XB00003827 Transmission Shaft Bracket for ZW180-7

The part number XB00003827 you are inquiring about is the original transmission shaft bracket (also known as the intermediate support or hanger assembly) provided by Hitachi for the ZW180-7 wheel loader. This component is the core support part of the transmission shaft system, responsible for stabilizing and fixing the transmission shaft on the frame crossbeam. Its universal model may cover other similar models of the ZW180 series (such as ZW180-5, ZW180-6, etc.). It is strictly prohibited to use non original or mismatched brackets in size and strength, otherwise it may cause vibration, abnormal noise, increased wear of the transmission shaft, and even serious mechanical failures such as transmission shaft detachment.

This product is a transmission shaft intermediate support assembly, usually composed of a metal bracket, double row tapered roller bearings, rubber shock absorbers (bushings), and sealing components. Its main function is to support the middle section of the long transmission shaft, compensate for installation errors, and absorb vibrations and impacts transmitted by engine runout, frame deformation, and road bumps. For heavy equipment such as ZW180-7, the support body is usually forged or cast from high-strength medium carbon steel or alloy steel, and undergoes heat treatment to obtain good comprehensive mechanical properties (core toughness, surface wear resistance). The internal rubber damping components are crucial, and their material properties (such as natural rubber or silicone rubber) directly affect the vibration isolation effect, especially in low-temperature environments where a certain degree of elasticity needs to be maintained to prevent a sharp increase in stiffness from exacerbating vibration transmission. Bearings need to withstand the radial and axial loads caused by the high-speed rotation of the transmission shaft, and have a good lubrication and sealing structure.

Replacement cycle: The transmission shaft bracket itself, as a structural component, does not need to be replaced regularly without deformation or cracking. But its internal bearings and rubber shock absorbers are vulnerable parts. It is recommended to conduct a comprehensive inspection every 2000 working hours or annually, focusing on checking whether the rubber parts are cracked, aged, permanently deformed, and whether the bearings have looseness or abnormal noise.
