Engine assembly should pay attention

1. Pay attention to the technical parameters such as the model number on the engine's brand name. Due to the different models and manufacturers of the engine, there may be many variations. The power, speed, and the size and structure of the corresponding parts may also be different. If you do not pay attention to these details in the process of assembly or assembly, it is very likely that you will create some problems that you find hard to judge after assembly. For example: 135 series diesel engines, because this series of diesel engines are more variants, there are many types of construction machinery, generator sets, ships, locomotives and other forms. Certain parts of each type of diesel engine cannot be replaced or mixed. For example, there are more than a dozen pistons. The combustion chamber is not the same as some sizes. The replacement may cause mechanical failure.
2. Must carefully clean the internal and external surfaces of the engine and the lubricating oil channel cleaning link is a key link in the Engine Assembly process. It directly affects the initial running-in and service life of the engine. The disassembled engine parts and the body must use gasoline and diesel. Or other cleaners clean, and then use the compressed air carefully blow the net inside and outside the surface of the foreign particles, especially the cylinder head inlet pipe and the body inside the corner, but also should be carefully cleaned.
3. It should be assembled according to the instruction manual or other relevant technical data. Some models that haven't been touched by themselves. When the first repair, the internal structure and principle is not yet clear, you should first find relevant manuals or documents to understand the relevant The technical data and structure are well understood, not blindly dismantled, and necessary records are made; when assembling, measurements and assembly should be made according to relevant data to ensure that each assembly size is within the allowable range. For example, the clearance between the Piston and the cylinder liner, the bearing bush, and the piston ring must meet the requirements, otherwise failures are not easy to judge.
