Pachinko Rubber Rebound Bumper Removal

Grasp the rubber and plastic. You may be able to pull the part straight up, or rock it back and forth while lifting it up. If that doesn't work you can pry it up with techniques similar to those shown below.

 

Here we are putting something under the rubber to put pressure to raise the nail a little. You just want to raise the nail enough so you can then push the plastic back down and grab the nail head with pliers or another tool and pull the nail straight up. When you do this, hold the plastic down as you pull the nail up.

 

Here with the nail up we can get a tool under the head and lift the nail up.
