1. Impact on the precision of the motor assembly line: Parts should be replaced based on their required precision for operation. For example ； The basic components of machine tools, such as the bed guides, spindle, and bearings, are severely worn, which has a significant impact on working precision; they should be replaced ； If the wear is not severe and it is estimated to last until the next maintenance cycle, it may not need to be replaced. 2. Impact on fulfilling the intended functional requirements: When the components of the motor assembly line fail to fulfill their intended functional requirements, replacement should be considered. When the performance of the motor assembly line is reduced, replacement should be considered. 3. Impact on productivity: Although the components of the motor assembly line are still able to perform their intended functions, issues associated with the motor assembly line itself lead to increased working time and labor intensity, which cause malfunctions in the automated systems, an increase in defective products, and a significant drop in productivity; it is therefore necessary to consider replacing the relevant components. 4. Impact on the strength and stiffness of components in motor assembly lines: The strength and stiffness of some components in motor assembly lines have reached their minimum values; when wear is severe enough to risk damage, these components must be replaced. When reduced speed leads to a decrease in precision or disrupts normal operating conditions, replacement is necessary. For components where high safety standards are required, those that show signs of degradation or cracks must also be replaced. 5. Wear conditions: When the wear of components in the motor assembly line increases sharply, it disrupts proper fitting, meshing, and transmission, leading to reduced efficiency, increased heat generation, abnormal lubrication, reduced surface resistance to damage, as well as jamming or breaking – in such cases, the components need to be replaced ； If the surface hardening layer of a part is worn away or peeled off, if the fit clearance is too large, if the surface is damaged, or if there is fatigue corrosion, etc., the relevant parts should be replaced promptly to protect the more expensive matching components. 6. Economic analysis: When some components are approaching their failure limit but have not yet reached it, it is necessary to consider the impact of their remaining lifespan on future use and maintenance, and to analyze economically whether replacement is warranted and when it would be appropriate to carry out such replacement. Parts that allow for retrofit repairs can be used until their limit of lifespan ； When it is not possible to maintain a repair interval, and when replacement involves heavy labor, significant downtime losses, major impacts on production, and no alternative parts are available, then replacement is necessary ； Those with high safety requirements and no reliable monitoring methods should be replaced regularly, without giving too much consideration to their remaining lifespan.
