Re: Re-Setting Torsion Ride

There is no "bar" as such to limit anything. The entire limiting action is done by electrical switches.

In 55, switches are external and both are located in a single box on the compensator assy next to the solenoids. When a transverse bar is moved by the compensator, as a result of that movement it swings slightly at the compensator end. That swing movement is enough for the bar to hit an arm connected to the limit switch at a certain point. That action stops the motor. As was mentioned earlier, if the bracket gets bent then one direction does not work early enough and the other works too early. One that doesn't work in time can do damage and the one that works too early limits the compensation range.

An electrical problem such as a shorted solenoid or some of the wiring shorted to ground completely bypasses the limit switches which can result in the overtravel. If the fuse doesn't blow in time the motor keeps going and tries to rotate the transverse bars past the center. That results in the sheared off gear and bent bars some have mentioned..

As to the max travel, that is somewhat limited by the geometry of the system. You have the rear stabilizer assy which has limited range as well as the amount of twist that can be generated in the compensator bar. The amount of load at one end or the other also affects the range. If, for example the rear is heavily loaded the system can't raise enough. If the front is heavily loaded, the system will try to pull the rear down to match. Either situation might result in limited range -- for example, using your numbers it might be able to move 7" in one direction but only 1" in the other.
