Question 1 of 27070

In a diesel engine starting motor equipped with a Bendix drive, the pinion moves and meshes with the flywheel ring gear due to __________.

🔍 Key Concepts

• Bendix drive operation in diesel engine starting motors • How a spiral helix / screw-type engagement can move a pinion gear along a shaft • The role of relative rotation versus centrifugal force or linkage in engaging the flywheel ring gear

💭 Think About

• Ask yourself: In a Bendix drive, what actually causes the small pinion gear to slide along the shaft into the flywheel—does something PUSH it, or does it THREAD itself along a spiral? • Consider whether the Bendix relies on electrical force at the flywheel, centrifugal fling-out, or a mechanical screw/helix between the pinion and shaft. • Think about which option best describes motion caused by the starter shaft beginning to turn while the pinion is still momentarily at rest.

✅ Before You Answer

• Verify which choice mentions a spiral or helical sleeve that the pinion can travel on. • Eliminate any options that rely on external levers or forces acting at the flywheel itself rather than along the starter shaft. • Confirm that the correct mechanism depends on relative rotation between the pinion and starter shaft, not on the flywheel generating a force.
