This genuine OEM assembly combines a robust latch mechanism, a high‑security key cylinder, and an interior release lever in a single, compact unit.
It ensures that the cab door remains firmly latched during machine operation, preventing accidental opening and protecting the operator from ejection or intrusion.
The lock assembly is manufactured from corrosion‑resistant materials and tested to withstand the harsh conditions of mining, quarrying, and construction sites.
A faulty door lock can compromise safety and security. The 802152166 lock assembly eliminates these risks with dependable, durable construction.
In XCMG articulated dump trucks, the cab door lock is a vital safety device that ensures the operator remains securely inside the cab during operation.
The 802152166 lock assembly is designed to keep the door closed against the constant vibrations and jolts experienced off‑road, preventing it from swinging open unexpectedly.
It also provides a secure barrier against unauthorized entry, protecting the machine from theft and vandalism when parked on site.
The internal release lever allows the operator to exit quickly in an emergency, while the key‑operated cylinder prevents external access without the correct key.
The lock assembly is engineered to maintain smooth operation over thousands of cycles, even in dusty or wet conditions.
The 802152166 door lock assembly is designed with a focus on durability, smooth action, and ease of installation. Its die‑cast zinc housing provides a solid foundation for the internal components.
The latch bolt is precision‑machined from high‑strength steel and zinc‑plated to resist corrosion, ensuring it engages positively with the striker plate every time.
The key cylinder uses a 4‑pin tumbler mechanism with a robust spring return, providing smooth key insertion and withdrawal even with gloved hands.
The internal release lever is ergonomically shaped and located for intuitive operation, allowing the door to be opened with a single motion.
All moving parts are protected by weather‑resistant seals that keep dust and moisture out, maintaining reliable performance over time.
The 802152166 lock assembly is built from materials chosen for their ability to withstand the corrosive effects of road salt, mud, and industrial chemicals.
The zinc alloy housing is powder‑coated with a durable, chip‑resistant finish that meets RAL 7016 (dark grey) standards.
All steel components are zinc‑plated and passivated to provide a sacrificial layer that prevents rust, even in high‑humidity environments.
The key cylinder is lubricated with a high‑temperature grease that remains effective from -30°C to +80°C, ensuring smooth operation in extreme climates.
This attention to material selection guarantees that the 802152166 lock assembly maintains its performance and appearance throughout the equipment’s service life.
The 802152166 door lock assembly is used extensively on XCMG articulated dump trucks and other heavy equipment operating in mining, quarrying, and large‑scale construction projects.
It is the primary locking mechanism for the cab door, securing the operator’s entry point and protecting the machine’s interior from weather and theft.
The lock assembly is also used on some wheel loaders and motor graders that share the same cab door design.
Its robust construction makes it suitable for applications where doors are opened and closed frequently, such as during shift changes and refueling.
The 802152166 lock assembly is designed to provide years of trouble‑free service in the toughest working conditions.
Every 802152166 door lock assembly is manufactured in an ISO 9001‑certified facility under strict quality control procedures.
Raw zinc alloy, steel, and key components are sourced from approved suppliers and tested for dimensional accuracy and material properties.
During assembly, each lock is inspected for smooth operation, latch engagement, and key cylinder function.
Finished assemblies are subjected to cycle testing (100,000 cycles) and pull‑strength testing (3000 N) to verify durability and holding force.
Salt‑spray testing per ISO 9227 confirms corrosion resistance for over 200 hours.
This comprehensive quality assurance programme guarantees that every 802152166 lock assembly meets XCMG’s stringent standards for safety and reliability.
The 802152166 door lock assembly is designed as a direct replacement for the original lock on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its mounting hole pattern (100 mm × 50 mm) matches the factory door cutouts, allowing for bolt‑on installation with the supplied hardware.
The latch throw and striker compatibility are identical to the original, ensuring proper engagement with the existing striker plate.
For cross‑brand applications, verify that the mounting dimensions and striker type are compatible.
Always consult the parts manual to confirm the correct part number for your specific machine.
Proper installation of the 802152166 door lock assembly is straightforward. Begin by removing the old lock and inspecting the door cavity for damage.
Clean the mounting surface and align the new lock with the existing holes. Insert the supplied M6 bolts and hand‑tighten them.
Close the door to check that the latch engages with the striker correctly. Adjust the lock position as needed to achieve smooth engagement.
Once correctly aligned, torque the bolts to 8‑10 N·m. Test the lock operation from both outside (with the key) and inside (with the release lever).
During routine maintenance, inspect the lock for loose bolts, wear on the latch, or difficulty in key operation.
Lubricate the key cylinder and latch pivot points with a dry graphite lubricant or light oil to maintain smooth operation. Avoid over‑lubrication to prevent attracting dust.
Replace the lock if the latch becomes worn or the cylinder jams, as this can compromise security.
