Pull the back cover and detach it from the chair. In the same way, you need to pull the front cover to remove it. 

Step 6 – Removing The Tilt Housing And The Cable From The Actuator

To remove the tilt housing, detaching the director is a must. Then release the two snaps and lift the director from the tilt housing to separate it from the assembly.

Now release the snap present below the cable to lift the cable. Once you have to lift the cable, you need to remove it from the actuator. Now slide out the cable to detach it from the actuator. 

Step 7 – Remove The Handle From The Swing Arm

To remove the handle from the swing arm, you need to lift up the lever and then release the bottom snap. Remember, you need to be extremely cautious, or you might break the handle. Release the bracket so that it comes out of the socket.

Step 9 – Remove The Leaf Spring From The Assembly

Now simply rotate the casing to remove the leaf spring. You need to pull it in an upward direction, and you need to be very careful so that it does not break. 

Step 10 – Remove The Pivot Pin And The Bushing

Take the T40 Torx Bit and remove the pivot pin. You will notice it is a bit lengthier, so slowly put it outwards. Then remove the other pivot pin joint just following the previous step. 

Then simply pull the bushing out of the assembly. Detach the tilt casting from the chair. You should use the hammer and punch to tap out the busing so that the B-link is removed. 

Use the same procedure to remove the bushing from the other side and detach the B-link from the chair. Then use the T25 Torx Bit to take off the cassette bolts. After removing all five cassette bolts, detach the tilt cassette. 

Use the hammer and the punch with a recess in order to remove the tilt housing. But before that, you need to hold the tilt casting and lift the entire unit in the air before hammering.
