The WG1642740010 Wiper Arm And Blade Assembly is a critical component in the wiper system of SINOTRUK Howo trucks. It mounts on the wiper motor spindle, transmits torque through the arm, and presses the rubber blade evenly against the windshield for clear driver visibility.
This WG1642740010 assembly is precision-manufactured to exact OEM dimensions. The splined pivot matches the motor spindle, the arm length and bend follow the factory sweep pattern, and the blade connector locks securely. Every unit is tested for correct fit and stable blade pressure.
Common signs that a wiper arm and blade assembly needs replacement include streaking, smearing or chattering on the glass, a blade that lifts at highway speed, a loose or stripped pivot spline, and a bent or corroded arm. Fitting a new assembly restores clear visibility.
Whether you are servicing worn wiper blades, replacing a damaged arm or carrying out preventive maintenance on a fleet of Howo trucks, the WG1642740010 Wiper Arm And Blade Assembly delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The WG1642740010 Wiper Arm And Blade Assembly is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it mounts onto the original wiper motor spindle and connects to the factory linkage without modification.
This assembly is essential in applications where driver visibility is critical, such as long-haul transport, construction, mining, logging and municipal service. In these duties, the wiper must maintain steady pressure and resist vibration, road salt, mud, ice and temperature extremes.
When replacing the wiper arm and blade assembly, it is recommended to inspect the wiper linkage, motor spindle splines, washer nozzle and windshield glass for wear or damage. The WG1642740010 is designed to work with the factory wiper system for correct fit and reliable operation.
For fleets with multiple HOWO trucks, standardising on the WG1642740010 Wiper Arm And Blade Assembly simplifies wiper system maintenance and ensures the correct assembly is available for scheduled service or emergency repairs.
Replacing the WG1642740010 Wiper Arm And Blade Assembly is a simple procedure that requires basic hand tools and care with the windshield glass. This work should be performed by a qualified technician. Begin by switching off the ignition and letting the wiper motor park in its rest position.
Lift the old arm away from the glass and release the blade connector. Remove the locking nut and washer from the motor spindle, then pull the old arm off the splines. Take care not to scratch the windshield or damage the spindle threads.
Clean the spindle splines and check them for wear. Fit the new assembly onto the spindle in the parked position, reinstall the washer and locking nut, and tighten to the OEM torque. Connect the blade and lower the arm gently onto the glass.
Operate the wipers and confirm a full, even sweep without hitting the pillar or overlapping the opposite arm. For ongoing maintenance, clean the blade edge with mild soap and replace the assembly at the first sign of streaking, chattering or lifting at speed.
The WG1642740010 Wiper Arm And Blade Assembly is manufactured in an ISO 9001-certified facility using high-strength stamped steel and a durable rubber blade compound. Raw materials are sourced from certified suppliers and undergo incoming inspection for dimensional accuracy, coating thickness and rubber hardness.
Each assembly is formed and assembled on precision lines and then tested for spline fit, spring tension, blade connector locking and sweep geometry. The arm is inspected for coating integrity, and every unit is subjected to a functional fit test before packing.
Random samples from each production batch undergo environmental testing, including salt spray, UV exposure, thermal cycling and vibration, to validate long-term reliability in heavy-duty truck applications. These tests ensure the assembly continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
