802139315 XCMG GR2605 motor grader front wiper assembly

802139315 XCMG GR2605 motor grader front wiper assembly

The XCMG GR2605 motor grader 802139315 front wiper assembly is a core integrated component for cleaning the windshield of the machine 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 windshield cleaning needs of the GR2605 motor grader and is perfectly adapted to extreme scenarios with high dust, mud and water impact, and concentrated rainy operations, such as highway construction and maintenance, airport runway grading, open-pit mine stripping, and large-scale water conservancy earthwork filling. As a “vision cleaner” for operators, it combines multiple functions such as frameless tight wiping, quiet and efficient drive, and vibration-resistant and wear-resistant sealing. It can quickly remove rainwater, mud, dust and construction debris from the windshield, solving the problem of blurred vision 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 motor grader wiper blade aging, abnormal wiping noise, weak drive and linkage jamming, without the need to purchase and assemble parts piece by piece.

This front wiper assembly features a frameless integrated wiper structure with a custom-designed 650mm blade length. It utilizes a composite material of natural rubber and graphite coating, with a Shore hardness of 55-60HA. The wiping pressure is evenly distributed (0.3-0.5N/cm), ensuring 100% tight contact with the curved surface of the windshield, eliminating blind spots, and achieving a cleaning rate of ≥98%, effectively preventing watermarks and fogging. The graphite coating reduces the coefficient of friction to below 0.15, resulting in wiping noise ≤55dB(A), far exceeding the quietness of traditional framed wipers and reducing visual and auditory fatigue after prolonged use. The wiper blade exhibits strong weather resistance, showing no hardening or cracking after high and low temperature cycling tests from -40℃ to 80℃, with a service life of ≥1.5 million wipes, more than three times that of ordinary rubber wipers.

The wiper drive system uses a high-torque DC permanent magnet motor with a rated voltage of 24V, a rated power of 80W, and an output torque of ≥15N・m. It supports two speed settings (fast setting: 60 wipes/minute, slow setting: 30 wipes/minute) and an intermittent wiping function (interval time adjustable from 5-15 seconds) to adapt to different rainfall intensities and dust concentrations. The motor has built-in overheat and overload protection devices to prevent damage caused by short circuits or mechanical jamming. It can work continuously for ≥4 hours without failure. The linkage mechanism uses high-strength engineering plastic + zinc alloy shaft, treated with electrophoretic anti-corrosion, with a tensile strength of ≥40MPa. It does not loosen or jam under 25g peak vibration conditions, and the swing angle is precisely controlled at 90°±3° to ensure that the wiping range completely covers the effective field of vision of the windshield.

The wiper arm is made of Q235 high-strength carbon steel by stamping, and the surface is treated with electrostatic powder coating for corrosion protection. Its rust resistance meets the GB/T 10125 500-hour salt spray test standard, resisting mud and water immersion and outdoor UV aging. The arm body is designed with an arc-shaped fit, and the connection to the wiper blade uses a quick-release buckle, allowing a single person to replace the wiper blade in 10 seconds. The connection between the wiper motor and the linkage is equipped with an EPDM (ethylene propylene diene monomer) sealing cover with an IP65 protection rating, completely preventing dust and mud from entering the internal mechanics and circuitry, avoiding rust, jamming, and short circuits. The cover has a built-in buffer rubber pad to absorb operational vibrations and further reduce 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 front 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 bolts, allowing for complete disassembly and installation by a single person. After installation, it maintains a consistent appearance with the cab, has a low drag coefficient, and eliminates whistling wind noise during high-speed operation. An 8-10mm safety clearance is provided between the linkage mechanism and the edge of the windshield to prevent scratching the glass or sealing strips.

This front wiper assembly has passed multiple authoritative tests and certifications: GB/T 25684.8 Safety and Performance Requirements for Grader Wipers, IP65 Protection Rating Certification; 1.5 million wiper fatigue tests, with no blade deformation and no motor attenuation; wide temperature environment test 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 Standard for Automotive Electrical Equipment.
