3M 7010326861 Output Spindle for 28773 Polisher

Product Description

The 3M 7010326861 is a replacement output spindle designed for use with the 3M 28773 7 inch to 9 inch polisher. The output spindle is a rotating drive component that transfers power from the tool motor to the backing pad and attached abrasive, making it a critical part of the polisher's mechanical drive train. When the original spindle shows wear, damage, or thread failure, this OEM-style replacement restores full drive function. Installation is typically performed by a trained tool repair technician or experienced end user comfortable with power tool disassembly.

This output spindle is intended as a direct replacement part for the 3M 28773 polisher, a tool used in automotive refinishing, marine finishing, and surface preparation applications where 7 inch to 9 inch pads are standard. The part is sold individually and is suited for shop environments that maintain their own tool inventory and perform in-house equipment repairs to minimize downtime.

• Designed specifically for the 3M 28773 7 inch to 9 inch polisher platform

Installation Notes

Disconnect and de-energize the polisher completely before beginning any disassembly. Output spindle replacement on rotary and random-orbit polishers typically requires basic hand tools and familiarity with power tool drive train components. Refer to the 3M 28773 service documentation for proper disassembly sequence and torque guidance. If in doubt, route the tool to a qualified power tool repair technician.
