3M 7000119157 Rotor Vane Set Disc Sander Die Grinder

Product Description

The 3M 7000119157 is a replacement rotor vane set containing 4 vanes, designed to restore proper airflow and rotation performance in pneumatic rotary tools. Rotor vanes are wear components inside air-powered motors that contact the cylinder wall during operation. As they wear, tool speed and torque drop. Replacing them with OEM-spec vanes brings the tool back to rated performance. This set is sold as 4 vanes, matching the vane count in compatible 3M pneumatic tool motors. Installation is performed by tool repair technicians or experienced tradespeople comfortable with pneumatic tool disassembly.

This rotor vane set is a service part for 3M pneumatic disc sanders, die grinders, and cut-off wheel tools. It is used during scheduled maintenance or when a tool shows reduced speed, rough running, or loss of power due to worn vanes. Consult the applicable tool owners manual and parts list schematic to confirm vane count and fitment before ordering. This part is sold individually as a set of 4 vanes.
