Premium D1105 Kubota Oil Filter P551042 B7298 1C020-32430 1C010-32430 LF3795 3517857

‌Q: How do I change the D1105 Oil Filter?

‌Preparation and Safety‌

• ‌Hot the car first.‌ Start the engine and let it run a few minutes. This warms the oil for better drainage.
• ‌Park safely.‌ Put the car on level ground. Set the handbrake firmly. Use wheel chocks behind the front tires.
• ‌Gather your tools.‌ You'll need: new engine oil, a new oil filter (confirm it's the right model), an oil drain wrench, an oil filter wrench, a drain pan, a funnel, gloves, and clean rags.
• ‌Lift the car securely.‌ Jack up the vehicle. Always use jack stands for solid support. Never work under a car supported only by a jack.

‌Drain the Old Oil‌

• ‌Find the drain plug.‌ It's on the bottom of the oil pan.
• ‌Place the drain pan.‌ Position it directly under the plug.
• ‌Loosen the plug.‌ Use the wrench to turn it counterclockwise. Let all the oil drain out completely. Then tighten the plug again.
• ‌Check the gasket.‌ Look at the drain plug's sealing surface. If it's worn or damaged, replace it.

‌Remove the Old Filter‌

• ‌Locate the filter.‌ It's usually mounted on the engine block.
• ‌Loosen the filter.‌ Use the filter wrench to turn it counterclockwise. Remove it by hand.
• ‌Clean the area.‌ Wipe off any old seal residue and oil stains from the filter mount surface.

‌Install the New Filter‌

• ‌Lubricate the seal.‌ Put a thin coat of new oil on the rubber gasket of the new filter.
• ‌Hand-tighten the filter.‌ Screw it on by hand until the gasket touches the mount. Then give it an extra 3/4 turn with the wrench. (Don't over-tighten!)

‌Add New Oil‌

• ‌Insert the funnel.‌ Put it in the oil filler hole.
• ‌Pour in the oil.‌ Add the correct amount and type of new oil.
• ‌Replace the cap.‌ Screw the oil filler cap on tightly.

‌Final Checks‌

• ‌Start the engine.‌ Let it idle for a few minutes to circulate the new oil.
• ‌Turn it off.‌ Wait a few minutes for the oil to settle back in the pan.
• ‌Check the level.‌ Pull out the dipstick. The oil level should be between the MIN and MAX marks. Add more if needed.
• ‌Check for leaks.‌ Look under the car for any oil leaks around the drain plug and filter.
• ‌Dispose of waste properly.‌ Take the used oil and filter to a recycling center. Never throw them in the trash.

Q: What is the difference between a diesel oil filter and a gasoline oil filter?

The oil filter, as a key component of the engine lubrication system, has the core function of filtering metal debris, carbon deposits, and impurities in the engine oil to maintain oil cleanliness and engine lubrication efficiency. Although there are differences in the working environment between diesel engines and gasoline engines (such as higher compression ratios and higher working pressures), the design of oil filters mainly revolves around the flow characteristics, filtration accuracy, and pressure resistance requirements of the engine oil, rather than being directly determined by the fuel type.

Normally, the structure of the oil filter (such as housing material, filter paper type, bypass valve design) is adapted based on the overall power, speed, and lubrication system pressure of the engine, rather than simply distinguishing between diesel or gasoline power. Therefore, there is no essential difference in the basic principles and core functions of oil filters between diesel and gasoline vehicles. Both adopt a full flow filtration design to ensure the lubrication safety of internal moving parts of the engine.

However, some high-end or heavy-duty diesel engines may have higher requirements for oil filters, such as:

• Filtration efficiency: Diesel engines may produce more impurities after combustion, and some specialized filters may use higher precision filter materials (such as composite filter paper or synthetic materials) to capture smaller particles.

• Pressure and temperature resistance: Diesel engines operate at high temperatures and pressures, and the filter housing and seals may require enhanced heat resistance.
• Replacement cycle: The oil change cycle of diesel vehicles (especially commercial vehicles) is usually longer than that of gasoline vehicles, but filter replacement is often synchronized with oil to ensure filtering effectiveness.

In practical applications, the selection of oil filters is mainly based on the specifications of the vehicle manufacturer, rather than the type of fuel. Car owners should refer to the vehicle maintenance manual and use original or designated model filters that comply with API (American Petroleum Institute) standards to ensure compatibility and protection.

In summary:
• Consistent core functions: both are used to filter oil impurities and protect the engine.
• Weak design differences: The differences mainly stem from the overall power and operating conditions of the engine, rather than the diesel/gasoline itself.
Selection key: Follow the recommendations of the vehicle manufacturer, rather than simply distinguishing by fuel type.
