When an engine fitted with a hydraulic starting system starts up, the starter is protected from the higher speed of the engine by ________.

🔍 Key Concepts

• hydraulic starting systems and how they transmit torque to the engine during cranking • purpose and operation of an overrunning clutch in any starter system (electric, air, or hydraulic) • what happens to the starter drive when the engine speed becomes higher than starter speed

💭 Think About

• Think about which part of a starting system is specifically designed to disconnect or freewheel once the engine fires and runs on its own. • Ask yourself: if the engine suddenly accelerates above starter speed, which option would actually prevent damage to the starter’s gears or drive mechanism? • Compare how a starter in a car or small diesel disengages once the engine starts—what component does that job, and which option here matches that function in a hydraulic system?

✅ Before You Answer

• Verify which option describes a device that allows the starter shaft to turn the engine, but not be driven by the engine once it starts. • Eliminate any choices that only change pressure or valve positions but do not clearly provide a mechanical ‘one‑way drive’ or freewheeling action. • Confirm that the correct choice is a mechanical protection that works automatically when engine speed exceeds starter speed.
