Question 141Motor Plants - Assistant Engineer

The correct answer is A) '7'. The wrist pin, also known as the gudgeon pin, is the component that connects the connecting rod to the piston in a diesel engine. In the illustration MO-0122, the wrist pin is clearly labeled with the number '7', confirming that A) '7' is the correct answer. The other answer choices are incorrect because they do not correspond to the component labeled as the wrist pin in the illustration. B) '17' refers to a different engine component, C) 'G' is not a label used in the illustration, and D) 'S' is also not the label for the wrist pin.
