Repairing or upgrading the tilt mechanism on your Aeron chair can seem daunting, but with the right tools and instructions, it is a task you can complete on your own. This guide from OfficeLogixShop walks you through the step-by-step process of installing a Tilt Cable Mechanism to fix common issues or upgrade your chair to a "Fully Loaded" version.
Tools You Will Need
- Hexagonal head bit (Allen key)
- Power drill
- Replacement gears and tension cables
1. Remove the Seat
- Locate the four screws securing the seat to the frame.
- Use a hexagonal head bit and power drill to remove these screws and lift the seat away to expose the mechanism.
2. Access the Tilt Mechanism
- Tap the front of the tilt mechanism housing to remove the top cover.
- Pull down the bottom cover to fully expose the internal gears and springs.
3. Update or Replace the Gear (Pre-2012 Models)
- For chairs manufactured before 2012, check if the internal gears need an update to be compatible with modern cable sets. Remove old gears as needed for the upgrade.
4. Replace the Clicking Part on the Right Side
- Unclip the silver stopper and loosen the tilt adjuster.
- Unhook the spring, remove the broken or basic gear, and insert the new replacement gear.
- Reattach the silver washer and re-hook the spring to the gear.
5. Replace the Gear on the Left Side
- Repeat the process on the left side of the mechanism, ensuring the spring is correctly hooked to the new gear for proper tension.
6. Attach the Tension Cables and Install the Adapter
- Connect both tension cables to their respective gears on the left and right sides.
- Insert the tension adapter into its designated spot on the chair frame and secure it using a hexagonal screw.
7. Attach the Control Handles
- Firmly press the control handles onto the tension mechanism. You may need to tap them into place for a secure fit.
- Note: To enable forward tilt, lean back slightly and pull the right control lever up.
8. Reassemble the Chair
- Click the bottom housing case back into position, followed by the top cover.
- Place the seat back on the frame. Start the four screws by hand to ensure alignment, then tighten them securely with your drill.
