GSB1210005 - Tronair 06-5042-3600 – 8-Gallon Hydraulic Reservoir Service Cart – Skydrol/PE Fluids

The cart includes a 2-micron pressure filter that removes fine contaminants from Skydrol before it enters the aircraft system. This filtration prevents dirt or particulate matter from causing wear, blockages, or performance issues in sensitive hydraulic components. Regular filter maintenance is critical for ensuring ongoing protection and fluid cleanliness.

The service cart is equipped with a hand-operated pump specifically designed for phosphate ester compatibility. The pump delivers a displacement of 4.4 cubic inches (72.1 cc) per stroke, allowing efficient transfer of hydraulic fluid into the aircraft reservoir. Smooth, steady pumping ensures controlled delivery without introducing air into the system.

Operators should confirm that the reservoir contains the correct fluid type, check that the hose is securely attached, and ensure the protective cap is in place until ready for use. The cart should be positioned securely, and the pump should be tested for smooth operation. Performing these checks reduces contamination risks and ensures consistent performance.

The cart’s pneumatic tires should be maintained at 45 to 50 PSI (3.1 to 3.4 bar) for proper stability and handling. Incorrect tire pressure can make the cart harder to maneuver and may lead to uneven wear. Proper tire inflation ensures smooth mobility across hangar floors and ramps.

Filter replacement intervals depend on usage frequency and fluid cleanliness. For heavily used units, filters may need replacement more often, while for low-use carts, the filter element should be changed at least once annually. A clogged filter will cause increased handle resistance and prevent fluid from passing, signaling the need for replacement.

Tronair warrants its products against manufacturing or material defects for one year from the date of shipment. Replacement parts are covered for 90 days. The warranty excludes normal maintenance items, misuse, or unauthorized modifications. Any repair or return requires a Return Material Authorization (RMA) before shipment back to Tronair.

No, this cart is designed only for fluid reservoir servicing and is not intended for performing hydraulic pressure testing. Using it for testing can result in inaccurate readings, fluid contamination, or damage to both the cart and the aircraft system. Always use dedicated hydraulic test equipment for pressure checks.
