3M 7000118688 Random Orbital Sander Drop Motor

Product Description

The 3M 7000118688 is a complete drop-in replacement motor assembly designed for the 3M Random Orbital Sander. Rather than disassembling and rebuilding a worn or failed motor with individual components, this part allows a technician to swap the entire motor unit in one service step. The 5-inch orbit configuration matches the original specification, restoring the sander to factory performance. At 1.55 pounds, the assembly is a direct match for the motor it replaces. This part is intended for service technicians and shop professionals who maintain orbital sanding equipment in production, bodywork, or finishing environments.

This motor assembly fits the 3M Random Orbital Sander line and is suited for repair operations in automotive body shops, industrial finishing facilities, and woodworking production environments. It is appropriate wherever the 3M Random Orbital Sander platform is in active service and a full motor replacement is preferred over component-level rebuilding. Installation requires basic pneumatic tool service knowledge and access to manufacturer service documentation for the host sander model.
