Makita 619164-5 Spare Part - ARMATURE BDF441/BHP441
Makita part 619164-5 — Original Makita armature (rotor) for 14.4 V cordless combi/drill‑drivers. This is the rotating motor rotor assembly: laminated steel core with precision-wound copper coils and a plated commutator that interfaces with the carbon brushes to turn electrical energy into smooth, balanced mechanical drive. Replacing a worn armature restores torque and speed, reduces brush sparking and overheating, and gets a tired motor running quietly and consistently again.
Key details
- Manufacturer part number: 619164-5 (original Makita rotor/armature).
- Intended for 14.4 V Makita cordless combi/drill‑driver motors (precision fit to the motor housing, commutator and shaft interfaces).

When to replace
- Noticeable loss of power under load, heavy sparking at the brushes, excessive motor noise or overheating are typical signs the armature is worn and should be replaced. Installation is a direct motor swap when used with the matching brush holders, bearings and motor housing from the same model.
