Question 56Motor Plants - QMED

The correct answer is D) Bendix drive or similar mechanism. The pinion of an auxiliary diesel-electric starting motor normally engages the flywheel ring gear by means of a Bendix drive or similar mechanism. This is a common method used to connect the starting motor to the engine's flywheel, allowing the starting motor to crank the engine and start it. The other options are incorrect because: A) a magnetic type coupling is not typically used for this purpose, B) an automatic follow-up mechanism is not involved in the starting motor's engagement, and C) a muff coupling and release mechanism is not the standard way the starting motor connects to the flywheel.
