Remove the large bolts located on the left and right hand side of the chair. These can be removed using a large adjustable wrench.
-
-
-
Next we need to unzip the front of the chair . do so by unzipping all zippers shown in this order. 1 on at top of chair and one at bottom, then one underneath the leather back-pad.
-
-
-
-
Now that the front of chair is open remove this small plastic bracket by removing the 2 screws.
-
-
-
The mechanism has a wire harness that runs down to the main PCB in the chair. Most of our 3D mechs come with a new harness pre-attached and the old harness will need to be disconnected from the quick disconnect .
-
Don't disconnect these if your new mechanism has them pre-attached.
-
This is an extremely vague photo , but the quick disconnect is located in the sheath on the lower left hand side of the chair . DON"T CUT THE SHEATHING JUST THE ZIP TIES . If you cant get this zip tied onto the frame like the factory had it no worries just make sure its secured in the general location with zip ties .

-
-
This is the entire upper harness that connects to the 3D mechanism .
-
Lower harness that connects to main PCB . see last step for location
-
Quick disconnect . located on frame .
-
-
-
Remove the 3 screws on the lower power box cover to gain access to the lower wire harness
-
unscrew the wire harness clip by removing the 2 screws
-
These marked connectors are the motor wires and these are not all of the wires on this harness. please see last step
-
-
-
Now lift up on chair piece and push forward. the chair piece should now be separated from the frame piece.
-
Next remove all 4 bolts on top bracket.
-
-
-
Now remove the upper limit sensor from the 3 plastic pins and move it aside away from the magnet. DO NOT UNPLUG IT
-
Put the chair into Manual Shiatsu and hit the zone button 2 times , sometimes 1 press. You will know you did it right because the arrows will light up in the middle.
-
Shows if your in shiatsu mode .
-
Once these arrows are glowing you can drive the the mech out the top of chair using the UP arrow.
-
-
-
Alternatively you can pop out this magnet instead of the sensor . either way manual shiatsu mode has to be used .
-
-
-
The new mech will not come with the plastic wheels , these will need to be transferred from the old mech to the new one. see photo for location of wheels.
-
-
-
If for some reason you cant get the mechanism into the chair due to the top axle blocking it . Its due to this 3D gear not being set at the correct angle.
-
To fix the angle simply remove this cover by removing the 2 screws and spin the motor belt until angle is correct.

-
-
New mechanism should be installed below you will see some quick tips and reminders during reassembly.
