For replacing the A18083 belt, you will mainly need a 3 mm Allen key to unscrew and tighten the screws on the support plate and the clutch button.

Remove the steering wheel drive unit.
Disengage the clutch.
Remove the front cover by pulling it upwards and away from the rear cover.
Use a 3 mm Allen key to unscrew and remove the two screws from the support plate, then remove the support plate.

Once the support plate is removed, you can lift the drive belt over and past the toothed drive pulley, then remove it from the drive ring.

Start by installing the belt around the drive pulley. Rotate the clutch eccentrics to maximize the gap between the machined pulley and the clutch eccentrics. Then install the belt around the belt gear.

Install the mounting plate on the clutch eccentrics and the gearbox shaft, ensuring it is fully seated. Then insert and tighten the two screws using the 3 mm Allen key.

Align the arrow inside the front cover with the arrow on the drive ring. Then press firmly all around the front cover to secure it firmly to the drive unit.

Yes, it is essential to adjust the clutch after replacing the drive belt. This step ensures the unit operates correctly and prevents the belt from slipping.

The clutch is correctly adjusted when the drive ring can rotate freely when the clutch is disengaged, and the drive belt does not slip when the clutch is engaged and the engine is running.

Engage the clutch. Use a 3 mm Allen key to loosen the clutch button screw by about 2 turns counterclockwise. Turn the clutch button 4 notches clockwise to tighten it, or 4 notches counterclockwise to loosen it. Use the Allen key to retighten the clutch button screw. Ensure the wheel still moves freely with the clutch disengaged. If not, reduce clutch tension by 2 notches counterclockwise and check again. Verify the drive operation with the clutch engaged.

If the wheel does not move freely with the clutch disengaged after the initial adjustment, you must reduce the clutch tension by turning the clutch knob 2 notches counterclockwise, then check the wheel movement again.
