Overview
The 856A2801G04 is a high-performance, precision-engineered Fuel Pump and Hydromechanical Unit (HMU) Mounting and Removal Base Plate custom-designed for the rigorous maintenance, modular repair, and overhaul (MRO) of commercial jet engine fuel systems. Classified as a flight-critical engine-handling asset and specialized Ground Support Equipment (GSE), this ruggedized base plate is purpose-built to provide a rigid, stable, and perfectly leveled platform for the safe extraction and re-installation of heavy, high-value fuel system components. Manufactured by JUNXUN to comply with strict aerospace dimensional tolerances, the 856A2801G04 ensures absolute component alignment, preventing damaging stress on high-pressure fluid fittings, delicate mounting flanges, and electronic connector interfaces during intensive hangar servicing sequences.

Key Points
Universal Mounting Interface Alignment: Custom-machined with multi-pattern indexing pins and locking tracks compatible with standardized jet engine accessory gearbox fuel pump and HMU flange footprints.

High-Rigidity Structural Foundation: Fabricated from premium, heat-treated high-tensile alloy steel designed to provide a deflection-free, stable base that maintains perfect level alignment under the weight of high-tonnage pumps.

Integrated Fluid Containment Architecture: Features a recessed perimeter catch-basin and drainage-managed geometry to safely trap residual fuel/Skydrol during the pump un-mating process, preventing hangar floor contamination.

Non-Marring Interface Protection: Outfitted with specialized protective padding and passivated contact surfaces that shield the delicate, precision-machined flange sealing faces of the fuel pump and HMU from scratching.

Applications
Engine Fuel System Module MRO: Deployed by certified engine technicians during C-checks and D-checks to remove and re-mount fuel pumps and HMUs while ensuring zero-leak installation compliance.

Accessory Gearbox Servicing Bays: Utilized within specialized repair cells to secure heavy fuel system hardware in a fixed position, facilitating safe testing, cleaning, and inspection of internal gaskets and drive splines.

Airlines Component Overhaul Logistics: Essential specialized GSE hardware for global commercial airlines and third-party MRO facilities to drastically lower the risk of fuel system installation errors, protecting airworthiness and minimizing operational downtime.

856A2801G04 is a precision structural and interface component for aviation maintenance tools and ground support equipment, serving global narrow-body, wide-body and regional commercial aircraft fleets. Manufactured in full compliance with AS9100D aerospace quality standards and FAA/EASA safety regulations, it is precision-machined from high-strength, corrosion-resistant aerospace alloy with a hardened, anti-fatigue and anti-wear surface finish. Engineered to endure harsh airfield conditions including continuous vibration, mechanical impact, extreme temperature fluctuations and exposure to hydraulic fluid and jet fuel, it features ultra-tight dimensional tolerances and standardized mounting interfaces for direct drop-in integration. It enhances structural rigidity, load capacity and operational stability of GSE and maintenance rigs, effectively extending service life and ensuring safe, consistent performance in worldwide aircraft MRO operations.
