Question: A field technician determines that a loader's hydraulic pump is cavitating. What corrective action involving the reservoir is most likely to reduce or eliminate the cavitation issue?
Answer options:
- Increasing the reservoir's capacity
- Lowering the oil level in the reservoir ✅ Ensuring the reservoir breather is clean and unrestricted
- Installing a smaller suction line filter
Correct answer: Ensuring the reservoir breather is clean and unrestricted
Explanation: A clean and unrestricted breather allows atmospheric pressure to properly act on the oil surface, ensuring adequate pressure at the pump inlet. A restricted breather can lead to a vacuum in the reservoir, exacerbating or causing cavitation by reducing the net positive suction head (NPSH) available to the pump.
