To convert a vane type hydraulic pump to a hydraulic motor, which of the following would have to be done?

Correct Answer: Option B — Provide small springs between the vanes and the base of the vane slots.

Vane pumps rely on centrifugal force to extend vanes. To function as a motor, the vanes must be mechanically forced outward against the cam ring before rotation begins. Installing springs behind the vanes ensures they maintain contact with the ring, allowing the fluid pressure to initiate rotation.
