Common Issues with Various Filters in Excavators

The fuel filter removes impurities such as oxidized iron and dust from the fuel, preventing blockages in the fuel system, reducing mechanical wear, and ensuring the stable operation of the excavator's engine.

Under normal circumstances, the replacement cycle for the excavator's engine fuel filter is to replace it after the first 250 hours of operation, and then replace it every 500 hours of operation thereafter. The specific replacement time should be flexibly determined based on the quality grade of the fuel. When the filter pressure gauge alarms or indicates abnormal pressure, it is necessary to check for any abnormal phenomena in the filter, and if found, it must be replaced.

When there is leakage or deformation on the surface of the filter element, it is necessary to check for any abnormal phenomena in the filter, and if found, it must be replaced.

Does a Higher Oil Filter Precision Mean Better?

For an engine or equipment, an appropriate filter precision should achieve a balance between filtration efficiency and dust holding capacity. Using a filter with excessively high filtration precision may shorten its service life due to its low dust holding capacity, thereby increasing the risk of the oil filter being blocked prematurely.

How Do Inferior Engine Oil and Fuel Filters Differ from Genuine Ones?

Genuine engine oil and fuel filters can effectively protect equipment and extend its service life, while inferior ones cannot provide adequate protection, fail to extend equipment life, and may even worsen equipment condition.

What Are the Benefits of Using High-Quality Engine Oil and Fuel Filters for Machines?

Using high-quality engine oil and fuel filters can effectively prolong the equipment's service life, reduce maintenance costs, and save money for users.

Is It Necessary to Use High-Quality Filters for Equipment That Has Exceeded the Warranty Period and Has Been Used for Many Years?

Old equipment engines are more prone to wear, leading to cylinder pulling. Therefore, old equipment requires high-quality filters to stabilize the increasing wear and maintain engine performance.

Otherwise, you will have to spend a large amount of money on repairs, or you will have to scrap your engine prematurely. By using genuine filters, you can ensure that your total cost of ownership (maintenance, repairs, overhaul, and depreciation) is minimized and extend the engine's service life.

Is It Enough for Filters to Be Cheap and Installable on the Engine?

Many domestic filter manufacturers only focus on replicating the geometric dimensions and appearance of OEM parts and neglect the engineering standards that filters should meet, or they don't even understand what engineering standards entail.

Filter design is aimed at protecting the engine system. If the filter performance does not meet technical requirements and loses its filtering effect, the engine's performance will significantly decrease, and its service life will be shortened.

For example, the life of a diesel engine is directly related to the 110-230 grams of dust it "eats" prematurely. Therefore, low-efficiency inferior filters will allow more impurities to enter the engine system, causing the engine to require major repairs prematurely.

If the filters being used have not caused any problems for the machine, is it necessary for users to spend more money on buying high-quality filters?

The impact of low-efficiency inferior filters on the engine may not be immediately apparent or may not be noticed at all. The engine seems to run normally, but harmful impurities may have already entered the engine system, causing corrosion, rust, wear, etc., to engine parts.

These damages are latent and will erupt when accumulated to a certain extent. Although there are no signs now, it does not mean that the problem does not exist.

Once a problem is discovered, it may be too late, so insisting on using high-quality guaranteed genuine filters can provide the engine with the maximum protection.
