23017225 Gasket Allison spare parts

The Allison 23017225 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 23017225
– Material Specifications: High-quality asbestos-free rubber sheet or metal-coated composite material (aramid fiber reinforcement + nitrile rubber bonding/SPCC metal substrate + nitrile rubber coating layer) is selected, strictly adhering to GB/T 539-2018 and GB/T 12621-2021 standards. It features an asbestos-free environmentally friendly design, tensile strength ≥12MPa, Shore hardness controlled between 65-75A, dense material without pores or damage, and strict control over impurity content. The surface undergoes precision grinding, achieving a roughness of Ra≤0.4μm.
– Dimensions: Length 50-180mm, Width 30-120mm, Thickness 0.4-1.2mm (adaptable to different gap requirements), Positioning hole diameter φ6-12mm, Hole spacing error ≤0.02mm, Dimensional tolerance controlled within GB/T 1804-2000 m-level accuracy, Fitting gap ≤0.01mm
– Performance specifications: Temperature resistance range -40℃ to 220℃; oil resistance grade conforms to GB/T 1226-2010 standard; sealing pressure ≥1.5MPa; compression set ≤15%; compression resilience ≥40%.
– 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.

Core product advantages:

1. Precise Original Factory Fit: Strictly matches the original Allison 23017225 part number, requiring no hole modification or adapter, and can be installed directly in the original position.
2. Excellent sealing and leak prevention: It adopts asbestos-free rubber sheet or metal-coated composite material (aramid fiber reinforcement + nitrile rubber bonding), and the material is dense and non-porous.
3. High temperature and oil resistance, durable: It can adapt to the high temperature and high pressure working environment of the gearbox, and there is no aging or deformation under high temperature; it can withstand the corrosion of various gearbox oils and hydraulic oils, and there is no expansion or leakage after immersion for 72 hours, and the sealing performance is not reduced.
4. Easy and practical installation: The one-piece molded structure has reserved precise positioning holes. The holes are chamfered to remove burrs. No complicated tools are required, and one person can quickly complete the installation and disassembly.
5. Environmentally friendly and controllable quality: 100% asbestos-free and environmentally friendly design, with no harmful components, suitable for scenarios with high environmental protection requirements, and is an ideal alternative to asbestos gaskets.
