29549764 C3 Clutch Housing Allison spare parts

29549764 C3 Clutch Housing Allison spare parts

The Allison 29549764 C3 clutch housing, as a core component of the original clutch from Allison transmissions, focuses on solving the core needs of wet clutch chamber sealing, friction pair positioning, precise distribution of hydraulic oil passages, and resistance to torsion and deformation. It is widely used in the transmission assemblies of Allison’s full range of heavy-duty automatic transmissions and various heavy commercial vehicles and engineering and mining machinery. The products strictly adhere to the original manufacturer’s production standards, with full-process quality control from the selection of ductile iron raw materials, precision sand casting, isothermal quenching and strengthening, CNC milling and turning, precision machining of oil passage holes, precision milling of sealing grooves, and surface nitriding anti-corrosion treatment, to overall pressure testing, full dimensional inspection, and leakage detection. This eliminates problems such as clutch slippage, shifting jerks, hydraulic oil leakage, and component burning caused by shrinkage cavities in the housing casting, oil passage blockage, and insufficient sealing surface precision, significantly reducing maintenance frequency and costs. They are suitable for complex working conditions such as heavy loads, high-frequency start-stop, severe vibration, and oil temperatures ranging from -40℃ to 180℃, and comply with the processing and quality standards of GB/T 1348-2009, GB/T 9439-2010, ISO 9001, and CE.
