Rebuilding Drop Target Assemblies on Early Stern/Bally Solid State Games Posted on 2021-03-13 by admin Here is a series of three short videos covering the process of removing and refurbishing the drop target assembly on early Stern/Bally games. This is done on the Trident I’m working on restoring. After unscrewing the switch stack and the reset coil, you can remove the drop target assembly from the game. Then you an remove the individual drop target coils from the assembly by unscrewing four small screws. Note the inner plate behind the drop targets that has slid down – this is what the switch stacks screwed into, so you’ll want to connect them back to the assembly first, before putting the individual drop coil bank back in place. Since I wasn’t replacing the targets, I simply soaked the assembly in hot soapy water, then made sure to dry it completely before applying some dry spray lubricant. I also shortened the springs by just a tiny amount to make them work better. If you have replacement targets, they should be removed and replaced, which is done by removing the retaining clip and axle holding the assembly together at the bottom.
