Wiper Mechanism and Support WG1642740009

Product Function​

The WG1642740009 wiper mechanism and support is what keeps heavy-duty truck drivers seeing clearly-right at the center of the cab's windshield cleaning setup. It's the part that gets the wiper blade moving steadily back and forth, wiping off rain, dust, and whatever grime builds up on the glass. No more squinting through messy windshields, even when the weather's brutal: heavy rains, sand blowing everywhere, or temperatures dropping way low. It's built tough with strong swing power and smooth movement, so it's perfect for those long-haul trucks, construction vehicles, and mining trucks that can't afford visibility issues when they're out working.​

Compatibility Details​

Applicable Vehicles: SINOTRUK HOWO's A7, T7H, and TH7 lines-covers heavy-duty trucks, tractors, and dump trucks​

Compatible Cab Models: Original HOWO cabs, both high-roof and standard-roof versions​

OE/OEM Number: WG1642740009-this is a direct swap for the original part, so it fits just like the factory-installed one​

Matching Tip: It uses standard mounting holes and transmission setup, so you can pop it right on without extra modifications. If you're not sure it fits, we can also match it precisely using your vehicle's VIN code-takes the guesswork out of it.

We don't cut corners on materials-we use high-strength plastic and zinc-plated steel that's been tested and certified in batches. The way we make these is pretty thorough too: precision stamping, gear cutting, putting the motor together, testing how much torque it has, and spraying it with anti-corrosion coating. All of this is done on automated production lines that can make 120,000 sets a year. So whether you need just a few or a whole bunch, we can keep up with your order.​

We've got three quality options to fit different budgets and needs:​

Genuine Parts: Made exactly to SINOTRUK's original technical specs-if you're maintaining a factory-original truck, this is the one to go for​

OEM Grade: Gives you good performance without the premium price tag-great value if you want reliability on a budget​

High-Quality Aftermarket: Solid for everyday use-gets the job done without any fuss​

Our factory is ISO9001 certified, so you know the quality is consistent. Every single wiper mechanism goes through a full inspection before it leaves the factory-we check if the swing angle is right, how smoothly the gears run, how strong the motor torque is, and if it starts up okay in cold weather. Each set also has a unique serial number, so if you ever need to track it back to when it was made, we can do that easily.​

How long will it last under normal use?​

Genuine Parts: 120,000km or 3 years-whichever comes first​

OEM Grade: 100,000km or 2.5 years​

High-Quality Aftermarket: 80,000km or 2 years​

What's better about this one compared to regular wiper mechanisms? For starters, it has 25% more swing torque-so even if the blade is covered in snow, it still moves easily. It's 30% quieter too-we tweaked the gear design to cut down on noise. And it handles cold way better: 40% more low-temperature resistance, so it fires up no problem at -40℃. All in all, it breaks down 30% less often than your average wiper mechanism.

Procurement Terms​

We keep over 800 sets in stock at all times, so you can get it right away-no waiting weeks for production. You can order just 1 set (we even send samples if you want to test it first), and if you order 150 sets or more, you'll get our wholesale price. Regular orders ship within 48 hours of you paying, and if you're ordering a big batch (500 sets or more), it'll take 5-7 working days to get ready.​

Packaging & Labeling​

You can choose how we package it: neutral cartons, your own brand packaging, or heavy-duty shockproof cartons for exports. Each product is wrapped in bubble wrap to keep it from getting scratched, and the bracket is held in place with a cardboard insert so it doesn't move around during shipping. The label on each unit has a barcode with the serial number, OE number, production date, and which quality grade it is-easy to keep track of.​

After-sales & Customization​

Warranty: Genuine parts have a 12-month or 120,000km warranty, OEM Grade has 10 months or 100,000km, and High-Quality Aftermarket has 6 months or 80,000km. If something goes wrong that's not your fault-like the motor burning out, gears getting stuck, or the bracket bending-we'll send you a new one for free.​

Technical Support: We're here to help if you need it. We can check if it's compatible with your vehicle, tell you the right torque for installation, give you tips on keeping the motor in good shape, and even help diagnose problems remotely if something isn't working.​

OEM/ODM Service: If you need something custom-like a different swing angle, bracket size, or more powerful motor-just send us your drawings or a sample. We can do small-batch custom orders starting at 50 sets, and it takes 10-15 working days to make them.

Practical Applications​

This wiper mechanism is a popular choice for HOWO heavy trucks-you'll find it all over the place: Southeast Asia, the Middle East, Central Asia, Russia, and Africa. It's used on long-haul logistics tractors that crisscross continents, mining dump trucks that tackle rough terrain, and engineering transport vehicles that work on construction sites. We've put over 100,000 sets on trucks in China alone, and we ship more than 25,000 sets to other countries every year.​

FAQ​

1.Can this wiper mechanism handle heavy snow and super cold temperatures?​

Yep, it's built for that. It has extra torque and a motor that doesn't mind the cold-even at -40℃, it'll start right up and work smoothly, even if the wiper blade is covered in snow.​

2.Is the support bracket strong enough for bumpy mining roads?​

Absolutely. The bracket is made of thick, stamped steel with reinforced welding-so all the bouncing and shaking on mining roads won't bend or break it.​

3.Does the assembly come with wiper blades and nuts?​

It's a complete mechanism and bracket set, and it includes the nuts you need for installation. But wiper blades aren't included-you can just use the ones that came with your truck, since they're compatible.​

4.How do I adjust how far the wiper swings?​

It's easy-just follow the installation guide we include. You can tweak the position where the transmission arm connects to the wiper shaft, and that'll change the swing angle.​

5.What usually goes wrong with wiper mechanisms, and how do I take care of this one?​

The most common issues are the motor burning out or gears getting stuck. To keep it running well, just clean out any dust from the gearbox every now and then and add a little lubricating oil-that'll make it last a lot longer.
