we ahve rebuilt them before with different degrees of success if it is only where the seal runs you can use a two pot epoxy resin then machine them down to a smooth finish we have had great succes with that..if it is worn where the roller clamp you have only two choices one is split the rollers form where the small rectangle hole is up between the bolt hole this allows the rollers to clamp up tighter the other choice is new shafts which are $281 aud
