1、正確使用汽修工具，避免損傷機件工作表面。若必須用錘子擊打時，應墊以軟金屬沖棒或襯板，以防損傷零件或機體。
1. Use automotive repair tools correctly to avoid damaging the working surface of the components. If it is necessary to strike with a hammer, a soft metal punch or liner should be placed to prevent damage to the parts or body.
2、總成或零件分解時，應做標記。汽車里面的零件非常的多，缺件時間長了很容易忘記怎么再安裝，還有的零件有安裝方向要求的，應記住原來的方向或坐上標記，以防裝反。
2. When disassembling an assembly or component, markings should be made. There are a lot of parts in the car, and it is easy to forget how to install them if they are missing for a long time. For other parts that require installation direction, remember the original direction or mark them on the seat to prevent reverse installation.
3、零件清洗。清洗滾動軸承時，清洗液的溫度不宜過高。像橡膠件、非金屬摩擦片、鋁合金和鋅合金等類不能用堿性溶液清洗，以防銹蝕。
3. Part cleaning. When cleaning rolling bearings, the temperature of the cleaning fluid should not be too high. Items such as rubber parts, non-metallic friction discs, aluminum alloys, and zinc alloys cannot be cleaned with alkaline solutions to prevent rust and corrosion.
4、螺栓螺母的緊固。安裝螺栓的長度應適當，按照正確的操作要求擰緊，以防松動或零件變形。
4. Tightening of bolts and nuts. The length of the installation bolts should be appropriate and tightened according to the correct operating requirements to prevent loosening or deformation of the parts.
5、連接件的拆卸。拆卸螺紋連接件時，應注意螺紋旋轉的方向；對于多螺栓連接件，還應注意其拆卸順序，以防螺栓被擰斷。
5. Dismantling of connectors. When disassembling threaded connections, attention should be paid to the direction of thread rotation; For multi bolt connections, attention should also be paid to their disassembly sequence to prevent bolts from being twisted off.
6、油封、襯墊的安裝。需要注意襯墊的材料和厚度符合要求，以防松曠或密封不良。
6. Installation of oil seals and gaskets. It is necessary to note that the material and thickness of the gasket meet the requirements to prevent looseness or poor sealing.
