    • As you can see on the picture there is a lot of dirt in the winding of item 20. Also there were some sand particles. These damaged the windings so that I had to sand it. Be sure to clean it in detail afterwards and do not apply any grease or oil because it would increase the rotating force. That will impact the autofocus mechanism badly.

  24. Tokina AT-X Pro 80-200mm Focus repair, additional/optional step: 步骤 24 中的图像 1,1
    • After you cleaned the focus ring, check whether item 20 rotates smoothly. If not you could clean it, too. But that means a lot of additional work because there are nearly 100 bearing balls.

    • item 21 is fixed with loctite to item 18. Use a cutter knife or similar to cut it.

    • grab item 21 at the two notches and rotate it counterclockwise to remove it.

    • Now item 20 is also loosened. Before you remove it be sure that the bearing balls that will fall out will not fall from your desk.
