Updating the main plates
The existing engraved portion on the belt can be peeled off and removed. It helps if you heat it up with a hairdryer just a bit first, but that is not mandatory. Any residual adhesive can be cleaned up with an alcohol wipe (included with new engraving). The new engraved plaque has a peel and stick adhesive on the back and you just line it up and stick it down onto the metal.
