Description
Overview:
The Makita Spiral Bevel Gear 16 GA7020 - 227488-1 is a genuine replacement gear for selected Makita angle grinders. It is a precision‐machined steel spiral bevel gear that transmits drive from the motor to the output spindle through the grinder's right‐angle gearbox. This component helps maintain smooth, quiet running under load and restores correct power transfer when the original gear shows wear. Built for accuracy and long service life, it is suitable for both site and workshop use. As an OEM part (MPN 227488-1), it provides the correct fit and mesh without adjustment. Designed for Makita GA7020 and GA7020S platforms, it is an ideal choice when refurbishing the drivetrain during scheduled maintenance or after gearbox noise, vibration, or visible tooth damage.
