Which of the following statements will be true if the position of the manual control lever, shown in the illustration, remains unchanged after the pump is placed on stroke? Illustration GS-0039
AI Explanation
The correct answer is A) Although oil will leak past part 'B', the amount of pump stroke will be maintained until the control handle position is changed.
This is correct because, in a hydraulic system, if the manual control lever position remains unchanged, the pump stroke will be maintained even if there is some internal leakage (oil leaking past part 'B'). The pump displacement will not fluctuate (as stated in option B) or gradually move to full or neutral stroke (as stated in options C and D) unless the control handle position is changed.
The other options are incorrect because they do not accurately describe the behavior of the hydraulic system when the manual control lever position remains unchanged.
