Makita Genuine 517649-4 Armature Assy 240 Volt for Makita GA4034,GA453,GA5034 Angle Grinders

The Makita 517649-4 Armature Assembly is a genuine OEM replacement part for 240 V Makita angle grinders, restoring full motor output when the original armature is worn, overheated, or has developed shorted windings. Built around a laminated steel core with tightly wound copper coils, the armature delivers efficient energy transfer and extended service life. The precision-machined commutator ensures stable current flow and reduces sparking, supporting proper brush seating and consistent performance during demanding grinding and cutting applications. The assembly arrives with a factory-fitted cooling fan to manage heat during continuous use, and the correct drive pinion profile for positive engagement with the gearbox. Dynamic balance is maintained to minimise vibration, keeping cuts accurate and controlled — exactly what contractors and tradespeople need when running tools hard on site. Specified to OEM No. 517649-4, this is an exact-fit replacement for compatible Makita 240 V models including the GA4034, GA453, and GA5034 angle grinders. It maintains the correct clearances and balance within the motor housing, ensuring the tool performs to its original specification after repair. Installation is straightforward with standard workshop tools, minimising downtime between jobs.
