Introduction
A prerequisite for removing the logic board assembly.
What you need
-
-
Use a heat gun to soften the adhesive underneath the plastic bezel at the bottom of the iPod.
-
Use a plastic opening tool to pry the bezel from the case of the iPod and remove it.
-
-
-
Unscrew three screws from the bottom of the iPod:
-
Two 4.4 mm angled Phillips screws
-
One 5.4 mm Phillips screw.
-
Use a plastic opening tool to pry the metal retainer out from the bottom of the iPod and remove it.
-
-
-
-
Place a guitar pick between the click wheel and the case of the Nano and remove the metal spudger.
-
Pry up the edges of the click wheel with the guitar pick until the click wheel comes free from the case.
Use extreme care when inserting the metal plunger to lift up the click wheel. I ended up damaging one of the sensor pads and then needed to order a new click wheel circuit. Not very expensive to replace but I had not intended to replace this item and so my finished repair was delayed.

Lift the click wheel out of the way with one hand and use a plastic opening tool to pry the click wheel ribbon cable connector off its socket on the logic board.
-
Remove the click wheel.
In the second photo where you can see under the click wheel, just above the square black piece with the apple on it is a black rectangle with a hole in the center. There will be a spring in the hole. Remove the spring and the black piece it is in and set aside or they will fall out and get lost.

On the Nano I worked on I had to do steps 12-14 before step 10 because the metal plate on the bottom is one of the two things holding the click wheel in place.

You MUST remove the bottom plate BEFORE forcing of the wheel or you WILL tare it apart as there is a lug on the bottom plate that holds the wheel in place ( wish I had known this before I damaged mine)
also do not lose the very small spring that is under the wheel (I DID )

+1. There is a tiny piece of plastic containing a little spring just under the wheel. Remove thoses parts before extracting the main board or you will probably loose them.
