Original Makita Spiral Bevel Gear — part no. 227641-9 (Spiral Bevel Gear 37). This genuine Makita gear is the large 37‑tooth spiral bevel used in the angle‑grinder gear train to transfer motor torque to the spindle.

Fits a number of Makita cordless brushless angle grinders (both 115 mm and 125 mm wheel sizes) — for example: DGA461 and DGA463 (115 mm), and DGA504, DGA506, DGA511, DGA513, DGA514 and DGA517 (125 mm).

This part meshes with the smaller spiral bevel pinion (227541-3) inside the gear housing and installs in the bearing/retaining‑ring assembly (retain‑ring R‑32 shown on the diagram).

 Sold as the individual genuine Makita gear for direct replacement in the gearbox — a straight swap to restore proper meshing and smooth power transfer in the models listed above.
