3M 7000043374 Motor Vane Orbital Sander

Product Description

The 3M 7000043374 is a replacement motor vane designed for use in pneumatic random orbital and orbital sanders. The motor vane acts as the blade inside the rotor assembly that catches compressed air and drives rotor rotation. A complete rotor assembly contains five vanes. When vanes wear or break, air motor performance drops and tool speed becomes inconsistent. This part restores proper airflow-driven rotation and brings the tool back to correct operating speed. Installation is straightforward for any technician familiar with pneumatic tool teardown and reassembly.

This motor vane is used across the line of 3M random orbital sanders and orbital sanders. It is a common wear item in production, finishing, and surface preparation environments where pneumatic sanders run for extended periods. Shops running high-volume sanding operations should keep replacement vanes on hand to minimize downtime during routine motor rebuilds.

Key Features

• Direct-fit replacement for worn or damaged rotor vanes in 3M pneumatic sanders
• Five vanes required per rotor assembly for full motor rebuild
• Restores consistent rotor speed and air motor efficiency
• Sold individually, allowing replacement of single vanes or a full set

Compatibility

Designed as a replacement motor vane for use on all 3M random orbital sanders and orbital sanders, as stated by the manufacturer.

Installation Notes

Pneumatic tool repair should be performed by a qualified tool technician. Disconnect the air supply and depressurize the tool completely before disassembly. Follow the tool manufacturer's service documentation for rotor housing removal and vane replacement sequence. Inspect the rotor cylinder bore and end plates for wear before reinstalling new vanes, as a worn bore will cause premature vane failure.
