Rotor Gear Washer 8V-71

Part No.:  420-0016
RBS on FaceBook
8V-71 blower rotor gear washer. RBS stocks heat treated steel rotor gear washers that will work with V-series gears. These have the industry standard .750" bolt hole and will make a register for the blower coupler to register into the rotor gear so everything runs concentric and doesn't burn up snout bearings or seals.

These are designed to be used with roots blowers with V-series gears and can be used with a 4-71 to 16-71 and will help provide proper bolt torque that stock GM washers can't provide.
