207-26-00300 Swing Gearbox PC300-8MO Excavator Swing Reduction Assembly Original OEM
207-26-00300 swing gearbox assembly is a complete slewing reduction unit built for Komatsu PC300-8MO class excavators. The unit converts hydraulic motor output into high-torque swing motion, and every assembly is verified against the original part number before it leaves our warehouse so that installation time on site stays predictable.
Product Features
- Gears forged from alloy steel, carburized and quenched to HRC58-62 for wear and impact resistance under heavy swing load.
- Forced lubrication channels keep gears and bearings covered during continuous 360 degree slewing cycles.
- Cast iron housing resists deformation and keeps bearing bores aligned in dusty job site conditions.
- Every assembly is load tested and photographed before dispatch, with the inspection photos sent for confirmation.
