The 802155643 Wiper Arm is a genuine XCMG heavy‑duty windshield wiper arm engineered to provide reliable, consistent blade pressure and smooth sweeping motion for articulated dump trucks and large mining machines. This OEM wiper arm, identified by part number 802155643, is manufactured from high‑strength steel with a durable corrosion‑resistant coating, and features a precision‑engineered pivot joint and spring‑loaded tension mechanism. Designed to withstand the extreme vibration, dust, mud, and temperature fluctuations of surface and underground mining, the 802155643 wiper arm ensures that the wiper blade maintains optimal contact with the windshield, delivering streak‑free clearing and uncompromised visibility for the operator.
The 802155643 Wiper Arm is a critical component of the windshield wiper system, responsible for translating the motor’s rotational motion into the sweeping action that clears the glass.
This genuine XCMG arm is designed to provide consistent, even pressure across the entire length of the wiper blade, ensuring that the entire swept area is cleaned effectively.
The arm’s robust construction, featuring a heavy‑duty spring and precision pivot, resists the bending and fatigue that can occur in cheaper aftermarket parts, especially in high‑vibration environments.
Its corrosion‑resistant coating protects against the rust and pitting that can seize the pivot joint, ensuring smooth operation for years.
A worn or bent wiper arm can cause streaking, chattering, or incomplete clearing. The 802155643 arm eliminates these issues with reliable, long‑lasting performance.
In XCMG articulated dump trucks, the wiper arm is the link between the wiper motor and the blade, and its condition directly affects the quality of the wipe.
The arm must maintain precise alignment and pressure to ensure the blade conforms to the windshield’s curvature, especially on large, curved glass surfaces.
If the arm’s spring loses tension, the blade will lift off the glass at high speeds, leaving unwiped areas that obscure the operator’s view.
Conversely, if the arm is bent, it may press the blade too hard, causing premature wear and excessive drag on the motor.
The 802155643 arm is engineered to provide the optimal balance of pressure and flexibility, ensuring reliable performance throughout the wipe cycle.
The 802155643 wiper arm is fabricated from high‑grade spring steel, chosen for its excellent fatigue resistance and ability to maintain tension over millions of cycles.
The arm is precision‑formed using computer‑controlled bending equipment, ensuring that the curvature and length match the OEM specifications exactly.
The pivot joint incorporates a self‑lubricating bronze bushing that reduces friction and wear, ensuring smooth oscillation without play.
The spring tension is factory‑set and tested to provide uniform pressure across the blade’s entire length, compensating for minor windshield irregularities.
The arm’s hook‑end blade attachment is compatible with the most common blade connector types, allowing easy blade replacement without special tools.
The 802155643 wiper arm is manufactured using a multi‑stage corrosion protection process to ensure longevity in the harsh environments typical of mining and construction.
After forming, the arm is zinc electroplated to provide a sacrificial layer that resists rust, then coated with a durable black epoxy powder finish.
The spring is individually oil‑tempered and coated with a corrosion‑inhibiting oil that protects it from moisture and airborne chemicals.
All pivot hardware is made from stainless steel or zinc‑plated steel, preventing seizing and ensuring that the arm can be easily adjusted or removed when needed.
This comprehensive protection ensures that the 802155643 wiper arm maintains its appearance and functionality even after years of exposure to mud, rain, and road salt.
The 802155643 wiper arm is used extensively on XCMG articulated dump trucks and other heavy equipment in surface mining, underground mining, and large‑scale construction projects.
It is a direct replacement for the original arm on the cab’s windshield wiper system, ensuring that the blade maintains optimal contact with the glass.
The arm is also compatible with some wheel loaders, excavators, and motor graders that share the same wiper arm design.
Its robust construction makes it particularly suitable for use in dusty underground mines where visibility is critical, and in open‑pit mines where heavy rain and mud are common.
By ensuring clear, streak‑free wiping, the 802155643 wiper arm helps operators maintain a safe view of haul roads, loading equipment, and personnel.
Every 802155643 wiper arm is manufactured in an ISO 9001‑certified facility under strict quality control measures.
Incoming steel coil is tested for chemical composition, hardness, and tensile strength to ensure it meets the required specifications.
During forming, each arm is inspected for dimensional accuracy, spring tension, and pivot smoothness using precision gauges and force‑measuring equipment.
Finished arms undergo a 100% functional check, including a wipe‑pattern test on a test windshield to verify pressure distribution and sweep geometry.
Salt‑spray testing per ISO 9227 confirms corrosion resistance for over 300 hours, while vibration testing simulates real‑world operating conditions.
This comprehensive quality assurance programme guarantees that every 802155643 wiper arm meets XCMG’s exacting standards for performance and durability.
The 802155643 wiper arm is designed as a direct replacement for the original arm on XCMG articulated dump trucks, including models XDA30, XDA40, XDA45, XDA45U, XDA60, TA30, AD45, AD60, and other variants.
Its splined or D‑shaped pivot shaft matches the wiper motor output, ensuring correct orientation and secure attachment.
The hook‑end blade attachment is compatible with most standard 6.35 mm (¼ inch) blade connectors, allowing the use of common replacement blades.
For cross‑brand applications, verify that the pivot shaft diameter, spline count, and arm length are compatible with your specific wiper system.
Always consult the parts manual to confirm the correct part number for your machine.
Proper installation of the 802155643 wiper arm is straightforward. Begin by lifting the old arm away from the windshield and removing the retaining nut from the pivot shaft.
Gently rock the arm back and forth while pulling it upward to detach it from the splined shaft. Clean the shaft and apply a light coating of anti‑seize compound.
Position the new arm over the shaft, aligning the splines, and push it down until it seats fully. Install the retaining nut and torque to 20‑25 N·m.
Attach the wiper blade to the hook end, ensuring it clicks securely into place. Lower the arm to the windshield and check the blade’s angle; it should be perpendicular to the glass.
Run the wiper through a full cycle to verify that the blade sweeps the correct area without hitting the frame or leaving unwiped edges.
During routine maintenance, inspect the arm for bending, corrosion, or loss of spring tension. Replace the arm if the blade no longer contacts the glass evenly.
Lubricate the pivot joint with a silicone‑based grease annually to maintain smooth operation.
The 802155643 wiper arm complies with SAE J903, which sets performance and durability requirements for windshield wiper systems used in off‑highway vehicles.
