This swing motor frame assembly serves as the structural mounting housing and planetary gear carrier for the hydraulic swing motor on Daewoo Doosan DH220-5 series excavators. Designed to integrate with Toshiba M2X150 or M2X170 axial piston motors and Kawasaki equivalent units, the assembly includes the first-stage and second-stage planetary reduction gearsets, output pinion shaft, and wet multi-disc parking brake housing. Manufactured to OEM specifications for direct bolt-on installation to the swing bearing and upper structure. Compatible with Doosan DB58T and DB58TIS 6-cylinder diesel engines powering DH220-5, DH225-7, and Solar 220LC-V models. The frame assembly undergoes heat treatment and precision machining to withstand high torque loads and shock loading during slewing operations in construction and mining applications.
