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.
I ordered part that matched the model polisher I have and the one I received had the wrong size shaft I really needed to get this polisher working so I ordered a new on through Home Depot. Tossed my old one. Not reall happy
SHURHOLD MEANS QUALITY
Bought the 8100 polisher many years ago. I wax my boat twice a year and this is the first time I’ve had to replace the backing plate. I would say that is a quality product
LASTED A LONG TIME AND MUCH USE.
It was easy to remove the old one and screw in the new.
Awesome quick change no through bolts to worry about
