🔍 Key Concepts

• Common mechanical vs. electrical causes of vibration in rotating machinery • How mounting and alignment affect vibration in diesel generators • Typical symptoms of coolant leaks and governing/surging problems

💭 Think About

• Which of these choices would directly affect the balance or physical stability of the rotating assembly? • Which options would more likely show up first as changes in temperature, load, or exhaust condition rather than vibration? • If the generator is securely mounted and properly aligned, what types of problems would you expect to notice before vibration becomes severe?

✅ Before You Answer

• Identify which options are primarily mechanical issues versus electrical or combustion issues • Consider which condition would most immediately cause noticeable shaking of the unit or skid • Ask yourself which problem is commonly found and corrected during routine inspection of the foundation and fastenings
