Product Description

The 3M 7000118687 is a drop-in replacement motor assembly designed for the 3M Random Orbital Sander. Rather than rebuilding a failed motor from individual components, this unit allows a technician or repair shop to swap the complete motor assembly in a single service step. The drop motor design significantly reduces repair time and the risk of reassembly errors. Rated for a 3-inch pad with a 3/16-inch orbit, it restores the sander to original operating performance. At 1.55 pounds, the assembly is compact enough to handle without additional tooling and is sold as a single unit.

This motor assembly is intended for service and repair of the 3M Random Orbital Sander in professional finishing and body shop environments. It is the correct replacement for technicians who need to return a sander to service quickly without sourcing or pressing individual motor subcomponents. Typical install scenarios include production grinding and finishing lines, automotive body refinishing shops, and industrial MRO departments where sander uptime is critical.
