My Linhof MT 2000 has a problem recently. The small pin of the little arm could not contact a little wheel for moving the front frame up and down well. The teeth of the wheel are fine for the camera is relatively new. The little arm can not stay straight for it has no contact with the little wheel. I wonder if I can push down or tighten the pin of the arm a little bit, it will contact the teeth of the wheel well. Then the rise and fall functions of the front will be fine. Is it easy to fix it?
Thank you very much for your help,
