Update on Lippert slide mechanisms

I should explain what the trouble I had was. One of the slide motors was not properly seated in place. The bottom of the motor has 4 roll pins protruding from it that go into holes in the drive mechanism frame. Those pins prevent the motor body from rotating when it runs. When the motor is properly in place, a screw is run through a cover plate and sticks into an oval hole at the top of the motor that also serves as a cooling vent. In my case, one motor's roll pins were not seated in the drive mechanism frame. This left the motor sitting about 3/4" higher than it should have been. Now, instead of securing the motor from raising up, the screw was the thing keeping the motor from rotating. As the hole was oval, the motor was free to rotate a little but luckily I found the problem before the screw did any real damage to the motor. I found out what was wrong after about a year and a half when one side made a loud pop and the slide jammed. What had happened was all this time the coupling between the motor and the slide mechanism shaft had just the slightest of engagement but was still doing it's job. After a year and a half of wear, the minimal engagement allowed the "teeth" in the coupling to strip. They only had had about 1/16 inch of engagement so the coupling was still usable once I saw the problem with the motor not being seated. Once I engaged the roll pins, the motor went down 3/4" and the coupling was OK with that. I redrilled the securing screw hole 3/4" lower and all was well although the oval hole in the motor shell was pretty beat up from the twisting back and forth. With the pins properly engaged, now the screw does it's intended purpose of just preventing the motor from lifting up while the pins prevent any rotation.
