Original Makita Motor Housing — Part 450041-0

Replace a cracked or worn outer casing with this genuine Makita motor housing (part no. 450041-0), the exact motor/case assembly used on Makita SDS‑MAX rotary hammers. It’s a direct-fit motor housing for HR4501C / HR4510C / HR4511C models and is the factory-design housing that secures the field and armature, aligns the main bearings and provides the ventilation and mounting points required for proper motor cooling and mechanical alignment.
