Q

Which of the following conditions is most likely to occur if the electric starter motor pinion gear fails to disengage from the flywheel of a diesel engine after the engine has started?

🔍 Key Concepts

• How an electric starter motor engages and disengages from the flywheel ring gear • What happens to a small electric motor if it is forced to turn at very high speed for a long time • The difference between mechanical damage to gears and overspeed damage to the motor

💭 Think About

• Think about which part is designed to turn the other only briefly during starting, and what happens if they stay locked together once the large engine is running on its own • Compare the size and strength of the flywheel to the starter motor. If they stay engaged, which one is more likely to be damaged first, and how? • Consider which options involve air-start systems or combustion gases, and ask whether those are connected to an electric starting motor

✅ Before You Answer

• Verify that the question specifically mentions an electric starter motor pinion gear and a flywheel, not an air-start motor • Check which answer choices involve systems not used with an electric starter (such as an air-start manifold) • Consider which failure mode would most quickly lead to overheating, high RPM, or mechanical failure of the smaller component (the starter) rather than the heavy flywheel
