318051-2 supersedes older part numbers: 317814-3

Original Makita Gear Housing (part no. 318051-2) — a direct replacement gear head for 115–125 mm angle grinders. Made from hard‑wearing die‑cast aluminium to support and protect the bevel gears and bearings, it restores correct gear alignment and heat dissipation so the tool runs smoothly again. Fits a range of Makita grinders (examples: BGA450, BGA452, DGA450, DGA452, 9554NB, 9557NB, 9558NB) and supersedes earlier part number 317814-3; sold individually and installs using the tool’s existing fasteners and seals.
