The 802141159 Shock Absorber is a genuine XCMG hydraulic damper engineered to provide superior ride control and stability for articulated dump trucks operating in the most demanding off‑road conditions. This OEM shock absorber, identified by part number 802141159, features a high‑performance monotube or twin‑tube design with precision‑valved damping, ensuring consistent force over a wide temperature range. Manufactured from heavy‑walled steel with a durable corrosion‑resistant finish, the 802141159 shock absorber effectively controls spring oscillations, reduces tyre hop, and maintains traction, enhancing both operator comfort and machine productivity.
The 802141159 Shock Absorber is a precision‑engineered hydraulic damper that provides critical ride control for XCMG articulated dump trucks, ensuring stability and safety on uneven terrain.
This genuine OEM shock absorber is designed to convert kinetic energy from spring oscillations into thermal energy, dissipating it through a controlled hydraulic circuit.
Its advanced valving system delivers consistent damping forces across a wide range of operating speeds and temperatures.
The robust steel body and piston rod are treated for corrosion resistance, ensuring reliable performance in the harsh mining and construction environments.
A worn or leaking shock absorber can lead to excessive body roll, poor traction, and reduced operator comfort. The 802141159 shock absorber eliminates these risks with dependable, long‑lasting performance.
In XCMG articulated dump trucks, shock absorbers are essential for controlling the motion of the springs, preventing the vehicle from bouncing or rolling excessively after encountering bumps.
The 802141159 shock absorber is typically installed at each wheel corner, working in conjunction with heavy‑duty coil or leaf springs to dampen vertical oscillations.
Without adequate damping, the vehicle’s tyres lose contact with the ground, reducing traction and braking effectiveness, especially on loose surfaces.
The shock also protects suspension components from impact loads, extending the life of bushings, ball joints, and spring mounts.
The 802141159 shock absorber is engineered to withstand the high energy inputs typical of off‑highway haulage, ensuring consistent control and safety.
The 802141159 shock absorber features a monotube (or high‑performance twin‑tube) design with a floating piston that separates the oil from the high‑pressure nitrogen gas, preventing aeration and maintaining consistent damping.
The piston is fitted with precision‑engineered valve discs and shims that control oil flow during both rebound and compression strokes, providing a digressive damping curve that offers firm control without sacrificing ride quality.
The outer body is manufactured from heavy‑wall seamless steel tubing, precision‑machined to ensure tight tolerances and a long seal life.
The piston rod is induction‑hardened and chrome‑plated to resist scoring and corrosion, ensuring smooth operation and a leak‑free seal.
All seals are made from high‑temperature fluorocarbon compounds that resist hydraulic oil degradation and maintain flexibility over a wide temperature range.
The 802141159 shock absorber’s valving is tuned specifically for the weight and suspension geometry of XCMG articulated dump trucks, providing optimal balance between ride comfort and load control.
The damping force increases progressively with shaft velocity, offering low‑speed compliance for minor road irregularities and high‑speed firmness for large impacts.
The compression stroke is designed to be softer than the rebound stroke, allowing the tyre to absorb bumps while controlling spring rebound to keep the tyre planted.
The gas‑charged design also eliminates cavitation, ensuring consistent damping even after repeated high‑frequency cycling.
This results in improved handling, reduced driver fatigue, and longer tyre life.
The 802141159 shock absorber is widely used in XCMG articulated dump trucks operating in surface mining, underground mining, and heavy construction sites.
It is installed on all four corners of the vehicle to control the oscillation of the suspension springs, ensuring stability on uneven haul roads.
The shock absorber is also used in the rear suspension of rigid and articulated haulers to reduce axle hop and improve traction.
In high‑tonnage applications, the shock’s robust construction ensures it can handle the enormous energy generated by heavy loads and rough terrain.
The 802141159 shock absorber is also suitable for other XCMG equipment, including wheel loaders and motor graders, where suspension damping is critical.
Every 802141159 shock absorber is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Raw steel tubes, piston rods, and seals are sourced from approved suppliers and tested for dimensional accuracy and material properties.
During assembly, each shock is filled with precisely measured hydraulic fluid and charged with nitrogen gas to the correct pressure.
Finished units undergo 100% dynamometer testing to verify damping force at multiple velocities and stroke positions, ensuring they meet the specified curve.
Leak tests and durability cycling (over 1 million cycles) are performed on sample units to guarantee reliability.
This comprehensive quality assurance programme ensures that every 802141159 shock absorber delivers consistent performance throughout its service life.
The 802141159 shock absorber is designed as a direct replacement for the original damper on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its eye‑eye mounting configuration with 20 mm bushings matches the factory brackets, ensuring a bolt‑on installation without modification.
The extended and compressed lengths (620/420 mm) are identical to OEM specifications, maintaining proper suspension travel and bump‑stop clearance.
For cross‑brand applications, verify that the stroke, length, and mounting dimensions are compatible with your specific axle and frame.
Always consult the parts manual to confirm the correct part number for your machine.
Proper installation of the 802141159 shock absorber is critical for safety and performance. Always replace shock absorbers in pairs (front or rear) to ensure balanced damping.
Before installation, inspect the mounting bolts, bushings, and brackets for wear or damage. Replace any worn components.
Use a suitable jack to support the axle, then remove the old shock by loosening the retaining bolts. Compress the new shock slightly to align the eyelets with the mounting pins.
Install the new shock absorber with the rubber bushings and washers, and torque the bolts to the manufacturer’s specification (typically 120‑150 N·m for M14 bolts).
Lower the vehicle and test the suspension by bouncing the vehicle to ensure the shock operates smoothly without binding.
During routine maintenance, inspect the shock for oil leaks, damaged dust covers, or bent rods. If any signs of wear are present, replace the shock immediately.
Regularly check the torque of the mounting bolts as part of the preventive maintenance schedule.
The 802141159 shock absorber complies with SAE J1850, which covers performance requirements for shock absorbers used in off‑highway equipment.
It also meets ECE R90 standards for replacement shock absorbers, ensuring that its performance matches or exceeds the original equipment.
The materials used are free from restricted substances, complying with RoHS and REACH regulations.
Using genuine XCMG shock absorbers like the 802141159 helps maintain compliance with equipment warranty and safety regulations.
Aftermarket shock absorbers may be cheaper, but they often use inferior valving, thinner tubes, or low‑quality seals that lead to premature failure and poor ride control.
