How much fluid does the hydraulic refill hand pump hold?

The hydraulic refill hand pump used in the MH-60S has a capacity of 1.3 quarts of fluid. This measurement is significant as it reflects the amount of hydraulic fluid that can be added to the system to ensure proper operation and functionality of the hydraulic components in the aircraft. Maintaining the correct fluid level is crucial for the hydraulic system to function effectively, as hydraulic systems rely on the incompressibility of the fluid to transmit force and operate various systems such as control surfaces, landing gear, and cargo handling equipment. Understanding the capacity of the pump helps personnel ensure that hydraulic levels are maintained within proper limits, preventing potential system failures or operational issues.
