The primary differences between Komatsu original (OEM) filters and aftermarket filters lie in their quality, performance, and cost.Quality and Materials: OEM filters are made by Komatsu or approved manufacturers, ensuring they meet the company's strict design and quality standards. They are built to last and offer optimal filtration capabilities, protecting sensitive machinery parts like engines and hydraulic systems.

When it comes to Japanese imported machines, the Komatsu excavator stands out for its exceptional performance and durability, winning the hearts of machine enthusiasts in the Chinese market. However, regardless of the series, after thousands of hours of operation in various construction environments, Komatsu excavators encounter the challenge of adjusting the hydraulic pump.

Injector troubleshooting methods1. Few or no oil injected by the injector.2. Injector injection pressure is too low.3. Injector injection pressure is too high4. Leakage of fuel injector injectors5. Poor atomization of fuel injector injection6, Injector injection into the line7, Injector needle valve surface burned or blue-black color. Note: (diesel engine overheating) check the cooling system, and pay attention to the replacement of coupling parts.

On January 6, 2024, Jining Huida Construction Machinery Co., Ltd. held a grand 2023 annual summary and 2024 kick-off meeting at Mehood Hotel in Jining City.All colleagues of Huida Machinery gathered together to summarize and reflect on 2023, which is full of tension, fulfillment and growth. Mr.

When operating excavators, one of the most common issues faced is abnormal increase in diesel consumption or burning oil. This not only raises equipment operating costs but also leads to equipment wear and failure. To address this issue, it is crucial to identify the root causes of increased fuel consumption or burning oil.Excessive Wear of Components: The wear of the piston, piston ring, and cylinder liner can cause oil to escape into the combustion chamber, leading to a sharp increase in oil consumption.

Recently, Jining Huida Construction Machinery Co., Ltd. was honored to participate in CTT and XPO (Moscow International Construction Equipment and Technology Exhibition and Novokuznetsk Mining and Coal Exhibition). As an enterprise mainly engaged in machinery accessories, this exhibition showed the world the excellent quality and innovative strength of Made in China.Affected by the situation, many European and American brands have withdrawn from the Russian market one after another, which provides a good opportunity for Chinese manufacturers.

Bauma Russia 2023 came to a successful conclusion. With the joint efforts of all Huida staff, we have reached long-term cooperation with several customers, which is the best proof of our staff's hard work and dedication.Building long-lasting relationships with customers is crucial for the growth and sustainability of our business.
