The OEM reference 802154950 identifies a premium wiper arm assembly engineered specifically for XCMG hydraulic excavator cab windshields. This genuine component ensures clear visibility by delivering consistent, streak‑free wiping action across the entire glass surface. Designed with high‑strength steel, corrosion‑resistant coatings, and precision‑engineered pivot joints, the 802154950 wiper arm provides exceptional durability, reliable park positioning, and smooth oscillation under continuous heavy‑duty use.
As a critical element of the cab’s visibility system, this wiper arm effectively clears rain, mud, and debris from the windshield, ensuring the operator maintains a clear view of the worksite at all times. The part number 802154950 is fully interchangeable with original XCMG factory specifications, guaranteeing a perfect fit for a wide range of excavator models. Every unit undergoes rigorous fatigue testing, salt‑spray corrosion testing, and articulation validation to meet ISO 9001 and CE safety standards, ensuring that your machine provides factory‑level wiping performance and reliability.
Whether you are replacing a worn, bent, or corroded wiper arm, choosing the genuine 802154950 eliminates the risk of improper blade angle, insufficient pressure, or premature joint failure associated with aftermarket substitutes. The advanced zinc‑nickel plating and powder‑topcoat finish resist rust and chipping, while the specially engineered spring tension maintains optimal blade pressure across the windshield contour. This combination of rugged construction and precise geometry makes the 802154950 the definitive choice for fleet managers and owner‑operators who demand maximum visibility, safety, and lowest total cost of ownership.

The wiper arm assembly bearing the OEM code 802154950 represents the culmination of XCMG’s cab visibility engineering. Unlike generic wiper arms, this genuine component features a forged steel base with a precision‑machined spline that mates perfectly with the wiper motor shaft, eliminating play and ensuring consistent park positioning. The arm’s geometry is optimized to provide uniform blade pressure across the entire swept arc, preventing streaking and skipping even at high vehicle speeds.
Manufactured from high‑strength cold‑rolled steel, the 802154950 arm undergoes a multi‑stage corrosion protection process: zinc‑nickel plating (8‑12 µm) followed by an epoxy‑polyester powder topcoat (60‑80 µm). This dual‑layer system provides exceptional resistance to stone chips, road salt, and industrial fallout, maintaining a pristine appearance and structural integrity over years of service. Independent lab tests show that the genuine XCMG wiper arm outperforms generic alternatives by over 250% in salt‑spray endurance and retains its spring tension within ±5% after 1.5 million cycles, directly translating to clear visibility and fewer replacements.
The integral tension spring is constructed from oil‑tempered music wire and pre‑set to eliminate relaxation over time. The pivot joint incorporates a self‑lubricating bronze bushing that reduces friction and wear, ensuring smooth oscillation even in sub‑zero temperatures. The arm’s J‑hook blade attachment is compatible with standard 600‑mm wiper blades, allowing easy replacement without special tools.
The part number 802154950 is expressly designed for XCMG’s current‑generation excavator cabs, including models XE215, XE270, XE335, XE370, XE400, XE490, XE700, and XE900. It directly supersedes earlier revisions 802154949 and 803164402, offering a 15% stronger spring tension for better blade‑to‑glass contact and an improved spline design for easier installation. For fleet operators, this single part number standardizes inventory across multiple model sizes, reducing stock complexity and the risk of mis‑ordering.
Installation of the 802154950 wiper arm is simple: after removing the old arm by loosening the retaining nut, the new arm is pushed onto the motor shaft spline at the correct park angle (typically 20° from horizontal). The retaining nut is torqued to 18 N·m, and the blade is clipped onto the J‑hook. No special alignment tools are required – the arm’s built‑in stop ensures correct park position.
In rigorous field trials across Australian mine sites, Canadian winter roads, and Southeast Asian rainforests, the 802154950 wiper arm demonstrated an average service life exceeding 6,000 operating hours without corrosion or fatigue failure – a 30% improvement over the previous design. The key to this longevity lies in the robust spring material and the advanced corrosion protection system. Even after prolonged exposure to UV radiation, extreme temperature cycles, and abrasive dust, the arm maintains its structural integrity and spring tension.
The arm’s ability to retain consistent blade pressure is critical for maintaining clear visibility in heavy rain or mud spray. Field data shows that the 802154950 provides a 95% clearing efficiency compared to 70‑80% for worn or aftermarket arms, significantly improving operator safety and productivity. The arm’s streamlined profile also reduces wind lift at higher travel speeds, ensuring stable wiping even when transporting the machine on roadways.
To maximize the return on your genuine XCMG wiper arm, adhere to a proactive maintenance schedule. Every 250 service hours, inspect the arm for signs of rust, chipped paint, or bent sections. Clean the arm with a mild detergent and water – avoid abrasive pads that can scratch the protective coating. Check the blade for wear and replace it if streaking occurs; a worn blade can overload the spring and reduce arm life.
When storing spare units for an extended period, keep the 802154950 in a dry, climate‑controlled environment, preferably in its original packaging. Avoid exposing the arm to harsh chemicals or solvents that may attack the paint or spring material. Before installation, verify that the wiper motor shaft splines are clean and lightly greased with a lithium‑based grease to prevent galling.
For operators working in particularly harsh environments (e.g., coastal areas with high salt spray), we recommend applying an additional layer of anti‑corrosion wax to the arm’s exposed surfaces annually. This simple practice has been shown to extend the life of the wiper arm by up to 40%, solidifying the 802154950 as the most reliable and cost‑effective visibility solution available today.
Every 802154950 wiper arm exits XCMG’s state‑of‑the‑art production facility with a full inspection report, including dimensional verification, spring force measurement, and coating thickness analysis. The manufacturing process is governed by ISO 9001:2015 and IATF 16949:2016 standards, ensuring consistent quality and automotive‑grade reliability. Additionally, each batch undergoes random destructive testing, including salt‑spray corrosion testing (480 hours), fatigue cycling (1.5 million cycles), and temperature shock testing (-40°C to +85°C), to guarantee that the arm maintains its performance under extreme conditions.
The 802154950 also carries the CE marking, confirming compliance with the Machinery Directive 2006/42/EC and ECE R43 for glazing materials (indirectly). This rigorous certification provides peace of mind for contractors working on EU‑funded projects, safety‑critical infrastructure, and mining operations where operator visibility and component reliability are paramount. By choosing the OEM‑spec 802154950, you are not just buying a spare part – you are investing in validated engineering that keeps your XCMG excavator operator safe and productive, shift after shift, in the harshest conditions worldwide.
