Product Introduction

• Structure: A robust, single-piece arm made of heavy-duty steel with a durable black anti-corrosion coating. It features a spring-loaded design to maintain constant pressure against the windshield, and a quick-connect fitting for attaching the wiper blade.

• Performance: Transfers the rotational force from the wiper motor to the blade, ensuring smooth, consistent movement across the windshield. The spring mechanism keeps the blade firmly pressed against the glass, providing effective wiping even at highway speeds or in heavy rain.

Core Function

1. Force Transfer: Transmits power from the wiper motor to move the blade across the windshield.

2. Pressure Maintenance: The integrated spring ensures the blade stays in firm contact with the glass for optimal wiping performance.

3. Durability: The heavy-duty steel construction and corrosion-resistant coating withstand vibration, UV exposure, and harsh weather.

Wiper Arm WG1642740010 for Sinotruk HOWO Heavy-Duty Trucks – Factory Direct Supply

When your Sinotruk HOWO truck faces harsh weather on long-haul routes, a reliable wiper arm isn’t just a convenience — it’s a safety essential. The Wiper Arm WG1642740010 is engineered specifically for Sinotruk HOWO heavy-duty trucks, delivering consistent windshield-clearing performance that keeps drivers safe and fleets moving. At Mettlead, we supply this genuine-spec wiper arm directly from our factory in China, which means you get OEM-equivalent quality without the inflated markup. Whether you’re a fleet manager restocking maintenance parts or a procurement professional sourcing reliable components, this wiper arm offers the durability and precision fit your HOWO trucks demand.

Why Choose the Wiper Arm WG1642740010 for Your Sinotruk HOWO Fleet

Not all aftermarket wiper arms are created equal. Here’s what sets the WG1642740010 apart and why procurement managers across Africa, the Middle East, Southeast Asia, and South America trust it for their fleets:

Precise OEM Fitment

The Wiper Arm WG1642740010 is designed as a direct replacement for Sinotruk HOWO cab assemblies. It bolts on seamlessly without modification, saving your workshop valuable installation time. The arm’s geometry matches the original windshield curvature, ensuring full wiper blade contact and streak-free visibility in rain, dust storms, or mud splashes.

Heavy-Duty Corrosion Resistance

Built from high-strength steel alloy with a multi-layer anti-corrosion coating, this wiper arm resists rust even in humid tropical climates and salt-laden coastal environments. Consequently, it maintains its spring tension and structural integrity far longer than generic alternatives.

Optimized Spring Tension

The internal spring mechanism delivers calibrated pressure against the windshield. This ensures the wiper blade maintains consistent contact at all vehicle speeds — from low-speed urban driving to high-speed highway operation. As a result, drivers experience fewer missed spots and reduced wiper chatter noise.

Cost-Effective Fleet Maintenance

Because Mettlead supplies directly from our manufacturing base in China, you eliminate middlemen and unnecessary cost layers. Furthermore, our strict quality control process means fewer premature failures, reducing your overall replacement frequency and total cost of ownership.

Technical Specifications – Wiper Arm WG1642740010

Application – Compatible Vehicle Models and Scenarios

The Wiper Arm WG1642740010 is specifically designed for the following Sinotruk HOWO truck models and cab configurations:

• Sinotruk HOWO A7 Tractor Trucks
• Sinotruk HOWO 6×4 Dump Trucks
• Sinotruk HOWO 8×4 Cargo Trucks
• Sinotruk HOWO Concrete Mixer Trucks
• Sinotruk HOWO T-Series (T5G, T7H) Cab Variants

In real-world operation, these trucks often traverse unpaved roads in mining regions, navigate monsoon-season highways in Southeast Asia, or endure sandstorms in Middle Eastern logistics corridors. In each scenario, the wiper arm must deliver unfailing performance. The WG1642740010 is tested to handle these demanding conditions, ensuring drivers maintain clear forward visibility regardless of the environment. Additionally, for fleets operating mixed Sinotruk models, you can explore our full range of Sinotruk HOWO truck parts and truck cab components to consolidate your sourcing.

Customer Case Study – Wiper Arm WG1642740010 Bulk Order for East African Fleet

In early 2024, a fleet management company based in Kenya reached out to Mettlead. They operated over 120 Sinotruk HOWO dump trucks in a mining logistics corridor and were experiencing frequent wiper arm failures due to dust accumulation and corrosive mineral residue on their windshields. Their previous supplier’s generic wiper arms lost spring tension within three months, leading to poor visibility and safety concerns during the rainy season.

After evaluating samples of our Wiper Arm WG1642740010, their procurement manager confirmed the fitment was exact and the coating quality was visibly superior. They placed an initial order of 300 units with custom packaging bearing their company branding. Delivery was completed within 18 days via sea freight to Mombasa port.

Six months later, their maintenance reports showed zero premature wiper arm failures across the entire fleet. As a result, they expanded their sourcing from Mettlead to include additional Sinotruk HOWO cab parts, wiper motors, and mirror assemblies. This case illustrates how the right Wiper Arm WG1642740010 Sinotruk HOWO part, sourced from a reliable manufacturer, can reduce maintenance costs and improve fleet safety at scale.

Frequently Asked Questions – Wiper Arm WG1642740010 Sinotruk HOWO

Is the Wiper Arm WG1642740010 an exact OEM replacement?

Yes. The Wiper Arm WG1642740010 is manufactured to match the original Sinotruk HOWO specifications, including mounting dimensions, spline count, and spring tension. It installs directly without any modification to your truck’s wiper motor or linkage system.

What type of wiper blade connection does the WG1642740010 use?

This wiper arm uses the standard hook-type or spline-type connection (depending on cab variant) that is compatible with OEM and aftermarket wiper blades designed for Sinotruk HOWO trucks. It’s important to verify your specific cab model when ordering to ensure the correct arm variant.

How long does the anti-corrosion coating last on the Wiper Arm WG1642740010?

The dual-layer coating — electrophoretic base plus powder topcoat — is engineered to resist corrosion for the full service life of the arm under normal operating conditions. In extreme environments (coastal, high-humidity, or chemical-exposure scenarios), the coating still significantly outperforms single-layer painted alternatives, typically lasting 2–3 years without visible degradation.

Can I order just one piece of the Wiper Arm WG1642740010 for testing?

Absolutely. We encourage procurement managers to request samples before committing to bulk orders. This allows you to verify fitment, finish quality, and spring tension on your own fleet vehicles. Once satisfied, you can place volume orders with confidence.

Does the Wiper Arm WG1642740010 come with installation hardware?

The wiper arm ships with the mounting nut and any necessary washers as per the OEM configuration. No additional hardware is required for installation. A standard socket wrench is the only tool needed for replacement.

What’s the difference between the WG1642740010 and other HOWO wiper arm part numbers?

Sinotruk HOWO trucks use different wiper arm part numbers depending on the cab generation and windshield curvature. The WG1642740010 is specifically engineered for the designated cab variant. If you’re unsure which part number suits your truck, our technical team can help you cross-reference by VIN or cab model.
