🔍 Key Concepts

• Hydraulic starting systems: how mechanical motion is transmitted from the starter to the engine flywheel • Overrunning clutch (sprag or Bendix type): its role between the starter and the engine • Difference between problems that stop the motor from turning vs. problems that stop power from reaching the engine

💭 Think About

• Ask yourself: in this question, is the hydraulic motor itself rotating normally, or is the problem between the motor and the engine? • Which option would allow the starter motor to spin freely but prevent the engine flywheel from being driven? • Which choices would more likely cause slow or no motor rotation at all, rather than a free-spinning motor with no engine movement?

✅ Before You Answer

• Confirm that the question states the hydraulic starting motor turns, so the hydraulic power supply and fluid condition are at least sufficient for rotation • Identify which component directly couples the starter’s rotation to the engine flywheel • Eliminate any answers that would primarily cause no or sluggish motor rotation, not a disconnect between motor and engine
