Fleetguard Diesel Oil/Lube Filter LF3000 — 1-Pack, Synthetic Full-Flow with Stacked-Disc Bypass

Fleetguard LF3000 is a heavy-duty diesel oil/lube filter that combines synthetic full-flow media with a stacked-disc bypass to protect engines and maintain oil circulation under extreme conditions.

The LF3000 is a one-pack replacement oil filter designed for diesel engines where robust contaminant removal and dependable bypass protection are required. Built to cross-reference common OEM part numbers including Cummins and New Holland, this Fleetguard filter fits applications that previously used LF670, LF777, LF691, or LF3333. Its combination of full-flow filtration and a stacked disc bypass ensures continued oil flow if the primary media becomes restricted, giving service technicians confidence during long duty cycles and high soot loads.

How does the LF3000 protect diesel engine oil systems?

The LF3000 uses synthetic media to capture fine particulates while allowing consistent oil flow through the full-flow element. If the filter becomes clogged or during cold starts, the stacked-disc bypass opens to preserve lubrication, reducing the risk of oil starvation to critical components.

• Synthetic filter media traps small contaminants and soot.
• Full-flow design filters oil on every circuit pass for continuous protection.
• Stacked-disc bypass provides an alternate oil route when restriction occurs.
• Durable construction for heavy-duty and high-vibration environments.

Which engines and part numbers is the LF3000 compatible with?

This filter is cross-referenced to multiple OEM numbers and fits many diesel applications that accept LF670, LF777, LF691, or LF3333 replacements. It’s commonly used where Cummins and New Holland equivalent parts are specified.

• Crosses to Cummins 3318853 and 3825970.
• Matches Donaldson FI P553000 and Biurrarena 143115 equivalents.
• Compatible with New Holland 9703112 in approved installations.
• Check vehicle or engine parts manual for fitment confirmation.

What are the installation and maintenance considerations for this filter?

Install the LF3000 following manufacturer torque and sealing guidelines to ensure proper sealing and function. Replace at recommended oil-change intervals or sooner if diagnostics indicate elevated restriction or contamination.

• Use correct torque values and replace gasket if applicable.
• Inspect oil condition at each service—change filter when oil is changed.
• Monitor system pressure and bypass activation as part of routine checks.
• Dispose of used filters according to local environmental regulations.

What distinguishes this Fleetguard filter from standard single-element filters?

The LF3000’s combined approach—synthetic full-flow media plus a stacked-disc bypass—delivers both high-efficiency contaminant capture and reliable oil flow backup. This dual design reduces the likelihood of lubricant starvation while maintaining filtration performance under heavy loads.

• Synthetic media offers higher particulate retention than basic cellulose elements.
• Stacked-disc bypass reacts progressively to restriction, protecting the engine during extreme conditions.
• Engineered for heavy-duty cycles and extended service intervals when recommended by OEM.
• Manufactured to Fleetguard quality standards for consistent fit and function.

Who is this for: The Fleetguard LF3000 is intended for fleet managers, service technicians, and diesel vehicle owners who operate heavy-duty engines in construction, agriculture, trucking, or industrial settings. It’s a good choice when OEM-equivalent performance, dependable bypass protection, and compatibility with Cummins or New Holland cross-references are required. Always verify fitment with your engine model and follow maintenance intervals recommended by the equipment manufacturer.
