What Are the Exact Specifications of the LF9009 Filter?
Understanding the physical dimensions and thread size is critical before purchasing an LF9009 filter. An incorrect fit can lead to oil leaks or engine damage.
Here are the key specifications:
Overall Height: 296mm to 302mm (approximately 11.88 inches)
Outer Diameter: 118mm (approximately 4.65 inches)
Thread Size: 2 1/4-12 UNS-2B
Gasket Inside Diameter: 101.85mm (4.01 inches)

Which Engines Use the LF9009 Filter?
The LF9009 filter is specifically engineered for Cummins engines. It is commonly found on the Cummins 6CT 8.3-liter engine .
This filter is compatible with both electronic common rail and mechanical pump engines. You will often find it specified for:
Dongfeng Tianlong trucks
Foton Auman CTX series
Various construction machinery with Cummins power
Why Is the LF9009 Filter Important for Engine Health?
The LF9009 filter plays a vital role in removing contaminants from engine oil. It traps dirt, oxidized oil, and metallic particles that accumulate during normal engine wear .
Clean oil ensures proper lubrication of moving parts. Without an effective filter like the LF9009 filter, these contaminants would cause accelerated wear on bearings and cylinder walls.
What Filtration Technology Does It Use?
Many versions of the LF9009 filter utilize StrataPore synthetic media. This technology combines cellulose and synthetic fibers to capture small dirt particles efficiently .
Some advanced versions also feature NanoNet media. This nanofiber technology offers higher efficiency and longer filter life compared to standard cellulose filters .
How to Choose Between Genuine Fleetguard and Aftermarket LF9009 Filters?
Choosing the right LF9009 filter depends on your budget and operating conditions.
Genuine Fleetguard: Guarantees OEM specifications and quality control. Recommended for engines under warranty or severe-duty applications.
Aftermarket (e.g., Donaldson, WIX): Often manufactured to similar standards. These can be more affordable and readily available.
Budget Options (e.g., Coralfly): Suitable for light-duty or older equipment. Verify certifications like RoHS if required .
Common Questions Answered Directly
Q1: How often should I change my LF9009 filter?
You should replace the LF9009 filter during every oil change. For diesel engines, this is typically every 15,000 kilometers or annually. Always consult your engine manufacturer's handbook for specific intervals .
Q2: Is the LF9009 filter the same as the LF3000?
The LF9009 filter is actually an upgrade or superseding part for the older LF3000. While dimensions may be similar, the LF9009 features improved filtration media .
Q3: Can I use the LF9009 filter on non-Cummins engines?
Yes, but only if the engine has the correct oil filter housing with 2 1/4-12 threads. Always check the cross-reference list above or compare the old filter physically before installation.
Q4: Where is the LF9009 filter manufactured?
Fleetguard filters are manufactured globally, with origins including the United States and France . Chinese joint ventures like Shanghai Fleetguard also produce this model .
Q5: What happens if I don't change my LF9009 filter regularly?
A clogged LF9009 filter will force the bypass valve to open. This allows unfiltered oil to circulate, leading to rapid engine wear and potential failure .
Frequently Asked Questions (FAQ)
What does the LF9009 filter fit?
It fits Cummins 6CT 8.3L engines, commonly found in Dongfeng天龙, Foton Auman CTX trucks, and various industrial generators.
Is the LF9009 a fuel or oil filter?
It is a lube oil filter, designed for engine oil. It is not suitable for fuel or hydraulic systems.
Does the LF9009 have an anti-drain back valve?
Standard specifications indicate no standpipe or anti-drain back valve is present in the standard LF9009 model .
What is the weight of the LF9009 filter?
The filter weighs approximately 1.65 kg to 1.74 kg .
Can I cross-reference LF9009 to a P553000?
Yes. The LF9009 filter is directly interchangeable with Donaldson P553000 .
Final Maintenance Tip
Always pre-fill your new LF9009 filter with clean oil before screwing it onto the engine. This prevents dry starts and immediate wear. Additionally, apply a thin layer of oil to the rubber gasket to ensure a proper seal and easy removal next service .
