Question 1 of 27070

When a sudden increase in pressure occurs in a forced lubrication system, you should check for a __________.

🔍 Key Concepts

• Forced lubrication system behavior when flow is restricted or suddenly changes • Relationship between pressure, flow, and restrictions in piping systems • Typical symptoms of a cooler, bearing, or suction problem in a lube oil system

💭 Think About

• Ask yourself: if pressure suddenly goes UP, does that usually mean more flow, less flow, or a restriction somewhere? • Which choice would most likely cause oil to have a harder time moving through the system, forcing the pump to build more pressure? • Which options would more likely cause pressure to DROP instead of rise?

✅ Before You Answer

• Identify which options would normally cause low, not high, pressure and set those aside. • Think about where a partial blockage or restriction is most likely to occur among the listed components. • Consider whether a ruptured tube or high sump level would realistically create a sudden pressure spike in the discharge line.
