Fleetguard LF9009 Oil Filter — Cross-Reference to Cummins 3401544
Fleetguard LF9009 oil filter is the Fleetguard number for Cummins 3401544 — a spin-on, combined full-flow and bypass lube element used on select Cummins engine builds. Whether it is the right filter for your engine depends on the engine serial or build record and the installed position, not on the model designation alone.

What LF9009 Is — and what to confirm
LF9009 and Cummins 3401544 are the same combined full-flow and bypass lube filter. Fitment follows the engine build; the ISX is commonly mis-listed. Newer X-platform builds supersede to LF14009NN. Confirm the engine serial and the number off the removed filter before ordering.
LF9009 is a combined dual-flow element: one spin-on canister carries both full-flow and bypass filtration. It supersedes the earlier Fleetguard LF3000. Fleetguard is a filter brand, not ours — LF9009 is a reference point, not a fitment statement. Manufacturer-published specifications include a 2.25-12 UNF thread, roughly 300 mm overall height, about 105 L/min rated flow, StrataPore media, and 30 micron (c) at 98.7% efficiency.

A cross-reference is a candidate to review, not proof of fitment. Two numbers can share a reference and still differ in media, seals, or valve.
Applications & ordering
Which engines use LF9009?
Cummins ISC, ISL/QSL, ISM, M11, N14, NTA855, and 6CT
LF9009 appears on select Cummins builds. The list is build-dependent: the same model designation can carry different elements across production years. Equipment type helps narrow the search; the engine build and installed filter position determine the match.
The ISX is commonly listed but often unconfirmed. Check the engine serial before trusting a listing.
How to confirm LF9009 before you order
Where two records disagree, send both — the difference usually points to a supersession, a build variation, or an element fitted to the wrong specification. Numbers can be checked by engine serial on Quickserve.

Request a QuoteFrequently Asked Questions
Is LF9009 the same as Cummins 3401544?
Yes. LF9009 is the Fleetguard number for Cummins 3401544, a combined full-flow and bypass lube filter. Confirm the build and position before ordering.
What engines does the LF9009 oil filter fit?
It appears on select Cummins builds including ISC, ISL/QSL, ISM, M11, N14, NTA855, and 6CT. Fitment is build-dependent, so confirm against the engine serial rather than the model name.
Does LF9009 fit a Cummins ISX?
Not reliably. Some retail listings include the ISX, but spec-oriented sources do not. Confirm against the engine serial; some newer X-platform builds move to LF14009NN.
What is the Baldwin equivalent of LF9009?
Baldwin lists BD7309 as the interchange for LF9009. Treat it as a candidate to review, not a confirmation of fitment.
What is a combined full-flow and bypass oil filter?
One element that does both jobs: the full-flow section filters the whole stream, and the bypass section polishes a metered portion. It is not interchangeable with a full-flow-only element where the build specifies otherwise.
Confirm the number. Then confirm the build.
LF9009 is a reference that gets you to a candidate filter, not a guarantee of fitment. Send the engine serial, the complete number off the old filter, and the installed position.
