The WK1040 MAN Fuel Filter (Mixer) is a high‑efficiency filtration component designed specifically for the diesel fuel systems of SINOTRUK Howo trucks used in concrete mixer and heavy‑duty applications. As a trusted supplier of genuine Sinotruk howo parts, we offer this OEM‑grade fuel filter as a direct replacement for the original factory filter. The WK1040 MAN fuel filter delivers superior water separation and particulate removal, ensuring clean fuel injection, reduced injector wear, and consistent engine performance under the most severe operating conditions.
Engineered with a high‑capacity synthetic media and an advanced water‑repellent coating, the WK1040 MAN fuel filter provides exceptional filtration efficiency, capturing particles as small as 4 microns while effectively separating water from the fuel. Its robust steel housing with a corrosion‑resistant finish withstands high pressures and vibration, making it ideal for mixer trucks that operate in dusty, wet, and demanding environments.
OEM WK1040 MAN • Mixer truck application • 4‑micron efficiency • Water separator • Corrosion‑resistant housing
The WK1040 MAN is a premium fuel filter designed specifically for SINOTRUK Howo trucks equipped with MAN‑derived fuel systems, commonly used in concrete mixer and heavy‑duty transport applications. This filter plays a critical role in protecting the fuel injection system from contaminants and water that can cause injector sticking, corrosion, and premature pump failure.
The WK1040 MAN fuel filter features a high‑density synthetic fiber media that combines mechanical filtration with a hydrophobic water‑repellent treatment. This design effectively separates water droplets from the fuel, allowing them to settle at the bottom of the filter housing, while capturing abrasive particles down to 4 microns. The filter’s large surface area provides high contaminant holding capacity, extending service intervals.
A built‑in water drain valve allows easy removal of accumulated water during routine maintenance, preventing water from reaching the high‑pressure fuel pump and injectors. The robust steel canister is internally coated to prevent rust and is designed to withstand fuel system pressures up to 10 bar, ensuring reliable performance in all operating conditions.
Symptoms of a clogged or water‑saturated fuel filter include reduced engine power, rough idling, hard starting, and increased smoke emissions. Replacing the filter with the WK1040 MAN restores proper fuel flow, protects the injection system, and ensures optimal combustion efficiency. This OEM‑spec filter is the ideal choice for preventive maintenance and emergency replacements.
Whether you are performing scheduled servicing or addressing a fuel‑related issue, the WK1040 MAN Fuel Filter (Mixer) delivers the quality, reliability, and filtration performance that SINOTRUK Howo professionals demand.
The WK1040 MAN fuel filter is specifically designed for SINOTRUK Howo trucks equipped with MAN‑derived fuel injection systems, commonly found in mixer trucks, dump trucks, and heavy‑haul vehicles that operate in demanding conditions. It is a direct OE replacement and is fully compatible with all factory filter heads and fuel line connections.
This filter is essential for applications where fuel quality may vary, such as remote construction sites, mining operations, and areas with high humidity. In these environments, water and particulates in diesel fuel can cause severe injector damage and pump wear. The WK1040 MAN provides the water separation and filtration capacity needed to keep the fuel system clean and reliable.
When replacing the fuel filter, it is recommended to inspect the fuel lines, primer pump, and filter housing for any signs of contamination or damage. The WK1040 MAN is designed to work with standard diesel fuels and biodiesel blends up to B20, ensuring flexibility for fleet operators.
For fleets with multiple Howo mixer trucks, standardizing on the WK1040 MAN simplifies inventory management and ensures the correct filter is available for scheduled services. Always verify the filter thread and dimensions on your specific truck to confirm compatibility, though the WK1040 MAN is the standard filter for most Howo mixer and heavy‑duty applications with MAN fuel systems.
Replacing the WK1040 MAN fuel filter is a straightforward procedure that can be performed by most technicians using standard hand tools. Begin by relieving the fuel system pressure and placing a suitable container under the filter to catch any spilled fuel.
Remove the old filter by turning it counterclockwise with a filter wrench. Clean the mounting surface on the filter head, ensuring the old gasket is completely removed. Apply a thin film of clean diesel fuel to the new filter’s gasket to ensure a proper seal. Screw the new WK1040 MAN filter onto the head until the gasket contacts the sealing surface, then tighten an additional ¾ to 1 full turn (or to the manufacturer’s torque specification).
After installation, prime the fuel system using the primer pump until fuel flows from the vent screw, then close the vent. Start the engine and check for leaks around the filter. If the filter has a water drain, open it briefly to purge any air and ensure proper water separation function.
For maintenance, replace the fuel filter at every recommended service interval, typically every 10,000‑15,000 km for heavy‑duty mixer applications, or more frequently if operating in areas with poor fuel quality. Regularly drain accumulated water from the filter using the drain valve – this should be done weekly or whenever the water‑in‑fuel warning light illuminates. Keep a log of filter changes to track maintenance schedules.
The WK1040 MAN fuel filter is manufactured in an ISO 9001‑certified facility using advanced pleating and bonding technologies. The synthetic filter media is sourced from top-tier suppliers and is tested for efficiency, water separation capability, and resistance to fuel degradation. The steel housing is formed from high‑grade steel and coated with a durable anti‑corrosion finish.
Each filter undergoes comprehensive quality control checks, including media integrity testing, water separation performance verification (SAE J1488), burst pressure testing, and leak testing under vacuum and pressure. Random samples from each production batch are subjected to endurance testing on a fuel system test bench to validate filtration performance and structural durability over the filter’s service life.
We back the WK1040 MAN with a comprehensive 12‑month warranty against material and workmanship defects. Our commitment to quality ensures that every filter delivers the same level of protection and performance as the original equipment, giving you confidence in your fuel system’s reliability.
