🔍 Key Concepts

• Effect of loose foundation bolts on rotating and reciprocating machinery • Typical symptoms of mechanical looseness and misalignment in compressors • What components (belts, unloaders, intercoolers) are directly affected vs. indirectly affected

💭 Think About

• Think about what happens physically to a heavy, fast-moving machine if it is not rigidly secured to its base. • Which of the listed symptoms is the most common direct result of that kind of movement? • Which options would require more specific internal failures, rather than just loose mounting?

✅ Before You Answer

• Identify which component is directly connected to the compressor frame and mounting. • Ask: which symptom would you expect to feel or see first when the unit is running with loose hold-down bolts? • Eliminate any options that describe failures inside subcomponents (like unloaders or intercoolers) that are not the most immediate effect of a loose base.
