CEM Maintenance & Repair Strategies 2

Question 1

Which maintenance strategy uses real-time sensor data to predict when equipment failure is likely to occur?

Question 3

A fleet manager notices hydraulic fluid consumption has doubled over three months. What is the BEST first step?

Accepted Answer

Conduct a fluid leak audit and inspection of hydraulic lines and seals

Answer

A systematic leak audit identifies the source of abnormal consumption before committing to costly part replacements.

Question 4

In the context of repair decision-making, the 'repair vs. replace' analysis should consider:

Accepted Answer

Repair cost, remaining useful life, and replacement cost

Answer

A complete repair-vs-replace analysis weighs the cost of repair against remaining useful life, future reliability, and the cost of a replacement unit.

Question 5

Which lubrication practice is considered BEST for extending bearing life in heavy equipment?

Accepted Answer

Following the manufacturer's recommended lubrication intervals and grease type
