As an original equipment manufacturer part, this transmission assembly is structurally designed to be highly compatible with the corresponding loader model, capable of withstanding the load impact of high-intensity operations. It reduces power loss through a reasonable gear ratio distribution and, through its own transmission buffering effect, reduces wear on the engine and other transmission components, extending the overall service life of the loader and minimizing operational interruptions due to transmission failures. It is well-suited for long-term operation in complex conditions such as construction sites and mines.
