Introduction
A prerequisite for removing the logic board assembly.
Tools
-
-
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.
-
-
-
Insert a metal spudger into the slot at the bottom of the iPod just above the dock connector.
-
Use the metal spudger to pry up the bottom edge of the click wheel.
-
-
-
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.
-
-
-
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.
-
To reassemble your device, follow these instructions in reverse order.
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.
