To prevent potential damage from anti-static electricity, you should discharge yourself first.

This can be done by simply touching a grounded metal object, such as a radiator.

Installation Process 1 – Make sure the iMac is

completely shut down and

switched off. Disconnect any

cables.

2 – Starting on the left of the

display, near the power button,

insert the pry tool into the gap

between the glass panel and the

rear case. (Insert no more than

3/8” into the display).

3 – Run the pry tool up the side just

enough to create a gap for the

Guitar pick tool.

4 – Slowly work the removal tool all

along the edges of the iMac –

taking care not to push it too deep.

The corners may be tricky and need

a few goes.

5 – Take care around the camera at

the top.

6 – Continue around the iMac until

you reach the end of the other

side.

7 – Lay the iMac down on the

workspace and attach the suction

cups to the top left & right corners

of the glass.

8 – Run the guitar pick tool around

the edges around, just to check you

have removed all the adhesive.

9 – Lift up the glass using the

suction cups, until you can see the

cables inside.

10 – While holding the display up

with one hand, use the other to

unplug the display power cable.

11 – Flip up the metal retaining

bracket on the display cable.

Disconnect the display cable.

12 – Lift the display up to a near-

vertical position. At this point,

there is a strip of adhesive along

the bottom of the display – you can

work this loose by moving the

display up and down a few times.

13 – Be very careful not to touch

the capacitor leads or any exposed

solder joints on the back of the

power supply.

14 – Lift the display up from the

frame and remove it from the

iMac.

15 – Remove the 2 T10 screws

from the left speaker.

16 – Unplug the left speaker cable

from its socket on the logic board,

De-route the cable from the gap

between the hard drive and logic

board.

17 – Use a pry tool to disconnect

the power button connector from

its socket on the logic board.

18 – Lift the speaker straight up,

until the power button cable is

exposed (about 0.5”).

19 – Gently de-route the power

button cable from its groove in the

left speaker.

20 – Lift the speaker straight up

and remove from the iMac.

21 – Pull straight up on the SATA

data/power cable to disconnect it

from the drive.

22 – Remove 2 T10 screws securing

the left hard drive bracket to the

rear case.

23 – Grab the hard drive and left

hard drive bracket together. Tilt the

left side up away from the rear

case and slide the assembly to the

left. Remove the hard drive and left

hard drive bracket from the iMac.

24 – Remove the left hard drive

bracket.

25 – Peel up any adhesive

remaining around the edge of the

iMac and display.

26 – Remove the screws from the

side of the hard drive, using the

Torx T8 screwdriver.

2.5” to 3.5” converter bracket. You

can now attach the T8 screws you

removed from the old drive, to the

new bracket ensemble.

28 – Attach the SATA connector on

the cable to the connector on the

drive. Flip the drive over. Remove

the backing that covers the

adhesive strip on the sensor and

stick the sensor to the back of the

SSD.

29 – Slide the old hard drive bracket onto the SSD ensemble. Insert the SSD into the space

on the iMac, lining up the Torx pins with the grommets in the iMac.

30 – Secure the old hard drive bracket with the Torx T10 screws.

31 – Attach the iMac SATA cable to the cable on the SSD. Arrange the cables so they lay

flat, to the side.

32 – Reattach the speaker that you removed earlier.

33 – Replace the adhesive that

holds the display in place. Make

sure you leave a gap for the camera

at the top. For the bottom each,

you will only need strips in the

corners and centre.

34 – Set the display on the bottom

edge, but don’t close it yet, as need

to connect the video cables.

36 – Carefully lower the display

into place.
