Hitachi 2024084 Swing Device Shaft Housing

This swing device shaft housing serves as the vertical shaft base for the swing gearbox assembly on Hitachi EX60 series mini excavators. It is manufactured from high-strength cast iron to withstand the torsional loads and impact forces generated during slewing operations. The housing features a maximum outer diameter of 294 mm and an overall height of 146 mm. It incorporates 10 mounting holes for attachment to the swing frame and 8 gear holes for planetary gear engagement. The component is a direct replacement for OEM part numbers 2024084, 203026, and 4397254 across multiple EX60 variants including EX60-1, EX60-2, EX60-3, and EX60-5 models. Precision machining ensures proper alignment of the swing motor pinion and planetary gear set, maintaining swing torque delivery and reducing wear on the slew bearing.
