Makita 638914-9 — Brush Holder (complete)
Restore reliable motor contact with this genuine Makita brush holder assembly (part no. 638914-9). The pre-assembled unit houses the carbon brushes and spring retainers in a heat‑resistant moulded frame with durable metal contact plates to keep steady pressure on the commutator and reduce sparking and intermittent power.
Direct-fit for Makita reciprocating saws in the BJR181 / DJR181, so you can replace the worn holder quickly and get the tool back to full performance.
Accepts the standard BJR181 brush inserts (around 7.0 mm × 10.5 mm), and installs with the small pan-head screws called out in the diagram (M3 × 8 mm). This makes swapping brushes and the holder straightforward during a routine motor service.
This is an original, genuine Makita item built to the same fit and finish as the factory component — a simple, long-lasting repair part that’s part of the Makita parts range for the BJR/DJR series and ideal when the tool shows heavy sparking, loss of power, or intermittent operation.
What you get: one complete brush holder assembly (638914-9), ready to fit; no extra machining or modification required — just remove the cover, replace the worn holder and brushes, and reassemble.
