-
-
Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear enclosure.
-
-
-
Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.
-
Run the tool up along the left side of the display.
-
-
-
Continue along the top of the display.
-
You may want to run the tool back and forth through what you've already cut a few times, to ensure you get as much of the adhesive separated as possible.
-
-
-
Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.
-
-
-
Gently twist the plastic card sideways to create a gap between the display and frame.
-
Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4".
-
-
-
Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.
-
-
-
Wedge the plastic card into the top right corner once again and let it stay there to keep the adhesive from resettling.
-
-
-
Insert a second plastic card into the gap between the display and frame located at the top left corner of the iMac.
-
-
-
With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case.
-
Begin to lift the top of the display up from the frame.
-
-
-
While holding the display up with one hand, use the other hand to unplug the display power cable. Make sure that you pull the cable out from the plastic tab, and not by pulling on the color wires.
-
-
-
Use the tip of a spudger to flip up the metal retaining bracket on the display data cable.
-
Carefully pull the display data cable from its socket on the logic board.
-
-
-
Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.
-
Repeat this step with the other adhesive strip and remove it.
-
-
-
Lift the display up from the frame and remove it from the iMac.
-
It may be necessary to slowly lift from one side, to peel against the remaining adhesive.
-
-
-
Use the tip of a spudger to flip up the metal retaining bracket securing the camera cable connector to the logic board.
-
-
-
The camera cable is connected to the rear enclosure via adhesive. Gently peel and remove it from the rear enclosure.
-
To reassemble your device, follow these instructions in reverse and use our Adhesive Strips Guide to reattach the display glass.

This guide contains many extra steps for what should be a straight forward, simple parts replacement without disturbing more than the display, left hand speaker and removal of 4 logic board screws for play. Nothing else except for the left hand speaker wire & iSight cable from logic board, the lower support bracket and loosening the speaker so as to move it around a bit.
For the ram, I bent a pair of cheap tweezers long ago supplied with these replacement kits to the perfect angle for holding, locating and inserting the ram into the slots under the logic bd after moving each retainer w/spudger and popping out the old. Pay attention to the orientation of the ram when removing/inserting the ram! An automotive mirror is handy along with a small flashlight for closeups. Once the ram is aligned properly substitute your fingers for the tweezers, ease it into the slot, push up & engage! Reinstall screws and all else. I have done this job successfully this way countless times. For a tweezers pic contact me!

Additionally, if a blade is present, I install the OSx system on the blade and everything else, apps and home folders on the new SSD. You get the very fast boot off of the blade and the full ssd for all else!
