Question 55Motor Plants - 1st Asst/Chief

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 through a Bendix drive or a similar mechanism. The Bendix drive is a self-engaging mechanism that allows the starter motor to rapidly engage and disengage the flywheel, providing a smooth and efficient starting process for the diesel engine. 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 relevant to the starter motor engagement, and C) a muff coupling and release would not provide the necessary engagement and disengagement functionality required for the starting motor.
