Another way to repair a Schwintek slide

Joe, I am afraid that you will have problems in the future. The motor sits on an upper bearing block, which you can see in your picture, inside that is a coupler, a shoe, a spur gear which engages the upper track and a gib which attaches to a torque shaft which runs down to the bottom assembly whose gear engages the bottom track. The entire assembly needs to be plumb. By your picture something is out of alignment. It is possible that your motor is not engaging the tab at the top. Look at the very top of the motor in your picture and you can see an opening with what looks like a rotor inside. There are several of those holes around the motor. Just to the left of that hole you can make out a tab in the vertical column. That tab should, I believe, go into one of the holes to keep the motor from rotating. If it is not engaging that may **** the motor. If the problem is further down it is only a matter of time until it fails.
