227505-7 supersedes older part numbers: 227465-3
Genuine Makita spiral bevel gear — part no. 227505-7 — 37-tooth sintered drive gear designed for the angle-grinder gear housing; replaces the original spiral bevel gear to restore smooth, quiet spindle rotation.
Fits a range of Makita 115 mm and 125 mm angle grinders, including models such as 9554NB, 9555NB, 9556NB, 9557NB / 9557PB and 9558NB / 9558PB — listed among Makita parts for those grinders.
Made by Makita as a sintered (powder-metallurgy) gear to preserve tooth profile and wear resistance, it’s a direct-fit replacement that installs in the standard Makita gear housing with common workshop tools — ideal when the gearbox shows noise, binding, or a non-rotating spindle.
