Good morning everyone, I started replacing the center pins; I noticed that the styli move a little bit laterally, but by inserting a pin with a diameter that is too large, the stylus and also the hitchpin lock up. Consequently, can you tell me how much lateral movement the stylus needs? Many thanks to all.

nobody!!!!! Straight regulators are necessary. This is one of the most difficult jobs. The friction must be 3-4 grams. No oscillation. The pins must be oversized by a minimum of 0.25 mm
