This OEM assembly, identified by part number 860641663, features high‑strength steel tubing with precision‑welded brackets, a durable corrosion‑resistant powder‑coat finish, and integrated guide sleeves that allow smooth height adjustment of the headrest cushion. Designed to withstand the extreme vibration, shock loads, and harsh environmental conditions of surface and underground mining, the 860641663 headrest tube assembly delivers reliable structural integrity, operator comfort, and long service life, making it an essential replacement component for maintaining seat functionality, operator well‑being, and workplace safety in the most demanding working environments.
The 860641663 Headrest Tube Assembly is the structural backbone of the operator seat headrest, providing robust support for the cushion and enabling height adjustment.
This genuine XCMG component is designed to withstand the continuous vibration, shock loads, and heavy use typical of mining and construction equipment.
Its high‑strength steel tubing and precision‑welded brackets ensure that the headrest remains securely attached to the seat frame, providing reliable support.
The integrated guide sleeves allow smooth, positive height adjustment, enabling operators to position the headrest for optimal comfort and support.
This component is a direct OEM replacement, restoring the original headrest functionality and seat ergonomics.
Regular inspection of the tube assembly for cracks, corrosion, or bent tubes is recommended; replace immediately if any damage is detected.
A properly functioning headrest is essential for operator comfort and neck protection, particularly during long shifts and in the event of sudden stops or impacts.
The 860641663 tube assembly provides the structural support needed to keep the headrest cushion in the correct position, reducing the risk of whiplash injuries.
Adjustable height allows operators of different statures to position the headrest for optimal head and neck support, reducing fatigue and discomfort.
A damaged or loose headrest tube can cause the headrest to wobble or collapse, compromising both comfort and safety.
Replacing a faulty tube assembly with a genuine XCMG unit restores the original headrest stability and protection.
The 860641663 headrest tube assembly is engineered with a focus on structural strength, smooth adjustability, and long‑term durability.
The steel tubing is manufactured to precise dimensions, with a wall thickness of 2.0 mm that provides excellent strength‑to‑weight ratio.
All welded joints are robotically welded and inspected for full penetration, ensuring maximum structural integrity under dynamic loads.
The guide sleeves are precision‑machined to provide a snug, low‑friction fit that allows smooth height adjustment while eliminating rattles and play.
Positive detent positions are incorporated into the adjustment mechanism, providing clear tactile feedback and secure locking at each height setting.
The mounting bracket is designed with reinforced gussets to resist bending and fatigue, ensuring long‑term reliability.
The 860641663 headrest tube assembly is constructed from materials selected for their ability to withstand the harsh conditions of mining and construction.
The carbon steel tubing is sourced from approved mills and tested for chemical composition and mechanical properties.
The black epoxy powder coating provides a tough, abrasion‑resistant finish that protects against rust, chemicals, and UV degradation, with salt‑spray resistance exceeding 300 hours.
All hardware, including mounting bolts and clips, is zinc‑plated to resist corrosion and ensure easy removal during maintenance.
The assembly is designed to perform reliably in temperatures from -40°C to +85°C, making it suitable for both arctic and tropical climates.
The 860641663 headrest tube assembly is used extensively on XCMG articulated dump trucks, wheel loaders, excavators, and motor graders across surface and underground mining operations.
It is installed on the seat backrest frame, supporting the headrest cushion and enabling height adjustment for operator comfort.
In multi‑shift operations, the adjustment feature allows different operators to position the headrest to their individual requirements.
Its robust construction makes it suitable for use in both surface and underground environments, where dust, moisture, and temperature extremes are prevalent.
By using genuine XCMG headrest tube assemblies, operators ensure consistent seat comfort and safety performance.
Every 860641663 headrest tube assembly is manufactured in an ISO 9001 and ISO 14001 certified facility, with full material traceability and process control.
Incoming steel tubing, brackets, and hardware are tested for dimensional accuracy, mechanical properties, and coating adhesion.
During welding, each joint is visually inspected and subjected to non‑destructive testing to verify weld integrity.
Completed assemblies undergo a 100% functional test, including height adjustment smoothness, detent engagement, and load capacity verification.
A sample from each batch is subjected to fatigue testing (100,000 cycles) and salt‑spray exposure to validate long‑term durability.
Only assemblies that pass all tests are released, guaranteeing consistent quality and reliability.
The 860641663 headrest tube assembly is a direct replacement for the original component on XCMG articulated dump trucks, including XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, and many other models.
It is also compatible with various XCMG wheel loaders, excavators, and motor graders that use the same headrest mounting system.
The mounting bracket hole spacing and tube diameter match the original equipment, ensuring a straightforward installation.
For cross‑brand applications, verify that the mounting dimensions and headrest cushion attachment method are compatible.
Always consult your machine’s parts manual to confirm the correct part number before ordering.
Installing the 860641663 headrest tube assembly requires basic hand tools. Begin by removing the old assembly from the seat backrest.
Clean the mounting area and inspect the seat frame for any damage. Position the new tube assembly on the seat frame, aligning the bracket holes.
Secure the bracket using the M8 bolts, torqued to 18‑22 N·m. Ensure the tube is vertical and does not bind.
Attach the headrest cushion to the tube, pressing it firmly until the retaining clips engage securely. Adjust the height to verify smooth operation and detent locking.
During routine inspections, check the tube for bends, cracks, or corrosion. Verify that the height adjustment mechanism operates smoothly and locks positively.
Replace the assembly immediately if any signs of wear or damage are detected. Keep a spare unit on hand to minimise downtime.
