of the Santana car must be installed facing up.2) Install the oil ring first. For the combined oil ring, install the lining ring first, and then install the scraper.
5. The assembly precautions of the main parts of the engine are as follows: the installation of the cylinder liner is a consumable part of the diesel engine. Its installation points include: (1) Put the cylinder liner without a water stop ring into the cylinder block to make it rotate flexibly without obvious shaking. At the same time, check whether the step size of the cylinder liner meets the specified range.

Its installation points include: (1) Put the cylinder liner without a water stop ring into the cylinder block to make it rotate flexibly without obvious shaking. At the same time, check whether the step size of the cylinder liner meets the specified range.
After the cylinder is installed with a new rubber seal, install it in the cylinder block and press it with a special tool. Use a special measuring tool to measure the protrusion of the cylinder liner relative to the top of the cylinder block.
When installing the engine, all pipes and wires should be restored to their original position; there should be enough gap between all moving parts and heating parts. During the assembly process, special tools should be used as much as possible to prevent damage to parts. Pay attention to fire prevention and leakage prevention.
Parts preparation and accompanying process Parts, unpacking, cleaning, delivery assembly line Engine parts assembly process cylinder head: pressure valve oil seal → loading into the drain → installing valve lock clip → loading and shaking Arm assembly → loading the exhaust manifold → sending the assembly.

After the cylinder block is flipped 180°, type the number to confirm. After the cylinder is turned over, the bottom of the cylinder is facing up.
Install the bearing cover in order, and first tighten it alternately in the diagonal direction; the fifth bearing cover, and then cross the diagonally tighten the third bearing cover, and tighten the torque of 20Nm. ( 5) Install the camshaft oil seal, but don't press it to the end to avoid blocking the return oil hole. ( 6) Install camshaft timing gear.
Take the overhead camshaft engine as an example, its assembly order is as follows: Installation of crankshaft flywheel group: install the flywheel on the flange at the rear end of the crankshaft. When installing, first position it with two positioning bolts, and then tighten the nut.When tightening the nut, the angle should be crossed, and the tightening moment should be 137~147Nm.
The general order of engine assembly is as follows: (Take the overhead valve gasoline engine as an example) 1. Install the crankshaft If the thrust gasket is on the first spindle neck, first install the timing gear and thrust gasket on the crankshaft neck.
After installing the cylinder head, start the engine. After the temperature is normal, check it again in the prescribed order and torque. Installation steps: Install the cylinder pad on the upper plane of the cylinder block, and align the mark and position as needed. Place the assembled cylinder head assembly steadily and gently in this position to avoid moving the cylinder cushion.
Step one car engineThe whole process of the assembly line is as follows: the bottom of the cylinder is facing down, the cylinder block, crankshaft, camshaft feeding, cleaning, blowing, diesel engine model, label printing. After the cylinder block is flipped 180°, type the number to confirm. After the cylinder is turned over, the bottom of the cylinder is facing up.
When installing the engine, all pipes and wires should be restored to their original position; there should be enough gap between all moving parts and heating parts. During the assembly process, special tools should be used as much as possible to prevent damage to parts. Pay attention to fire prevention and leakage prevention.
The assembly process of the engine is generally based on the cylinder block, assembled from the inside to the outside. During the assembly process, it should be installed, checked and adjusted to ensure the assembly quality.
Parts preparation and accompanying process parts, unpacking, cleaning, delivery assembly lineEngine parts assembly process cylinder head: press-loading valve oil seal → loading the gate → installing the valve lock clip → installing the rocker arm assembly → loading the row manifold → sending the general assembly.
Assembled in segments from the inside to the outside. Engine preparation before assembly: Before assembling the engine, all parts should be carefully cleaned. Blow dry and wipe clean. Make sure it is clean. The parts should be free of burrs, scratches, carbon and dirt. The cylinder block should be specially inspected and cleaned.
