As a trusted source of genuine Sinotruk howo parts, we offer this OEM-grade filter as a direct replacement for the original factory element. The LG9704190040/1 filter delivers superior contaminant removal, protecting vital chassis systems – including fuel, oil, or hydraulic circuits – from abrasive particles, moisture, and sludge. Manufactured with high-grade filtration media, precision-wound layers, and a durable metal or plastic housing, this filter ensures consistent flow rates, low pressure drop, and extended service intervals, keeping your HOWO truck running efficiently and reliably in the most demanding conditions.
The LG9704190040/1 filter is essential for maintaining clean fluids, preventing premature wear of pumps, injectors, and valves, and reducing the risk of costly component failures. Its exact OEM specifications guarantee a perfect fit and hassle-free replacement.
OEM direct replacement • High-efficiency filtration media • Low pressure drop • Extended service life • Easy spin-on / cartridge installation
The LG9704190040/1 is a premium filtration element designed for use in the fuel, oil, or hydraulic systems of SINOTRUK Howo A7 and T7H series trucks. This filter effectively removes contaminants such as dirt, rust, metal particles, and water, ensuring that the fluid circulating through your truck’s critical systems remains clean and free of abrasive substances. This OEM-grade filter replicates the original part’s dimensions, thread size, bypass valve setting, and filtration efficiency, guaranteeing a direct drop-in replacement that maintains factory performance.
Constructed with a high-density cellulose-synthetic blend media, the LG9704190040/1 offers excellent particle capture efficiency (up to 99.5% at rated micron size) while maintaining a low pressure drop to ensure adequate flow to pumps and injectors. The media is pleated to maximize surface area, increasing dirt-holding capacity and extending the filter’s service life. A robust steel or engineering-plastic housing with integral seals prevents bypass and leakage, ensuring that all fluid passes through the filtering medium.
The LG9704190040/1 filter also features a built-in bypass valve that opens in case of excessive pressure drop (e.g., cold start or clogged filter), ensuring that fluid continues to flow to vital components even under extreme conditions, though regular replacement is still recommended to maintain optimal protection. Its reliable construction and high-quality materials make it suitable for both on-highway and off-highway applications.
This filter is interchangeable with earlier LG9704190040 and is a popular choice for routine maintenance, scheduled overhauls, or emergency replacements. Its consistent performance and durability help extend the life of your HOWO’s fuel injection system, engine, or hydraulic components.
The LG9704190040/1 Filter is designed for use in SINOTRUK Howo A7 and T7H series trucks, including models ZZ4257, ZZ3257, and other variants with compatible fuel, engine oil, or hydraulic filtration systems. It serves as a direct replacement for the original filter and is also backward-compatible with the earlier LG9704190040 version.
This filter is widely used in fuel supply systems (primary or secondary fuel filters), lubrication circuits, and hydraulic steering systems. Its high-efficiency media makes it suitable for both common-rail and mechanical injection systems, as well as power steering and suspension hydraulics. The LG9704190040/1 is a preferred choice for fleets and owner-operators who demand reliable filtration to protect their truck’s critical components.
In demanding applications such as long-haul transport, construction, and mining, the filter is exposed to high levels of contamination and harsh operating conditions. The LG9704190040/1 is engineered to withstand these environments, maintaining its filtration efficiency and structural integrity even under severe vibration, pressure spikes, and temperature extremes.
When replacing a filter, always cross-reference the original part number and confirm the application (fuel, oil, or hydraulic) to ensure the correct media and bypass setting. The LG9704190040/1 covers the majority of Howo A7 and T7H fluid filtration needs, making it a versatile stocking item for workshops and fleets.
Replacing the LG9704190040/1 filter is a routine maintenance task that can be performed with standard hand tools. Begin by locating the filter housing – typically positioned near the engine, fuel tank, or hydraulic pump. Ensure the engine is cool and the system is depressurized before proceeding.
For spin-on types, use a filter wrench to remove the old filter by turning it counterclockwise. For cartridge types, remove the housing cover and extract the old element. Clean the mounting surface and inspect the O-ring or seal for any damage. Apply a thin film of clean fluid to the new seal.
Install the new LG9704190040/1 filter by hand-tightening it until the seal contacts the base, then give it an additional 1/2 to 3/4 turn as per the manufacturer’s recommendation (do not overtighten). For cartridge types, insert the new element, replace the cover, and tighten to the specified torque. Reconnect any hoses or lines if disconnected.
After installation, start the engine and check for leaks. Run the engine for a few minutes, then re-check the filter and surrounding area for any seepage. If the system uses a fuel filter, bleed the air according to the vehicle’s procedure.
For maintenance, always replace the filter at the intervals specified in your truck’s service schedule – typically every 500-1,000 hours of operation or annually, whichever comes first. In harsh environments with high dust or moisture, more frequent changes may be necessary. The LG9704190040/1 is designed to meet or exceed OEM service life requirements, but timely replacement is essential for optimal engine and component protection.
The LG9704190040/1 Filter is manufactured in an ISO 9001 and ISO 14001-certified facility using advanced automated assembly lines. The filter media is sourced from leading global suppliers and tested for burst strength, particle retention, and flow characteristics. Each filter is subjected to rigorous quality checks, including pressure integrity testing, media pleat uniformity inspection, and seal leak testing.
Random samples from each production batch undergo destructive testing to verify burst pressure (up to 15 bar), collapse resistance, and filter efficiency per ISO 4548 (for oil) and ISO 19438 (for fuel). The bypass valve is calibrated to open at the specified differential pressure, ensuring reliable protection in all conditions.
We back the LG9704190040/1 with a comprehensive warranty against material and workmanship defects. Our quality assurance ensures that every filter delivers the same performance, fit, and reliability as the original SINOTRUK Howo part, giving you confidence in your truck’s fluid cleanliness and component longevity.
