NEIEP Mechanics Practice Exam

Which of the following should not be disassembled in the field?

1. Oil buffers

2. Rope clamps

3. Slack adjusters

4. Brake assemblies

The correct answer is: Oil buffers

Oil buffers should not be disassembled in the field because they are precision components that require specific handling and calibration to ensure proper function. Disassembling them without the appropriate tools or environment can lead to contaminants entering the system, damage to the seals, and difficulty in reassembly to the manufacturer's specifications. This could compromise their ability to perform effectively, resulting in a potential safety hazard. Other components like rope clamps, slack adjusters, and brake assemblies might be designed for field maintenance and repairs with standard tools. These parts are typically more straightforward to maintain and can be reassembled adequately on-site without significant risk of malfunction, as they often involve simpler mechanical systems or are designed for easy adjustment. Thus, the complexity and precision involved with oil buffers make them unsuitable for field disassembly.
