🔍 Key Concepts

• Effect of abrasive contaminants (dirt/metal particles) in lubricating oil systems • Typical failure modes of gear teeth under poor lubrication conditions • Relationship between oil condition and temperature/pressure in a lube system

💭 Think About

• Think about what happens when hard particles are carried between moving metal surfaces such as gears and bearings. • Which option describes a type of damage or failure, rather than an improvement, that would logically result from contaminated oil? • How would contamination affect the surface condition of gears and bearings over time: smooth and uniform, or pitted and broken?:

✅ Before You Answer

• Identify which choice describes damage to gear teeth rather than a system parameter change. • Ask whether dirt/metal particles are more likely to cause wear and surface breaking or a more uniform, smooth surface. • Consider if contaminated oil would realistically cause a drop in temperature or increase in discharge pressure, or if those are red herrings.
