Steps for Replacing Arm Yokes:

Dismantle the Existing Arm Yokes:
- Unscrew the two bottom screws beneath each arm pad. Use a wrench to remove all parts located beneath the arm pad and set them aside.
Identify and Remove the Old Arm Yokes:
- For the left arm yoke (with two levers), detach the levers. Note the differences between the newer and older lever versions for safe removal.
- Unscrew and remove the old left arm yoke.
Install the New Arm Yokes:
- Position the new arm yoke and screw the mechanism back in place.
- Reinsert the arm mechanism parts in the exact order they were removed. Ensure the arm index is correctly aligned for the side you're working on.
Reassemble the Chair:
- Securely attach the arm pad with the bottom screws.
- For the right arm yoke, repeat the process of dismantling and installing, mirroring the steps taken for the left arm yoke.
- Reattach the seat mechanism cover, ensuring the correct version is used and the teeth are snapped into their slots.
- Reinstall the seat by attaching the seat links to the mechanism cover, inserting the mechanism bolts, and tightening them. Follow the same process with the seat bolts.
- Finally, reinstall the back of the chair by placing it in position and securing it with the four screws.
