What happens if a lubrication system lacks a means to add lubricant?

1. The motor runs efficiently without lubrication

2. It requires frequent replacement

3. Bearings must be disassembled for repacking

4. It causes rapid engine wear

The correct answer is: Bearings must be disassembled for repacking

A lubrication system that lacks a means to add lubricant leads to significant operational issues. The primary function of a lubrication system is to reduce friction between moving parts, such as bearings, and to dissipate heat generated during operation. If no lubricant can be added, the existing lubricant will eventually break down or get contaminated. In this scenario, without the ability to add new lubricant, components like bearings can wear down rapidly due to excessive friction and heat. This deterioration would necessitate disassembling components to repack them with fresh lubricant, which is more labor-intensive and time-consuming than simply adding lubricant to a functioning lubrication system. Regular maintenance, including adding lubricant, is critical to maintaining optimal operation and lifespan of machinery; failures to address this can lead to severe consequences for the equipment's functionality and reliability. Therefore, the need to disassemble bearings for repacking highlights the critical maintenance requirements that arise when a lubrication system is lacking the means to replenish its lubricant.
