29556870 SealAssembly,Oil. Allison spare parts

Allison 29556870 SealAssembly, Oil is an original equipment manufacturer (OEM) oil seal component specifically designed for Allison transmissions. It is precisely matched to Allison 1000/2000/3000/4000 series heavy-duty automatic transmissions, and is also compatible with commercial vehicles and construction machinery from brands such as Mercedes-Benz, DAF, and Peterbilt that use Allison transmissions. As a core sealing component of the transmission oil system, its core function is to provide a tight seal through a precision sealing structure at oil line interfaces, transmission housing joints, and oil chamber sealing points, preventing oil leakage and blocking the intrusion of external dust and moisture. This avoids oil loss, insufficient lubrication of internal components, corrosion, and wear. It is widely used in heavy-duty scenarios such as long-haul freight, mining operations, urban public transportation, and construction projects. With its strong adaptability, tight sealing, and wear resistance, it is the preferred replacement part for OEM maintenance and repair, perfectly meeting the oil sealing requirements of heavy-duty transmissions.
