Replacing the hard drive requires separating the display and removing the left speaker.
This guide also includes steps to upgrade your iMac's hard drive with a SSD. It describes how to install the SSD's temperature sensor so that the Mac's fans will operate at the correct speed.
Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.
Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply.

Инструмент, используемый на этом этапе:iMac Intel 27" Cardboard Service Wedge$4.99
-
With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed with the iMac laying down, but are faster and easier with an iMac service wedge.
-
If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.
-
-
-
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 case.
-
-
-
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.
-
-
Инструмент, используемый на этом этапе:Plastic Cards$2.99
-
Set the iMac face-up on a table.
-
Starting from the top right corner of the iMac, insert a plastic card between the display and frame.
-
-
-
Gently twist the plastic card to open the space between the display and frame, and cut any remaining adhesive near the corner.
-
-
-
Slide the card toward the center of the display, to cut any remaining adhesive.
-
-
-
Put the card into the corner again and let it stay there to keep the adhesive from resettling.
-
-
-
Insert a second card into the gap between the display and frame in the top left corner.
-
-
-
Gently twist the card, slightly increasing the space between the display and frame.
-
-
-
-
Slide the plastic card toward the center, again stopping just before the iSight camera.
-
-
-
With the cards inserted as shown near the corners, gently twist the cards to increase the gap between display and case.
-
If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the adhesive in the problem area.
-
Begin to lift the top of the display up from the frame.
-
-
-
While holding the display up with one hand, use the other to unplug the display power cable.
-
-
-
Flip up the metal retaining bracket on the display data cable.
-
Disconnect the display data cable.
-
-
-
Lift the display up to a near-vertical position.
-
Remove as much of the adhesive as possible by grabbing it at the outer edges, and then pulling or rolling it towards the middle.
-
-
-
If necessary, a plastic card can be used to cut any remaining sections of the bottom adhesive strip.
-
-
-
Lift the display up from the frame and remove it from the iMac. Lay the display face down on a flat, soft surface.
-
It may be necessary to slowly lift from one side, to peel against the remaining adhesive.
-
-
-
If there is a wire or cable underneath adhesive tape, always pull the tape off first.
-
If the cable is glued to the chassis, use a heated iOpener or a hair dryer to soften the adhesive first. You can then slide an opening pick underneath the cable to loosen it. Never pull directly on the delicate connectors.
-
Slide an opening pick underneath the foam cushion pieces to separate them from the display, and gently pull them off. You may need some double sided tape to re-attach them to the new display.
-
-
-
Unplug the left speaker cable by pulling it straight up out of its socket on the logic board.
-
De-route the cable from the gap between the hard drive and logic board.
-
-
-
Use a spudger to disconnect the power button connector from its socket on the logic board.
-
-
-
Lift the left speaker straight up, until the power button cable is exposed (about 0.5 inches).
-
-
-
Lift the left speaker straight up and remove it from the iMac.
-
Push from the connector end as you pull from the speaker end to thread the cable under the hard drive's right bracket.
-
-
-
Pull straight up on the SATA data/power cable to disconnect it from the drive.
-
-
-
Remove two 7.3 mm T10 screws securing the left hard drive bracket to the rear case.
-
-
-
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.
-
-
-
Remove the four 8.1 mm T8 screw posts from the hard drive, and transfer them to the replacement drive enclosure.
-
-
-
Depress the enclosure's front plate latch with your finger. While holding the latch down, swing the plate out.
-
Remove the front plate.
-
-
-
Line up the small SATA connector so that the short side on the SSD connector matches the short side on the enclosure connector.
-
Slide the drive in through the front of the enclosure until the SATA connector is fully seated.
-
-
-
You may optionally install two Philips #1 screws that came with the enclosure kit to secure the SSD in the enclosure.
-
Replace the front plate.
-
-
-
Peel the backing off of the adhesive back of the small temperature sensor board.
-
Adhere the temperature sensor board to an exposed, metal area of the surface of the SSD, as close as possible to the SATA connector.
-
Fold the excess temperature sensor wires so that they are out of the way while you install the enclosure.
-
-
-
Install the mounting pins from the old hard drive onto the sides of the enclosure.
-
-
-
Attach any mounting brackets removed from the old hard drive onto the enclosure.
-
-
-
Attach the iMac's SATA-combo cable to the new temperature-capable SATA-combo cable.
-
Route the SATA cables where they will not interfere with any other components.

My experience in upgrading this unit to a Seagate 4TB hybrid ST4000DX001 went fine except for the fans running at a constant higher RPM. Using Macs Fan Control is solving my issue for now. As a tip, you do not need to remove the left speaker, you can loosen the two screws and angle it leaning to the left.
What setting do you change in Macs Fan Control? Im looking at getting a SSD fitted to my Late 2013 iMac by a certified repair centre who have said they will do it for me if I provide the SSD but they did mention that the fans would most likely speed up as there won't be a temp sensor in the SSD. Thanks.

I didn't have a fan problem, since the adapter comes with a temperature sensor, my problem was the adapter wasn't long enough.
Lewis: simply running the Macs Fan Control app will do it. Otherwise the fans run at full speed because they have no temperature measurement.
I'm wondering what drive apple uses for the 1TB SSD version? Is it an OEM type PCIE Sandisk as well or a larger 2.5" drive?
I'm very tempted to upgrade my Fusion drive.
