802139316 XCMG GR2605 motor grader rear wiper assembly

The XCMG GR2605 motor grader 802139316 rear wiper assembly is an integrated component for cleaning the rear view of the motor in rainy and dusty conditions. It is manufactured in strict accordance with XCMG’s original design standards, GB/T 25684.8 motor grader safety requirements, and ISO 3449 FOPS falling object protection specifications. It is specially customized for the rear window cleaning needs of the GR2605 motor grader and is perfectly adapted to extreme scenarios with high dust and mud impact, such as highway construction and maintenance, airport runway grading, open-pit mine stripping, and large-scale water conservancy earthwork filling. As an operator’s “rear view cleaning assistant,” it combines multiple functions such as miniaturized and compact wiping, low-noise and high-efficiency drive, and vibration-resistant and wear-resistant seals. It can quickly remove rainwater, mud, dust, and construction debris from the rear window glass, solving the problem of blurred rear view in bad weather. At the same time, it can resist vibration and impact and mud and water erosion in the working environment. It is a high-quality original factory replacement assembly for GR2605 grader rear wiper blades that are aging, have abnormal wiping noise, or lack drive strength, eliminating the need to purchase and piece together individual parts.

This rear wiper assembly features a miniaturized, frameless, integrated wiper structure with a custom 400mm blade length to fit the compact rear window design. It uses a composite material of natural rubber and a silicone coating, with a Shore hardness of 55-60HA. The wiping pressure is evenly distributed (0.25-0.4N/cm), ensuring 100% tight contact with the curved surface of the rear window glass, eliminating blind spots and achieving a cleaning rate of ≥97%, effectively preventing watermarks and fogging. The silicone coating reduces the coefficient of friction to below 0.12, resulting in wiping noise ≤50dB(A), providing excellent quiet operation without interfering with the driver’s cabin. The wiper blade has strong weather resistance, showing no hardening or cracking after high and low temperature cycling tests from -40℃ to 80℃, and a service life of ≥1.2 million wipes, more than 2.5 times that of ordinary small wiper blades.

The wiper drive system uses a low-noise micro DC permanent magnet motor with a rated voltage of 24V, a rated power of 40W, and an output torque of ≥8N・m. It supports single-speed adjustment (wiping frequency of 40 times/minute) and an intermittent wiping function (interval time adjustable from 8 to 20 seconds) to meet rear window cleaning needs. The motor has built-in overheat protection and overload protection devices to prevent damage caused by short circuits or mechanical jamming. It can work continuously for ≥3 hours without failure. The motor adopts an integrated package design with no exposed linkage mechanism, resulting in a compact structure. It does not loosen or jam under 25g peak vibration conditions, and the swing angle is precisely controlled at 75°±3° to ensure that the wiping range completely covers the effective field of vision of the rear window.

The wiper arm is made of high-strength aluminum alloy extrusion molding, with a surface treated by double anti-corrosion treatment of anodizing and electrostatic powder coating. Its rust resistance meets the GB/T 10125 500-hour salt spray test standard, resisting mud and water immersion and outdoor UV aging. It weighs only 60% of traditional carbon steel wiper arms, reducing motor load. The arm body features a lightweight, curved, fitted structure, and the connection to the wiper blade uses a quick-release buckle, allowing a single person to replace the wiper blade in just 8 seconds. The connection between the wiper motor and the mounting bracket is equipped with a fully enclosed EPDM (ethylene propylene diene monomer) sealed cover with an IP65 protection rating, completely preventing dust and mud from entering the internal motor and circuitry, avoiding rust, jamming, and short circuits. The cover also has a built-in shock-absorbing pad to absorb operational vibrations, further reducing operating noise.

The product’s mounting holes, motor interface, and wiper arm curvature are precisely matched 1:1 to the pre-drilled positions on the rear panel of the XCMG GR2605 original cab. The hole tolerance is controlled within ±0.03mm. The motor wiring harness interface uses the original factory standardized plug, directly connecting to the cab control circuit without additional wiring or debugging. It is secured with original factory high-strength stainless steel bolts, allowing for complete disassembly and installation by a single person. After installation, it maintains a consistent appearance with the rear panel of the cab, has a low drag coefficient, and eliminates whistling wind noise during high-speed operation. A 5-8mm safety gap is provided between the wiper arm and the edge of the rear window glass to prevent scratching the glass or sealing strip.

This rear wiper assembly has passed multiple authoritative tests and certifications: GB/T 25684.8 Safety and Performance Requirements for Grader Wipers, IP65 protection rating certification; 1.2 million wiper fatigue tests, with no blade deformation and no motor attenuation; wide temperature environment testing from -40℃ to 80℃, with normal start-up and no jamming; 500-hour salt spray + UV aging test, with no rust on metal parts and no cracking on plastic parts; noise reduction performance meets GB/T 28046.3 Noise Limits for Automotive Electrical Equipment.
