The 801738602 Spring is a genuine XCMG heavy‑duty compression spring engineered to provide reliable force and cushioning in articulated dump truck suspension, brake, and tensioning systems. This OEM spring, identified by part number 801738602, is precision‑wound from high‑grade alloy steel and heat‑treated to deliver consistent spring rates, exceptional fatigue resistance, and minimal set. Designed to withstand the extreme loads and repetitive cycling typical of mining and construction operations, the 801738602 spring ensures stable ride height, proper brake shoe retraction, and consistent tension in mechanical linkages.
The 801738602 Spring is a precision‑engineered compression spring that provides critical force and energy absorption in XCMG articulated dump trucks and heavy equipment.
This genuine OEM spring is designed to maintain consistent ride height, absorb impact loads, and return mechanical components to their neutral positions.
Manufactured from high‑strength chrome‑silicon steel, the spring offers superior resistance to fatigue, permanent set, and corrosion.
Its precise wire diameter, coil pitch, and end geometry ensure that it delivers the specified spring rate over its entire deflection range.
A broken or sagging spring compromises ride quality, handling, and component life. The 801738602 spring eliminates these risks with reliable, long‑lasting performance.
In XCMG articulated dump trucks, springs are used in suspension struts to support the chassis and isolate the cab from road shocks and vibrations.
The 801738602 spring is typically installed in the front suspension assembly, where it carries a significant portion of the vehicle’s static and dynamic loads.
Without a properly functioning spring, ride height drops, bottoming out occurs, and steering stability is compromised, increasing the risk of rollover.
Additionally, the spring is used in brake shoe return mechanisms and clutch release systems, where it ensures rapid disengagement and prevents drag.
The 801738602 spring is engineered to withstand the extreme static and dynamic loads encountered in mining and construction operations, ensuring consistent performance and safety.
The 801738602 spring features a precision‑wound helical geometry with closed and ground ends that provide a flat seating surface and prevent stress concentration at the ends.
The wire is cold‑wound from high‑grade chrome‑silicon steel (SAE 9254), which offers an optimal balance of strength, ductility, and fatigue resistance.
After winding, the spring undergoes stress‑relief heat treatment to eliminate residual stresses and improve dimensional stability.
The shot‑peening process induces compressive residual stresses on the surface, significantly enhancing fatigue life and resistance to stress corrosion cracking.
A phosphate coating provides a protective layer against corrosion and wear, extending service life in aggressive environments.
The 801738602 spring is manufactured from premium alloy steel containing chromium, silicon, and vanadium, which impart exceptional hardenability and resistance to tempering.
The wire is quenched and tempered to achieve a tensile strength of approximately 1850 MPa, delivering a high strength‑to‑weight ratio.
This material retains its elasticity at temperatures up to 120°C and maintains its spring rate within ±3% of nominal over the entire operating range.
The controlled grain structure ensures consistent deformation behavior and prevents premature failure due to micro‑cracking.
Advanced material science guarantees that the 801738602 spring delivers reliable performance under the most demanding conditions.
The 801738602 spring is used extensively in XCMG articulated dump trucks operating in surface mining, underground mining, and large‑scale infrastructure projects.
It is commonly found in front and rear suspension strut assemblies, where it provides the primary load‑carrying capability and controls ride height.
The spring is also used in brake shoe return mechanisms, ensuring rapid brake release and preventing drag that can cause overheating and premature wear.
In clutch and power‑take‑off systems, the spring provides the necessary force for engagement and disengagement.
The 801738602 spring is also suitable for other XCMG equipment, including wheel loaders and motor graders that use compatible spring dimensions.
Every 801738602 spring is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Raw wire is sourced from approved mills and tested for chemical composition, tensile strength, and dimensional tolerance before production.
During winding, each spring is inspected for coil pitch, outer diameter, free length, and end flatness using precision gauges.
Finished springs undergo 100% load testing at specified deflection points to verify spring rate and load capacity.
Fatigue testing is performed on representative samples to confirm a minimum life of 8 million cycles, ensuring long‑term reliability.
This comprehensive quality assurance programme guarantees that every 801738602 spring meets XCMG’s exacting standards for durability and performance.
The 801738602 spring is designed as a direct replacement for the original spring on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, and AD60.
The spring’s dimensions and spring rate exactly match the OEM specifications, ensuring proper ride height, load capacity, and damping characteristics.
When replacing a sagging or broken spring, using the genuine 801738602 restores the suspension to factory performance levels.
For cross‑brand applications, verify that the spring’s free length, outer diameter, wire diameter, and rate match your equipment’s requirements.
Always consult the parts manual to confirm the correct part number for your specific machine.
Proper installation of the 801738602 spring is essential for safe and reliable operation. Before installation, inspect the spring for any signs of damage, including cracks, rust, or deformation.
Ensure that the spring seats and mounting surfaces are clean and free from debris, and that any worn or damaged rubber insulators are replaced.
Use a suitable spring compressor to safely compress the spring during installation, following all manufacturer safety guidelines.
Position the spring with its closed ends oriented toward the seats to ensure proper load distribution and avoid point loading.
Torque all mounting fasteners to the specified values and lower the vehicle slowly, checking for any binding or misalignment.
During routine maintenance, inspect the spring for signs of corrosion, cracking, or loss of free height. Replace immediately if any damage is observed.
Regularly check ride height and suspension alignment to ensure proper spring function.
The 801738602 spring complies with international standards including SAE J1179 (coil spring specifications) and DIN 2095 (helical compression springs).
It meets the requirements for fatigue life, load capacity, and dimensional accuracy specified for heavy‑duty off‑highway applications.
The materials used are free from restricted substances such as lead, cadmium, and hexavalent chromium.
This ensures that the spring is safe for operators and environmentally responsible.
Using genuine XCMG springs like the 801738602 also helps maintain compliance with equipment warranty and safety regulations.
