The 804044664 Suspension Cylinder is a precision hydraulic damper that provides essential ride control and load support on XCMG articulated dump trucks.
This genuine XCMG cylinder is engineered to absorb road shocks and maintain wheel contact, improving machine stability and operator comfort.
Its robust construction, featuring a hardened chrome‑plated rod and heavy‑duty seals, ensures reliable performance in dusty, wet, and high‑vibration mining environments.
The cylinder’s double‑acting design provides controlled damping in both compression and rebound strokes, ensuring a smooth ride over rough terrain.
This component is a direct OEM replacement, restoring the original suspension characteristics and ride quality.
Regular inspection of the cylinder for leaks, rod scoring, or seal wear is essential for maintaining optimal ride performance.
The suspension system of an articulated dump truck is responsible for isolating the chassis and operator from road impacts, ensuring stability and reducing operator fatigue.
The 804044664 cylinder works in conjunction with hydropneumatic accumulators to provide a spring‑and‑damper effect, smoothing out bumps and maintaining tyre contact.
A worn or leaking suspension cylinder can cause excessive body roll, poor handling, and increased tyre wear, compromising safety and productivity.
Properly functioning suspension cylinders reduce shock loads on the chassis and drivetrain, extending the life of other components.
Replacing a failing cylinder with a genuine XCMG unit restores the original ride quality and stability, enhancing operator confidence and machine control.
The 804044664 suspension cylinder is engineered with a focus on damping performance, durability, and smooth operation.
The cylinder body is manufactured from high‑strength steel tubing with a zinc‑nickel plating that provides excellent corrosion resistance and protection against abrasion.
The piston rod is induction‑hardened and hard‑chrome plated to provide a wear‑resistant, low‑friction surface that extends seal life and reduces scoring.
The piston features dual polyurethane U‑cup seals with integral wear rings that prevent metal‑to‑metal contact and maintain efficient sealing even under side loading.
The rod seal assembly includes a primary lip seal and a wiper that removes contaminants from the rod during retraction, protecting the internal components from dirt and moisture.
All fittings and pins are zinc‑plated for corrosion resistance, ensuring easy disassembly during maintenance.
The 804044664 cylinder is constructed from materials selected for their ability to withstand the corrosive and abrasive conditions of mining and construction.
The steel body is zinc‑nickel plated, providing a robust barrier against rust and chemical attack, with salt‑spray resistance exceeding 300 hours.
The chrome plating on the rod is applied to a minimum thickness of 50 µm, ensuring long‑lasting protection against corrosion and mechanical wear.
The polyurethane seals are formulated to resist abrasion, extrusion, and chemical degradation from hydraulic oils, maintaining sealing integrity over a wide temperature range.
All fasteners and pins are zinc‑plated or coated with anti‑corrosion treatments to prevent seizing and ensure easy removal.
The 804044664 suspension cylinder is used extensively on XCMG articulated dump trucks in surface mining, underground mining, and large‑scale construction projects.
It is a critical component of the front and rear suspension systems, providing damping and load support to maintain vehicle stability on uneven terrain.
In addition to articulated dump trucks, this cylinder is also used in XCMG wheel loaders and motor graders that feature hydropneumatic suspension systems.
Its robust design makes it suitable for use in both surface and underground environments, where dust, moisture, and temperature extremes are prevalent.
Reliable suspension performance is essential for maintaining operator comfort, reducing fatigue, and maximising productivity during long shifts.
Every 804044664 suspension cylinder is manufactured in an ISO 9001 and ISO 14001 certified facility, with full material traceability and process control.
Incoming steel tubing, rod material, and seal components are tested for dimensional accuracy, hardness, and material composition.
During assembly, each cylinder is subjected to a 100% leak test at 1.5 times the working pressure, followed by a function test to verify damping characteristics throughout the full stroke.
A sample from each production batch is endurance‑tested for over 200,000 cycles to validate seal life and mechanical integrity.
All cylinders are visually inspected for surface finish, plating quality, and proper assembly before packaging.
Only cylinders that pass all tests are released, guaranteeing consistent performance and reliability.
The 804044664 suspension cylinder is a direct replacement for the original cylinder on XCMG articulated dump trucks, including XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, and many other models.
It is also compatible with select XCMG wheel loaders and motor graders that use the same suspension cylinder design.
The cylinder’s mounting dimensions, port sizes, and pin diameters are matched to the original equipment, ensuring a hassle‑free installation.
For cross‑brand applications, verify that the stroke length, bore size, and mounting type match your requirements.
Always consult your machine’s parts manual to confirm the correct part number before ordering.
Replacing the 804044664 suspension cylinder requires mechanical skills and standard hand tools. Always support the axle or chassis securely before removing the cylinder.
Depressurise the hydraulic system and disconnect the supply and return lines from the cylinder ports. Cap the lines to prevent fluid loss and contamination.
Remove the mounting pins securing the cylinder to the axle and chassis, and carefully remove the old cylinder.
Install the new cylinder in reverse order, ensuring the pins are fully seated and secured with retaining clips.
Reconnect the hydraulic lines, tighten the fittings to the recommended torque, and bleed the system to remove trapped air.
Cycle the suspension through its full range to verify smooth operation and check for leaks. Re‑torque fittings after the first test cycle.
During routine maintenance, inspect the cylinder for oil leaks, rod scoring, or damage. Replace the cylinder if any signs of wear or damage are detected.
The 804044664 suspension cylinder complies with ISO 6020/2, which specifies mounting dimensions and performance requirements for hydraulic cylinders.
It is manufactured in accordance with ISO 9001 quality management and ISO 14001 environmental standards.
The cylinder is CE marked and RoHS compliant, meeting international safety and environmental regulations.
Using genuine XCMG cylinders ensures compliance with original equipment safety specifications, including load‑holding and damping requirements.
