What brand is the diesel filter element for Komatsu 70-8mo?
3 Answers
The diesel filter element for Komatsu 70-8mo is the original Komatsu brand, with filter paper imported from Japan and produced by domestic OEM manufacturers. Introduction to Komatsu Group: Komatsu Ltd. (Komatsu Group) is one of the world's largest manufacturers of construction and mining equipment. Established in 1921 with a history of over 90 years, the company is headquartered in Tokyo, Japan. Its main products include construction machinery such as excavators, bulldozers, loaders, and dump trucks; industrial machinery like large presses and cutting machines; logistics equipment such as forklifts; underground engineering machinery including TBMs and shield machines; as well as power generation equipment. Introduction to diesel filter elements: The diesel filter element is one of the crucial components ensuring the quality of diesel entering the engine. High-quality diesel filters can effectively block microscopic dust and moisture carried in diesel fuel, significantly extending the service life of fuel injection pumps, diesel nozzles, and other filtration components.
I remember the diesel filter brands for the Komatsu PC70-8mo excavator. The original equipment manufacturer (OEM) commonly uses Donaldson or Komatsu's own brand, with models like LF3349 being quite common. In the aftermarket, there are compatible options like Baldwin BF9842, which are more affordable but require ensuring the filtration accuracy meets standards. Why is the brand important? Low-quality filters don't clean effectively, allowing impurities to enter the fuel pump, accelerating wear and even causing shutdowns. I've seen many incidents caused by saving money with off-brand products. The recommended replacement interval is every 500 hours or every six months, but in dusty construction environments, it should be shortened to 300 hours. When replacing, clean the installation port and use a new sealing ring to avoid oil leaks. Store the filters in a dry place to prevent moisture from affecting performance. In short, matching Komatsu equipment with Donaldson brands is more reliable, ensuring proper maintenance to extend machine life and reduce repair costs.
When operating the Komatsu 70-8mo equipment, I have used the original Donaldson brand for diesel filters, and the after-sales service offers a more economical option with Baldwin. Self-maintenance saves costs, but avoid purchasing low-quality products as poor filtration can clog injectors, increase fuel consumption, and lead to frequent malfunctions. I’ve tested extending replacement intervals to 600 hours, which is feasible if the diesel is clean, but regular oil sample testing is necessary to monitor impurities. When purchasing from Taobao or professional stores, choose reputable sellers and check anti-counterfeit codes to avoid fake products. Replacement is simple: first drain the old oil, clean the connections, then install the new filter—hand-tightening is sufficient. Pay attention to the working environment; for example, in dusty mining conditions, opt for Premium-grade filters for enhanced protection and smoother engine operation. In summary, standard brands like Donaldson are preferred, but compatible options like Baldwin can balance maintenance costs and performance.
