How much fluid does the MGB hold?

The main gearbox (MGB) of the MH-60S is designed to hold 7.5 gallons of fluid. This amount is critical for optimal lubrication and cooling of the gearbox components during operation. Proper fluid levels in the MGB are essential for the efficient transfer of power from the engine to the rotor system, ensuring smooth operation and prolonging the lifespan of the gearbox.

Maintaining the correct fluid quantity helps prevent overheating and reduces wear on gears and bearings, which can lead to operational failure if not properly managed. Consequently, understanding the MGB fluid capacity is crucial for plane captains, as it directly relates to the maintenance checks and servicing procedures required to ensure the aircraft operates safely and effectively.
