1. When assembling parts, pay attention to chamfering, removing burrs and flash. When installing locating pins, they cannot be driven in with iron tools. Under their completely proper fit, they should be pushed in by hand for about three-quarters of the length and then tapped in gently.
2. To ensure the assembly quality, requirements such as assembly clearance, interference amount, flexibility, and meshing mark should be adjusted, proofread and technically inspected while assembling.
3. Assembly personnel must understand the purpose, structure and working principle of the assembled machinery. Study and be familiar with the functions of components and the connection methods among them, and be familiar with the assembly process and technical requirements.
4. The friction surfaces of moving parts should be smeared with appropriate lubricating oil. The tools for oil filling must be clean and dust-proof with a cover.
5. Count and collect all the required components, and prepare construction materials, tools and equipment, including lifting facilities.
6. For all parts, further cleaning and technical inspection are required to avoid rework after assembling unqualified parts. Especially the channels for hydraulic, pneumatic and lubrication should be cleaned more cleanly.
7. For all mating parts and non-interchangeable parts, they should be assembled in pairs or sets according to the marks made during disassembly, repair or manufacture, and chaotic assembly is not allowed. For important rotating parts, tests should be carried out as required, and only after passing can they be allowed to be assembled.
8. Seals cannot be installed backwards. In order to ensure sealing, when installing various gaskets, it is allowed to smear engine oil, sealant, etc.
