Technician A says one of the common pump tests is
called the zero swashplate calibration. Technician B says
as a pump's internal leakage increases, its efficiency
increases. Who is correct?
Select one:
a. Technician A
b. Technician B
c. Both A and B
d. Neither Anor B

Solution

Answer

a. Technician A Explanation 1. Evaluate Technician A's statement Zero swashplate calibration is indeed a recognized pump test in hydraulic systems, so Technician A is correct. 2. Evaluate Technician B's statement Increased internal leakage reduces volumetric efficiency of a pump, not increases it. Technician B is incorrect. 3. Determine correct choice Only Technician A is correct.
