29554434 Filter Assembly Allison spare parts

29554434 Filter Assembly Allison spare parts

The 29554434 filter assembly is a core component designed specifically for the purification of Allison transmission fluid. It is precisely matched to the original factory installation standard and is widely compatible with Allison series transmissions and various commercial vehicles, construction machinery, and special vehicles. It is mainly used for the filtration and purification of hydraulic oil and lubricating oil in Allison transmissions. It works in conjunction with the transmission fluid circulation system and can efficiently filter out various impurities in the fluid, including debris generated by friction of metal parts such as gears and steel belts, fibers generated by wear of clutch friction plates, high-temperature aging products of plastic parts such as oil seals, as well as organic acids, coke and other impurities generated by high-temperature oxidation of the fluid [2][6]. It avoids impurities from clogging the oil circuit, wearing valve cores, and damaging transmission components, ensuring that clean fluid is supplied to all moving parts and solenoid valves of the transmission, playing a role in lubrication, cooling, cleaning and rust prevention, providing reliable guarantee for the smoothness of power transmission and the long-term performance of parts of the transmission, and meeting the stringent requirements of Allison transmission for fluid cleanliness.
This product features an integrated structure, encompassing a complete set of components including the filter element, filter housing, and seals. Its spin-on design fits seamlessly into transmission installation positions, facilitating easy assembly and allowing for complete replacement without complex tools. This significantly improves installation and maintenance efficiency, making it particularly suitable for routine maintenance and fluid changes in Allison transmissions.

Core technical parameters

-Part number: 29554434
– Material Specifications: The filter element is made of high-quality glass fiber filter media (high filtration accuracy, oil and corrosion resistant), and the filter housing is made of high-strength cold-rolled steel plate or aluminum alloy. It has built-in nitrile rubber (NBR) seals, which meet the GB/T 10125-2021 corrosion resistance standard. The filter media can withstand temperatures up to 150℃, and the filter housing has a tensile strength ≥150MPa.
– Structural parameters: Assembly diameter 75±0.5mm, height 120±0.5mm, filter element folding layer ≥30 layers, filtration area 0.3㎡[5], interface thread specification M30×2.0 (screw-on connection), sealing thickness 3mm, dimensional tolerance ≤±0.03mm, surface roughness Ra≤1.6μm, sealing gap after assembly ≤0.01mm.
– Compatible Models: Precisely compatible with Allison 1000/2000/3000 series transmissions, suitable for various commercial vehicles, construction machinery, and special vehicles equipped with this series of transmissions. It is also compatible with Allison transmission hydraulic oil and lubricating oil filtration systems, as well as other installation scenarios with corresponding specifications of oil filtration systems.
– Performance: Normal operating temperature 80-120℃, maximum tolerance temperature under extreme conditions ≤150℃, filtration accuracy 25μm[1][5], filtration efficiency ≥99.5%, dirt holding capacity ≥0.8kg, working pressure difference 0.05-0.3MPa, bypass valve opening pressure 0.4±0.05MPa, protection level up to IP65.
– Product weight: 0.65±0.03kg (standard weight per set, conforms to original manufacturer specifications, moderate size, convenient for bulk storage, installation and portability, without increasing the extra load on the equipment)
– Service life: Under normal working conditions, the overall service life is ≥6000 hours. The recommended replacement cycle for the filter element is every 60,000 to 120,000 kilometers (or adjusted according to working conditions) [6]. After running continuously for 1000 hours under high temperature and high pollution conditions, the filtration efficiency retention rate is ≥92%.
