The 802164442 Flexible Coupling is a critical driveline component that transmits torque from the transmission to the driveline while accommodating misalignment and damping vibration.
This genuine XCMG coupling is engineered to protect connected equipment from shock loads and torsional oscillations, extending the service life of the entire powertrain.
Its robust elastomeric element provides excellent flexibility and resilience, ensuring smooth power delivery even under heavy loads and harsh operating conditions.
The precision‑machined steel hubs are zinc‑plated for corrosion resistance and feature standard keyways for secure shaft attachment.
Included high‑strength bolts and nuts ensure a reliable, maintenance‑free connection when installed with correct torque.
Regular inspection of the coupling for wear, cracking, or loose fasteners is essential for continued drivetrain reliability.
In heavy equipment, driveline components are subjected to continuous torque fluctuations, shock loads, and shaft misalignment that can cause premature failure of bearings, gears, and seals.
A flexible coupling absorbs these stresses, reducing the impact on connected components and preventing costly damage.
The 802164442 coupling’s elastomeric element is specifically formulated to resist oil, heat, and aging, ensuring consistent performance over thousands of operating hours.
By replacing worn or damaged couplings promptly, operators avoid unplanned downtime and extend the life of their drivetrain.
This coupling is a direct OEM replacement, restoring the original protection and performance of the vehicle’s driveline system.
The 802164442 flexible coupling is engineered with a focus on torque capacity, misalignment accommodation, and long‑term durability.
The rubber element is bonded to the steel hubs under high pressure, creating a secure, seamless connection that prevents separation under extreme loads.
The hub geometry is designed to distribute stress evenly, reducing the risk of fatigue failure in both the coupling and the connected shafts.
Precision‑machined bores and keyways ensure a snug fit on shafts, minimising fretting and wear.
The coupling’s compact design allows for easy installation in tight engine compartments without sacrificing performance.
All fasteners are supplied with pre‑applied thread‑locking compound to prevent loosening under vibration.
The 802164442 coupling is constructed from materials selected for their ability to withstand the harsh conditions of mining and construction.
The steel hubs are cast from high‑strength SC450 steel, offering excellent tensile strength and impact resistance.
The zinc plating and black epoxy overcoat provide superior corrosion protection, withstanding over 300 hours of salt spray testing.
The elastomer is a proprietary natural rubber compound with added antioxidants and anti‑ozonants, ensuring long life in high‑temperature, high‑humidity environments.
All materials are RoHS compliant and free from hazardous substances.
The 802164442 flexible coupling is used extensively on XCMG articulated dump trucks, wheel loaders, and other equipment that rely on robust driveline connections.
It is typically installed between the transmission output shaft and the driveline, or between the driveline and the axle input, providing both torque transmission and misalignment compensation.
The coupling is also used in auxiliary drives, such as pump drives and fan drives, where vibration isolation is required.
Its robust design makes it suitable for both surface and underground mining applications, where shock loads and dust are prevalent.
By maintaining a reliable coupling, operators ensure smooth power delivery and reduce the risk of drivetrain failures.
Every 802164442 flexible coupling is manufactured in an ISO 9001 and ISO 14001 certified facility, with full traceability of materials and processes.
Incoming steel castings are inspected for chemical composition and mechanical properties; rubber batches are tested for hardness, tensile strength, and adhesion.
During assembly, each coupling is dynamically balanced to ensure smooth operation at high speeds.
Finished couplings undergo a 100% torque test and misalignment check to verify performance against specifications.
Samples from each batch are subjected to fatigue testing, salt‑spray exposure, and temperature cycling to validate long‑term reliability.
Only couplings that pass all tests are released for sale, ensuring consistent quality and performance.
The 802164442 flexible coupling is a direct replacement for the original coupling on XCMG articulated dump trucks, including XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and many other models.
It is also compatible with various XCMG wheel loaders, motor graders, and other equipment that use the same coupling design.
The coupling’s bore sizes and keyways match the standard shaft dimensions of these machines, ensuring a drop‑in installation.
For cross‑brand applications, verify that the hub bores, keyway sizes, and overall dimensions match your existing coupling.
Always consult your machine’s parts manual to confirm the correct part number before ordering.
Installing the 802164442 flexible coupling requires mechanical skill and adherence to torque specifications. Begin by disconnecting the driveline and removing the old coupling.
Inspect the shafts for wear or damage; clean the bores and keyways of any debris or burrs. Apply a light coating of anti‑seize compound to the shaft surfaces.
Install the hubs onto their respective shafts, ensuring the keyways align and the hubs are fully seated. Tighten the shaft set screws (if applicable) to the recommended torque.
Position the elastomeric element between the hubs and insert the M12 bolts through the assembly. Tighten the bolts evenly in a cross‑pattern to the specified torque (80‑90 N·m).
Check the alignment and runout using a dial indicator; adjust as necessary. Reconnect the driveline and test for smooth operation.
During routine maintenance, inspect the coupling for cracks in the rubber, wear on the hubs, and loose fasteners. Replace the coupling if any damage is detected or if the rubber shows signs of aging.
The 802164442 flexible coupling complies with SAE J620, which outlines performance requirements for flexible couplings used in off‑road machinery.
It is manufactured in accordance with ISO 9001 quality management and ISO 14001 environmental standards.
