The 803164828 Flange Assembly is a critical connecting element used in the hydraulic and pneumatic systems of XCMG articulated dump trucks. It provides a robust, sealed joint between pipes, hoses, and hydraulic components, ensuring that fluid power is transmitted efficiently without leakage. The flange assembly is designed to withstand the extreme pressure spikes and mechanical vibrations typical of off-highway equipment.
Manufactured from high-quality forged steel, the flange offers superior strength and resistance to deformation. The precision-machined sealing face accepts a standard O-ring, which creates a positive seal even under fluctuating temperatures and pressures. The included mounting bolts are grade 10.9 for reliable clamping force. This genuine XCMG part is produced to the same specifications as the original flange, ensuring a perfect fit and eliminating the risk of misalignment.
Replacing a corroded or damaged flange with the 803164828 assembly restores the integrity of the hydraulic circuit, preventing costly fluid leaks and system contamination. The flange’s durable construction ensures a long service life, reducing maintenance frequency and downtime.
Whether used in steering gear connections, brake valve interfaces, or suspension accumulators, this flange assembly is an essential component for maintaining the performance and safety of your articulated dump truck.
The 803164828 flange assembly is distinguished by its forged steel construction, which offers a superior strength-to-weight ratio compared to cast alternatives. The forging process aligns the grain structure of the steel, enhancing its fatigue resistance and ability to withstand shock loads. The sealing surfaces are machined to a fine finish, ensuring optimal O-ring compression and a leak-proof seal.
The zinc plating and passivation treatment provide excellent corrosion resistance, protecting the flange from rust and chemical attack even in wet or salty environments. The included O-ring is made of nitrile rubber (NBR), which is compatible with most hydraulic fluids and offers a wide temperature range.
The flange’s bolt pattern conforms to SAE J518 and ISO 6162 standards, ensuring interchangeability with other components that use the same interface. The bolts are supplied with a consistent grade and are pre-coated with a thread locker to prevent loosening under vibration.
Each assembly is inspected for dimensional accuracy and sealing integrity, guaranteeing that it meets XCMG’s rigorous quality standards.
Replacing a worn or damaged flange with the genuine XCMG 803164828 assembly eliminates fluid leaks, which are a common cause of hydraulic system inefficiency and environmental contamination. A secure flange connection ensures that system pressure is maintained, allowing steering, braking, and suspension functions to operate at peak performance.
The flange’s robust design minimizes the risk of joint separation due to vibration or thermal expansion, reducing the likelihood of sudden failures that could lead to downtime or safety hazards. The high clamping force of the included bolts ensures that the O-ring remains compressed, providing a reliable seal over the entire service interval.
By preventing leaks, the flange assembly also reduces fluid consumption and the need for frequent top-ups, lowering operational costs. The corrosion-resistant coating extends the flange’s life in harsh environments, reducing replacement frequency and associated labor costs.
Overall, the 803164828 flange assembly contributes to improved machine reliability, reduced maintenance, and enhanced safety on the job site.
The 803164828 flange assembly is used extensively in the hydraulic systems of XCMG articulated dump trucks, including DA30, DA40, XDA40, and DA45 models. It is commonly found at the connection points between hydraulic hoses and rigid tubes, such as at the steering pump outlet, brake valve inlet, and suspension accumulator ports.
In steering circuits, the flange ensures a leak-free connection between the hydraulic pump and the steering gear, providing responsive and accurate steering control. In braking systems, it secures the lines from the master cylinder to the brake actuators, maintaining brake pressure for safe stopping.
The flange is also used in suspension systems to connect the height control valves to the accumulators, allowing for dynamic load leveling. Its versatility makes it suitable for a wide range of fluid power applications, both original and aftermarket.

XCMG applies rigorous quality control to the production of the 803164828 flange assembly. The raw steel is sourced from certified mills and undergoes chemical analysis to confirm its composition. The forging process is carefully monitored to ensure consistent grain flow and mechanical properties.
After machining, each flange is inspected for dimensional accuracy using coordinate measuring machines. The sealing surface flatness and roughness are verified to ensure proper O-ring sealing. The plating thickness is measured to confirm corrosion protection.
The O-rings are tested for hardness, tensile strength, and compression set to guarantee long-term sealing performance. The bolts are sampled for tensile strength and hardness. Only assemblies that pass all inspections are released for sale, providing customers with consistent quality and reliability.
With XCMG’s commitment to excellence, the 803164828 flange assembly delivers long-lasting performance in the most demanding conditions.
Installing the 803164828 flange assembly is a straightforward procedure. Begin by ensuring that the mating surfaces are clean and free of debris. Place the O-ring in the groove on the flange, then align the flange with the port or tube end. Insert the bolts and tighten them evenly in a cross-pattern to the recommended torque of 35–40 N·m.
After installation, pressurize the system and check for leaks. If any leakage is detected, re-tighten the bolts slightly, but avoid over-torquing, which could damage the flange or O-ring. Periodically inspect the flange for signs of corrosion, cracking, or bolt loosening.
When replacing the flange, always use new O-rings and bolts to ensure a proper seal. The flange itself is reusable if undamaged, but inspect the sealing surfaces for scratches or pitting. Replace the assembly if any damage is found.
Following these guidelines will ensure long-lasting, leak-free connections.
