Confirm that your polisher is OFF and UNPLUGGED. Using the wrench that was supplied with your polisher engage the backing plate nut and unscrew old backing plate. Reverse this process to screw on new backing plate.
2nd backing plate seems it might last longer than the first one.
Original one yellow foam disintegrated in a couple years….guess by design? New one looks the same, better hurry and use it!
I have several polishers and my shop building gets incredibly hot in summer. Plastic / rubber doesn't live long there. New plate is fine.
This is my second one, old one finally wore out.
Had to replace the backing plate for the dual action polisher. Love Shurhold products, they work great and are very easy to use. The videos they produce to show you how to use their products are very helpful as well!
