Do any of you guys know how to replace one of the rollers/bolt combo on the drive sprocket of a 257? My new machine is missing one and you have to install the bolt from the inside closest to the machine facing out and I don't see how it can be done without dismantling the whole sprocket/drive. I don't know how one came loose and dislodged itself, because there is no room at all. Just checking hoping someone who has one of these has been through this exercise.
