What should be checked on hydraulic pumps?

The hydraulic pump system is critical for the operation of the MH-60S, and ensuring that the fluid level is appropriate is vital for its proper functioning. Checking the fluid level is crucial because it directly impacts the ability of the hydraulic system to generate the necessary pressure for operation. If the fluid level is too low, it can lead to cavitation, reduced performance, and potential damage to the pump and system components.

While the fluid type and fluid color can provide information about the system's health and integrity, they do not immediately impact the operational capability of the hydraulic pumps in the way that fluid level does. Fluid temperature is also a significant factor, but it pertains primarily to the operating conditions and efficiency rather than the basic operational readiness of the hydraulic system. Therefore, verifying the fluid level is an essential maintenance task that ensures hydraulic systems are adequately supplied to perform optimally.
