Makita 454316-9 Motor Housing HR4013C Rotary Hammer

Product Description

The MAKITA 454316-9 is a factory replacement motor housing designed for the HR4013C rotary hammer. The motor housing is the primary structural shell that encloses and protects the motor assembly, keeping internal components aligned and shielded from jobsite debris and impact. This is an OEM-sourced service part used by tool repair technicians and authorized service centers when the original housing is cracked, broken, or damaged beyond repair. Proper fitment of the motor housing is critical to maintaining motor alignment, airflow, and overall tool integrity.

The 454316-9 motor housing is specific to the MAKITA HR4013C rotary hammer, a professional-grade corded rotary hammer commonly used in concrete drilling and chiseling applications on commercial and residential jobsites. This part is typically installed during depot-level or field repairs when the outer housing sustains physical damage. Replacement restores the tool to factory structural specification.
