29545370 Planetary Carrier Assembly Allison spare parts

The Allison 29545370 planetary carrier assembly, as a core component of the original planetary gear mechanism of Allison transmissions, focuses on solving the core needs of power transmission, speed reduction and torque increase, and stable support of planetary gears. It is widely used in the planetary gear units of the transmission systems of Allison’s full range of heavy-duty automatic transmissions and various heavy commercial vehicles, engineering and mining machinery. The products strictly adhere to the original manufacturer’s production standards, with full-process quality control from the selection of 42CrMo alloy steel ingots, precision forging, normalizing and tempering treatment, five-axis precision milling, ion nitriding strengthening, planetary gear shaft press-fitting, and overall dynamic balancing testing, to hardness testing, wear resistance testing, and load-bearing capacity testing. This eliminates problems such as planetary carrier deformation, cracking, and excessive wear caused by forging defects, insufficient machining precision, and improper heat treatment. The products precisely support the planetary gears to complete their rotation and revolution, achieving power splitting and transmission with a transmission efficiency of 97%-99%. They are suitable for complex working conditions such as heavy loads, high-frequency shifting, severe vibration, and temperatures ranging from -40℃ to 180℃, and comply with the processing and quality standards of GB/T 3077-2015, GB/T 1184-2008, ISO 9001, and CE.
