29558331 Oil suction filter element Allison spare parts

29558331 Oil suction filter element Allison spare parts

The Allison 29558331 oil suction filter is a genuine Allison transmission filter component, precisely adapted to Allison 1000/2000/3000/4000 series heavy-duty automatic transmissions. It is also compatible with the hydraulic systems of transmissions from brands such as Mercedes-Benz, DAF, and Peterbilt. As the “first line of defense” in the transmission hydraulic system’s oil suction stage, its core function is to be installed at the oil pump’s suction port, efficiently intercepting larger impurities such as metal shavings and dust particles in the oil. This prevents impurities from being sucked into the pump, thus preventing pump wear, valve sticking, and oil circuit blockage, ensuring the hydraulic system’s oil suction efficiency and stability. Widely used in heavy-duty scenarios such as long-haul freight, mining operations, urban public transportation, and construction projects, it boasts strong adaptability, high filtration efficiency, and durable structure, making it the preferred replacement part for genuine factory maintenance. It perfectly meets the oil suction filtration needs of heavy-duty transmissions, showcasing the high-quality advantages of Allison genuine parts.

Product Advantages

1. Original factory compatibility, easy installation: 100% compatible with Allison 29558331 original factory specifications, with precise size and interface correspondence. It can directly replace the old filter element without modifying the installation structure or hydraulic pipeline. Its compatibility covers the oil suction filtration needs of commercial vehicles, construction machinery and other scenarios, and its compatibility is better than ordinary general-purpose oil suction filter elements.
2. Precise coarse filtration protects the core components: The 80μm precise coarse filter can efficiently intercept larger mechanical impurities and metal debris in the oil suction process, preventing impurities from being sucked into the oil pump and causing wear and jamming. At the same time, the folded design increases the dirt holding capacity and filtration area, ensuring smooth oil suction and providing reliable protection for the core components of the hydraulic system.
3. Durable, stable and reliable: Stainless steel filter media + carbon steel frame, excellent corrosion resistance and impact resistance, can withstand negative pressure and pressure fluctuations in the oil suction process, high temperature resistance and aging resistance, verified by heavy load cycle conditions, long service life, can effectively extend the filter element replacement cycle, reduce equipment maintenance costs, and is suitable for heavy load and high frequency use scenarios such as mining and long-distance freight.
