Fleetguard LF9050 Oil Filter

Fleetguard LF9050 is a premium combined full – flow and bypass spin – on oil filter, specifically designed for Cummins engines with part number 4920071, and also suitable for Komatsu BF5209, Hitachi heavy – duty diesel engines. It is extensively applied to Dongfeng, Foton Auman heavy trucks, XCMG/SDLG loaders, excavators, and large – scale diesel generator sets. It adopts StrataPore composite filter media and Venturi Combo technology, attaining 98.7% filtration efficiency at 30 microns, effectively trapping metal chips, carbon deposits, and colloidal impurities in high – soot engine oil systems, reliably safeguarding crankshaft bearings, camshafts, fuel injectors, and turbochargers against premature wear.

Key specifications: 119.89mm outer diameter, 297.38mm height, M90×2 – 7H INT thread, and 101.60×118.87mm sealing ring, ensuring seamless fit with the original mounting position. It supports tool – free installation and maintains stable performance in the extreme temperature range of – 40°C to 125°C.

As an OEM – grade replacement filter, it offers long – lasting and reliable protection for the lubrication system under harsh operating conditions such as long – haul transportation, mining operations, and continuous power generation.

Advantages of  LF9050 Oil Filter

  • Dual Filtration Integration: Combines full – flow and bypass filtration. The Venturi tube design balances high efficiency and low flow resistance, increasing oil circulation efficiency by 25% compared with traditional filters.

  • StrataPore High – Efficiency Filtration: 30 – micron precision filtration captures 98.7% of impurities, reducing engine wear by 22% and extending oil change intervals by 20%.

  • Large Contaminant – Holding Capacity: The layered pore structure increases contaminant – storage space by 3-4 times compared with single – layer media, making it suitable for high – soot working conditions of construction machinery.

  • Extreme Condition Adaptability: Stable operation at – 40°C to 125°C; the reinforced steel shell can withstand 8bar oil pressure and 3G vibration load from rough terrain operations.

  • Cost – Effective OEM Replacement: Directly replaces Cummins 4920071, featuring OEM – level quality and a 20% lower price than original parts, which can significantly reduce the maintenance costs of fleets and engineering machinery teams.
