29541722 Hub, High-Range Clutch Allison spare parts

The Allison 29541722 high-speed clutch hub is precisely fitted to Allison 1000/2000/3000/4000 series heavy-duty automatic transmissions, compatible with heavy-duty commercial vehicles, mining wide-body trucks, engineering dump trucks, and long-haul tractors from brands such as Mercedes-Benz, DAF, Peterbilt, and Volvo equipped with Allison transmissions. As the core support and power transfer component of the high-speed clutch, it directly links with the high-speed clutch pressure plate, friction plate assembly, hydraulic actuator, and the high-speed gear rotation shaft of the transmission. During high-speed gear shifting, it synchronously transmits rotational power, ensuring precise engagement of the friction plate assembly and zero power loss. It provides stable positioning during disengagement, preventing uneven wear and abnormal noises. It is particularly suitable for demanding conditions such as long-distance high-speed cruising, heavy-load high-speed driving, and frequent high-speed gear shifting. With original factory design dimensions and zero installation precision deviation, it is the preferred original factory replacement part for high-speed clutch repair and fault replacement.

Core technical parameters

–Model: 29541722
– Product Name: Hub, High-Range Clutch
– Operating temperature: -40°C to +150°C (short-term peak 160°C)
– Product weight: 4.2 kg
– Compatible Systems: Allison 1000/2000/3000/4000 series heavy-duty automatic transmissions; compatible with high-speed clutch systems for heavy-duty commercial vehicles, mining trucks, engineering vehicles, and municipal vehicles. It can precisely link with Allison original high-speed clutch friction plates, steel plates, pistons, seals, and TCM control units to achieve smooth power transmission and precise clutch control in high-speed gears.
– Suitable operating conditions: long-distance heavy-load high-speed cruising, high-speed driving in mountainous areas, heavy-load high-speed transportation in mining areas, and high-frequency high-speed gear switching on urban expressways; can work stably in harsh environments such as high temperature (transmission oil temperature 120°C), low temperature (-40°C), high speed, high vibration, and hydraulic shock.

Product Advantages

1. Precise original factory fit, saving repair time: 100% matching Allison 29541722 original factory specifications, with zero error in splines, gears, dimensions, and mounting holes; can be replaced individually without disassembling the gearbox assembly, significantly reducing repair labor costs.
2. High-strength forging, torsional resistance and durability: The integral forging of chromium-molybdenum alloy steel with carburizing and quenching process results in a torsional strength of over 1100 N·m; it can withstand high-speed rotational impact and long-term heavy-load operation, and its service life is more than twice that of ordinary cast wheel hubs.
3. High-speed adaptation and precise transmission: The spline teeth are precision ground, and the tolerance of the friction plate positioning groove is controlled within 0.02mm; there is no uneven wear or jamming when the high-speed gear clutch engages/disengages, and the power transmission efficiency at high speed is as high as 98.5%; effectively reducing shift jerking, abnormal noise and power loss in high-speed gears, and improving high-speed driving comfort and gearbox operation stability.
