Q: What is the difference between LF3345 and LF3805?

LF3345 and LF3805 are two commonly spin-on oil filter models for Cummins engines. They have differences in design, mainly reflected in their compatibility with engine models, physical dimensions, filtration performance, and application scenarios.

LF3345: This is a standard spin-on oil filter widely used in Cummins series medium-sized engines, such as ISF2.8, ISF3.8, and other models. It has good filtration efficiency and durability, and is a standard configuration for many commercial vehicles and construction machinery.
LF3805: As an alternative or upgraded model to LF3345, People has optimized in design, typically with a larger filtration area and higher filtration accuracy, providing better oil cleaning results. It is for Cummins engines that require higher filtration performance, such as certain new or high-power ISF series engines.

The main differences are summarized as follows:

• Engine adaptation: LF3345 is mainly suitable for Cummins ISF2.8, ISF3.8 and other engines; LF3805 is more commonly used for new Cummins engines that require higher filtration performance, and specific details need to be confirmed in the engine manual.
• Filtration performance: LF3805 usually has more advanced filter materials and structures, higher filtration efficiency, and can more effectively capture small impurities.
• Physical dimensions and interfaces: Although both are screw on filter cartridges, there may be differences in thread specifications, seal ring dimensions, or overall height, and they cannot be directly interchanged. Before installation, it is necessary to verify the designated model of the engine.

• Application scenario: LF3345 is a widely used universal model; LF3805 focuses more on high-end or heavy-duty applications that require higher reliability and longer oil change cycles.
• Important note: Although LF3805 may perform better than LF3345, they are not universal accessories. To ensure the normal operation and effective warranty of the engine, it is necessary to strictly replace the designated model of oil filter according to the specifications of the engine manufacturer.

Q: How can I tell if my Fleetguard filter is bad?

‌Identification signs of a bad oil filter‌
If your Fleetguard filter is an oil filter, you can check for failure with these signs:

• The oil pressure warning light turns on. A clogged filter reduces oil flow, lowering oil pressure and activating the dashboard warning.
• The engine makes abnormal noises. Knocking or friction sounds suggest insufficient lubrication due to filter failure, worsening internal wear.
• Engine oil quality declines. Normal oil looks light yellow or brown. Dark black, cloudy oil, or metal shavings mean the filter can’t purify oil effectively.
• Oil leaks appear. Check for stains at the filter’s bottom or installation site. Aging seals or housing damage (like sand holes) can cause leaks.
• Oil consumption accelerates abnormally. If no external leaks exist but oil levels drop fast, internal circulation issues or a damaged filter element may be the cause.

Q: What is the tool called to remove an oil filter?

The specialized tool for removing oil filters is commonly referred to as an oil filter wrench or oil filter spanner. Due to the varying shapes, sizes, and mounting methods of oil filters across different vehicle models, a range of specialized tools are available to meet diverse needs.

Common types of oil filter wrenches include:
• Cap-type (bowl-shaped) wrench: Resembles a socket, designed for removal by fitting over the groove or flange at the top of the filter. Suitable for most standard filters, often purchased in sets to cover various sizes.
• Three-jaw (planetary) wrench: Features internally adjustable jaws capable of gripping filters with varying diameters. Typically requires use with sockets or handles, offering broad adaptability but a relatively complex structure.

• Ring (adjustable) wrench: Features a serrated inner ring design that can be slipped over the top of the filter for secure fastening. Easy to operate without requiring precise size matching, ideal for quick disassembly and assembly.
• Pincer-type (clamping) wrench: Resembles a heavy-duty pliers or fish pliers, which rotate by clamping onto the filter housing. It is lightweight and portable but less suitable for large or hard-to-reach filters.
• Chain (or belt) wrench: Wraps around the filter body with a chain or belt, applying force through the principle of leverage, suitable for confined spaces or situations where other tools cannot be used.

In practical operations, it is recommended to select the appropriate tools based on the specific model of the vehicle's oil filter to ensure a safe and efficient removal process. Some tool kits (such as 1/2-inch drive socket sets) are also commonly chosen by professional mechanics to accommodate the needs of various vehicle models.
