N522052 supersedes older part numbers: N566476

Original DeWalt Gearcase Assembly — part N522052 — direct-fit replacement for the DeWalt DCM581 brush cutter (Type 1).

This Gearcase SA is the gearbox housing sub-assembly that contains and protects the drive gears and spindle interface; it’s supplied as the factory-matched housing with the correct mounting bosses and seal seats so it drops into the DCM581 chassis without modification.

If your cutter has a cracked housing, stripped mounting bosses, excess play at the cutting head, or grease/oil weepage from the gearbox, replacing the N522052 gearcase restores alignment and containment of the gearset to stop noise and premature wear. This genuine DeWalt part is the exact internal-fit component you’d choose when ordering parts for power tools to get the tool back to original fit and function.

This gearcase is listed specifically for DCM581 Type 1 tools.
