Question 360General Subjects - QMED

The correct answer is D) "D" is not kept clean. The hydraulic pump can begin to cavitate if the filter or strainer ("D" in the illustration) is not kept clean. Cavitation occurs when the pump is not able to draw in enough fluid, often due to a clogged or dirty filter, which can cause the pump to lose efficiency and potentially become damaged. Keeping the filter or strainer clean is crucial to maintain proper hydraulic system operation and prevent cavitation. The other answer options are incorrect because they do not directly relate to the causes of cavitation in the hydraulic pump. "A" being open or "B" being over-tightened would not necessarily lead to cavitation, and "C" removing "H" would not directly impact the pump's ability to draw in fluid.
