The Ultimate Guide to Finding and Maintaining the Perfect New Holland L175 Oil Filter

2026-01-06

Owning a New Holland L175 skid steer loader means investing in a powerful and reliable workhorse.​​ To protect that investment, few things are as critical as selecting and maintaining the correct oil filter. The right oil filter is a fundamental component of your machine's preventive maintenance routine, directly impacting engine longevity, performance, and overall reliability. This comprehensive guide will provide you with all the knowledge needed to make an informed decision about your New Holland L175 oil filter, ensuring your equipment continues to operate at its best for years to come.

Understanding the Role of Your Oil Filter

The oil filter is the kidney of your New Holland L175's engine, performing the vital task of removing contaminants from the engine oil. These contaminants include microscopic metal particles from engine wear, soot, carbon deposits, and other abrasive substances that naturally accumulate as the engine operates. By trapping these harmful particles, the oil filter ensures that only clean oil circulates through the engine to lubricate, cool, and protect critical components like bearings, pistons, and cylinders.

A clogged or inefficient oil filter can lead to accelerated engine wear. When the filter becomes saturated with contaminants or its bypass valve opens due to high resistance, unfiltered oil can circulate through the engine. This abrasive-laden oil acts like sandpaper, gradually wearing down precision engine parts. Furthermore, a restricted filter can cause a drop in oil pressure, leading to inadequate lubrication and potential engine overheating. ​Regularly replacing your oil filter is one of the most cost-effective ways to prevent expensive engine repairs down the line.​

Identifying the Correct Oil Filter for Your New Holland L175

Using the correct filter is the first step in proper maintenance. The New Holland L175 typically uses specific part numbers that you should verify before purchase. Key original equipment manufacturer (OEM) part numbers include ​BG5X6731AA​ and ​878032602. An alternate reference number is ​LF16015J2. Using a filter that matches these specifications ensures a proper fit and correct thread pitch, preventing leaks and guaranteeing optimal filtration.

Many owners opt for filter kits that include all necessary filters for a full service. One highly recommended option is the ​ST-7043 Filter Kit, which is noted for being compatible with the New Holland L175 1,3. This kit often includes not just the engine oil filter, but also hydraulic, fuel, and air filters, making comprehensive maintenance more convenient. Another brand that receives positive user feedback is the LSSOCH Heavy Duty Oil Filter, which is also noted for its compatibility with the L175 model 4.

When selecting a filter, it's crucial to choose one designed for your specific machine rather than a generic alternative. The right filter will have the correct dimensions, sealing surface, and anti-drain back valve to maintain oil pressure upon startup. Always double-check your tractor's manual or consult with a knowledgeable supplier to confirm compatibility.

Step-by-Step Guide to Replacing Your Oil Filter

Replacing the oil filter on your New Holland L175 is a straightforward task that can be completed with some basic tools. Always prioritize safety by ensuring the machine is on a level surface, the engine is cool, and the parking brake is securely engaged.

  1. Drain the Engine Oil:​​ Before removing the old filter, place a drain pan underneath the engine oil drain plug. Use a wrench to remove the plug and allow the old oil to drain completely. While the oil is draining, you can prepare the new filter.
  2. Remove the Old Oil Filter:​​ Locate the oil filter, which is typically mounted on the engine block. Use an ​oil filter wrench​ to loosen it. Turn it counterclockwise. Be prepared for some residual oil to spill out as you remove the filter; keep the drain pan underneath to catch it.
  3. Prepare the New Oil Filter:​​ Before installing the new filter, take a moment to prep it. Apply a thin layer of new engine oil to the rubber ​gasket​ on the top of the filter. This lubrication is essential for creating a good seal and will make the next removal much easier.
  4. Install the New Oil Filter:​​ Screw the new filter onto the engine mount by hand. Once the gasket makes contact with the mounting surface, tighten it further. The correct tightness is key. ​Hand-tighten the filter first, then use a wrench to give it an additional three-quarters of a turn5,7. Avoid over-tightening, as this can damage the gasket and make the filter extremely difficult to remove next time.
  5. Refill with New Oil:​​ Once the new filter is securely in place and the drain plug has been reinstalled and tightened, refill the engine with the recommended type and quantity of new oil. Refer to your owner's manual for the exact specifications.
  6. Check for Leaks:​​ Start the engine and let it run for a few minutes. While it's running, inspect the area around the new oil filter and the drain plug for any signs of leakage. Turn off the engine, wait a moment, and then check the oil level with the dipstick, adding more oil if necessary to bring it to the proper level.

Recommended Maintenance Schedule and Best Practices

Adhering to a regular maintenance schedule is non-negotiable for equipment longevity. For the New Holland L175, the oil and oil filter should be changed at intervals specified in the operator's manual, which is typically every ​100 to 200 operating hours​ or at least once a year, whichever comes first. However, if you operate your machine in severe conditions—such as extreme dust, frequent cold starts, or heavy-load applications—more frequent changes are advisable.

When performing an oil change, it is highly recommended to use a ​complete filter kit. Kits like the ST-7043 or CFKIT Maintenance Filter Kit allow you to replace the oil, fuel, air, and hydraulic filters simultaneously 1,3,4. This holistic approach ensures that all fluid systems are protected from contamination, providing peace of mind and maximizing the interval between services. Keeping a log of your maintenance activities, including the date, hours, and parts used, will help you stay on track and maintain a valuable record for the machine's life.

Conclusion: Protect Your Investment with the Right Filter

The New Holland L175 is a durable machine built for tough work, and its maintenance should be treated with the same seriousness. Choosing the correct oil filter—whether an OEM part like ​BG5X6731AA​ or a quality aftermarket kit like the ​ST-7043—and installing it correctly is a simple yet profoundly effective way to safeguard your engine. By understanding the part numbers, following a careful replacement procedure, and adhering to a consistent maintenance schedule, you can ensure your skid steer loader remains a reliable asset on your job site for countless hours to come.
