Fleetguard LF17559 Oil Filter

LF17559 is a heavy-duty spin-on oil filter by Fleetguard, exclusively designed for Cummins ISG 11.8L/12.9L and ISX 15L heavy-duty diesel engines and widely applied in Foton Auman GTL/ETX 430-550HP heavy trucks, Daimler commercial vehicles, long-haul logistics tractors, and large construction machinery. It adopts Fleetguard’s advanced StrataPore™ high-efficiency composite filter media, achieving 99% filtration efficiency at 20 microns to capture ultra-fine metal particles, carbon residues, and oil contaminants generated by high-power engines, effectively protecting crankshafts, camshafts, and turbochargers from premature wear.

Key specifications: 120mm outer diameter, 399mm height, and 1-1/2″-12UNF-2B thread specification with a 112mm outer seal diameter, perfectly matching original mounting positions. It supports tool-assisted quick installation and maintains stable performance in -40°C to 135°C extreme temperature ranges.

As an OEM-grade replacement for Cummins 3694654, it provides reliable lubrication system protection for high-load long-haul operations and heavy construction tasks, supporting 80,000km+ extended service intervals and reducing maintenance frequency for mixed fleet operations.

Advantages of  LF17559 Oil Filter

  • Dual-Engine Compatibility: Exclusively fits both Cummins ISG and ISX engines, solving the problem of filter mismatch in mixed fleet operations with both engine types, reducing inventory costs by 40%+.

  • StrataPore™ Composite Filtration: 20-micron precision captures 99% of contaminants, extending engine overhaul cycle by 25% and reducing long-term maintenance costs for heavy trucks and construction machinery.

  • Ultra-Long Service Life: 2.5X higher dirt-holding capacity than standard filters, supporting 80,000km+ service intervals ideal for cross-regional logistics and remote construction sites with limited maintenance resources.

  • Extreme Temperature & Pressure Resistance: Stable operation from -40°C to 135°C adapts to alpine regions and desert high-temperature environments; reinforced steel housing withstands 10bar oil pressure, eliminating deformation risks.

  • Cost-Effective Heavy-Duty Solution: Directly replaces 3694654 OEM parts, offering equivalent performance to original filters at 20% lower cost, while its extended service life further reduces total ownership costs for fleet operators.
