Original Makita armature (rotor) assembly — part no. 516489-7. Designed to restore motor performance in Makita 190 mm circular saws, this rotor replaces a worn or burnt armature to get your saw turning true and under load again.
Key details
- What it is: armature / rotor assembly with integrated cooling fan.
- Drive: 9‑tooth drive shaft on the rotor.
- Voltage: intended for 220–240 V versions of the saw (240 V listings are common).
- Size note: fits Makita circular saws that use a 190 mm blade; aftermarket listings show a rotor length of about 159 mm (measure against your old rotor to confirm).
Example compatible models
- Makita 5704R (190 mm circular saw). Some service listings and parts breakdowns also reference the 5704RK variant; a number of compatibility listings include certain 5806-series models as well — verify by matching your saw’s model and the old rotor’s dimensions/drive.
Notes for replacement
- The armature is a motor component; when fitting a replacement it’s wise to check the condition of the motor brushes and bearings — some rotors are supplied without replacement bearings or brushes.
If your saw is a Makita 5704R, this original Makita part 516489-7 is the correct rotor assembly to restore the motor.
