commercial truck engine filter replacement

13055724 Heavy Duty Spin-On Diesel Fuel Filter The 13055724 spin-on fuel filter is a premium aftermarket replacement component manufactured strictly to OEM standards for Weichai medium and heavy-duty diesel truck engines, also widely used on passenger coaches, engineering machinery and stationary diesel generator units. During long-distance haulage and continuous heavy-load operation, diesel fuel will inevitably contain rust sediment, metal wear debris, sludge, fine dust and tiny impurities generated during fuel storage and refueling. These contaminants entering the fuel system will scratch fuel pumps, block precision fuel injectors, cause rough idling, difficult cold starting, insufficient acceleration power and higher fuel consumption. This filter adopts multi-layer gradient composite pleated filter media to achieve high-efficiency particle filtration, delivering consistently clean diesel to the engine fuel injection system. It effectively protects core fuel system parts, stabilizes engine power output under harsh working conditions, reduces unexpected breakdown frequency and long-term maintenance costs. Produced under strict automotive quality control standards, it maintains stable filtration efficiency under high fuel pressure and wide temperature changes, serving as an essential reliable maintenance spare part for logistics fleets, vehicle repair shops and construction equipment teams.  Product Material Description: Filter Media: High-density multi-layer composite fiber filter paper with uniform pore size, outstanding filtration precision and large dirt holding capacity; Outer Shell: Thickened high-strength cold rolled steel housing with full electrophoretic anti-rust coating, resistant to diesel corrosion, physical impact and outdoor abrasion; Sealing Gasket: High-grade nitrile rubber (NBR), featuring excellent oil resistance, high & low temperature resistance and long anti-aging performance to realize full leak-proof sealing; Internal Reinforced Galvanized Metal Skeleton: Firmly supports the filter element to prevent deformation or collapse under sustained high working fuel pressure; Precision Standard Thread Interface: 1:1 consistent with original OEM thread size for perfect matching with the original mounting base.

1001120353A Heavy Duty Engine Oil Filter The 1001120353A oil filter is a precision aftermarket replacement filter specially developed to match Weichai series heavy-duty diesel engines, widely used on medium and heavy logistics trucks, dump trucks, passenger coaches and engineering vehicles. During long-distance haulage and continuous heavy-load operation, engine lubricating oil will inevitably mix with metal wear debris, carbon deposits, sludge, dust and tiny impurities generated inside engine operation. If these contaminants circulate in the lubrication system, they will cause severe abrasion to crankshafts, bearings, pistons and other precision core components, resulting in unstable oil pressure, engine noise, insufficient power, rising fuel consumption and shortened engine service life. Adopting advanced multi-layer gradient filtration technology, this 1001120353A filter efficiently traps fine solid pollutants to keep engine oil clean and smooth circulation of lubricant. It effectively reduces internal engine wear, lowers unexpected breakdown rates and daily maintenance costs. Produced strictly in line with automotive heavy-duty industrial standards, it maintains stable filtration performance under high oil pressure and high-temperature working environments, acting as a reliable safeguard for long-running fleets and engineering equipment working in complicated road and weather conditions.  Product Material Description: Filter Medium: High-density multi-layer composite fiber filter paper with compact pleated structure, stable filtration precision, large dirt holding capacity and excellent compatibility with all conventional diesel engine lubricating oil; Outer Housing: Thickened high-strength cold rolled steel shell with full electrophoretic anti-rust coating, resistant to engine oil corrosion, external impact and outdoor scratch damage; Sealing Gasket: High-performance nitrile rubber (NBR), featuring outstanding high temperature resistance, oil resistance and anti-aging properties, realizing complete tight sealing without oil leakage under long-term compression; Internal Reinforced Galvanized Metal Skeleton: Effectively supports the filter element to prevent deformation or collapse under long-time high lubrication pressure; Built-in Silicone Anti-Drain Back Valve: Prevents oil backflow after engine shutdown perfectly, avoiding dry startup wear on critical engine parts.
