A winter project, have one of the hide away doors on just a little off. Before I installed this spring, everything moved freely using a vacuum pump, bushings seemed snug but I did replace the rubber bumpers which stops the doors in the upper or lowered position. There doesn't appear to be a mechanical adjustment so I will probably change the vacuum lines due to age.
Has anyone had to adjust the movement of the doors? Shim the actuators? Replace the actuator?
