When performing a lubrication interval check, what is the purpose of following the lubrication chart in the maintenance manual?

• A. Ensures components are properly lubricated to minimize wear and prevent seizure; prevents over/under-lubrication; ensures lubricant type and interval.
• B. To determine color coding of lubricants.
• C. To schedule inspections only and not actual lubrication.
• D. To identify which components do not require lubrication.

Answer: (A)

Using the lubrication chart ensures you apply the right lubricant on the right components, at the right intervals. This keeps moving parts properly lubricated, reduces friction and wear, and helps prevent seizure of bearings and gears. The chart specifies the exact lubricant type and grade, the correct amount to apply, and how often to re-lubricate, taking into account operating conditions. Following it also helps prevent over-lubrication, which can squeeze seals, attract dirt, and cause heat buildup, as well as under-lubrication, which accelerates wear. In short, the chart provides a standardized, evidence-based procedure so lubrication is accurate and effective across components and conditions. The other options don’t fit this purpose: color coding isn’t the focus, lubrication charts aren’t only about scheduling inspections without actual lubrication, and they don’t define which components don’t require lubrication.
