I just did another bearing mod on a DX7. This time, I took photos

So presented here are step-by-step instructions for performing the mod. If you do this please take your time and be careful. Plenty here to mess up if you're not.

Let's begin ...

Remove and unplug the battery. Remove the six screws that hold the case halves together and seperate. There is a small PCB with the battery connector on the back case half with wires going to the circuit board in the front case half, so don't pull.
