AProvide small springs between the vanes and the base of the vane slots.
BProvide one additional slot and vane.
CDouble the casing thickness.
DInstall an enlarged control ring around the rotor.
AI Explanation
The correct answer is A) Provide small springs between the vanes and the base of the vane slots. To convert a vane-type hydraulic pump to a hydraulic motor, the key change is to provide small springs between the vanes and the base of the vane slots. This allows the vanes to be pushed outward by the springs, creating the necessary suction to draw in fluid and generate rotational motion, rather than just pumping fluid. The other options, such as adding an extra vane, increasing casing thickness, or installing an enlarged control ring, are not the primary modifications required to convert a pump to a motor.
