Product Description

800302267 DB428 Transmission / Gearbox — for XCMG 300K / 300KS Series Wheel Loaders

The DB428 transmission (part no. 800302267) is the core power-shift gearbox of XCMG 300K(GH) / 300KS(GH) / 300KS(RD) / 300KS(SM) 3-ton wheel loaders, built on the Advance (Hangzhou Advance Gearbox Group) DB428 platform. It is an electro-hydraulically controlled power-shift transmission with 4 forward + 3 reverse gears, designed for separate mounting alongside the YJ315X torque converter to deliver smooth, reliable power transmission under heavy-duty construction and material-handling conditions.

In the XCMG 300K(T)-0201 transmission system, part 800302267 is listed as the primary "DB428 Gearbox" assembly, working in conjunction with torque converter 800302261 (YJ315X) and shift pump 803004135 to form the complete powertrain heart of the loader.
