29544250 Gasket Allison spare parts

The Allison 29544250 gasket, as a core sealing and buffering component of Allison transmissions, is hailed as an “invisible barrier” for transmission sealing and protection. Its core function is to fill the joint gaps of components such as the transmission housing, valve plate, bearing housing, and cover plate, achieving sealing, buffering, shock absorption, and leak prevention functions. It prevents transmission oil leakage, blocks the intrusion of dust and impurities, and buffers high-frequency vibrations during equipment operation, avoiding wear and abnormal noise on component joint surfaces, ensuring internal cleanliness and pressure stability of the transmission, extending the service life of the entire machine, and reducing maintenance costs and downtime losses.

Core technical parameters:

-Part Number: Allison 29544250
– Material Specifications: Made of high-quality asbestos-free rubber sheet or metal-coated composite material, with an asbestos-free environmentally friendly design, tensile strength ≥12MPa, and Shore hardness controlled at 65-75A; the surface is precision polished to a roughness of Ra≤0.4μm, enhancing the fit and sealing performance.
– Structural type: Multi-layer composite molding structure (metal layer + flexible sealing layer). The metal layer bears the pressure and maintains structural stability, while the flexible layer fills in minor unevenness at the joint surface and improves the sealing fit. The functional layered design greatly improves sealing reliability and deformation resistance. Precise positioning holes are reserved on the surface; the edges are precisely cut to fit the joint surface size, ensuring a tight fit and no loosening after installation; some models are equipped with positioning pins to further improve installation accuracy.
– Dimensions: Length 50-180mm, width 30-120mm, thickness 0.4-1.2mm (adaptable to different clearance requirements), positioning hole diameter φ6-12mm, hole spacing error ≤0.02mm, dimensional tolerance controlled within GB/T 1804-2000 m-level precision, precisely matching the Allison gearbox mating surface dimensions, fitting gap ≤0.01mm, fully compatible with original factory installation requirements.
– Performance indicators: Temperature range -40℃ to 220℃; oil resistance grade meets GB/T 1226-2010 standard, can withstand corrosion from various transmission oils and hydraulic oils, no expansion or leakage after immersion for 72 hours, and no degradation of sealing performance; sealing pressure ≥1.5MPa, compression deformation rate ≤15%.
– Applicable Scenarios: Specifically adapted for Allison series transmissions, widely used in commercial vehicles, heavy trucks, construction machinery, mining equipment (such as the Allison transmissions in the Terex TR50/TR60 series), and other equipment equipped with Allison transmissions. It is used for sealing and buffering key parts such as transmission housing mating surfaces, valve plates, bearing seats, cover plates, and oil pans, undertaking the core tasks of sealing, leak prevention, buffering, and shock absorption. It can be used for original parts replacement, transmission repair and maintenance, and is suitable for complex working conditions such as heavy loads, high-frequency vibrations, heavy oil contamination, high temperature and high pressure. It provides sealing protection for the stable operation of internal transmission components and helps the equipment operate efficiently.
