Slide problems

OK...had a buddy that's son was getting married....loaned my trailer to him because he had a bunch of family coming into town. Trailer is a forest river 29SKBS.

Next time we took it camping the rear bunk slide would not work. I found that the switch was bad, and the fuse was blown. Swapped both and it blew the fuse again. To try to keep the story short, figured out that the slide motor was bad. I have no idea what caused the failure.

It had a Thomson Saginaw Performance pack 7828696 18-1 drive assembly. From reading online, I guess these are known to fail.

Here it is with the angle drive still attached:



Found an AP 014-125802 18-1 drive assembly online, and was told it was a direct swap. While swapping it, I found the mounting bolts that hold the angle drive and motor onto the wall loose. I tried to tighten them and they just spun. Replaced them all with a size bigger diameter (1/4 to 5/16). When I tried to operated it, I realize it was not that the bolt that stripped, but something in the wall has given way where the bolts go in (new bolts did not grab any better than the old bolts). The drive motor assemble/angle drive has since came loose from the wall.

So...was looking for idea for a fix. Best thing I can think of is getting a metal angle iron that goes the 4.5 inches up the wall and as far as possible out into the floor, and bolt it to the floor, and hope the floor can handle the torque...

The assemble could be moved left or right, or to the other side of the slide rack if I wanted to...but not sure the wall could handle the torque any better in those locations either.

  • It looks like your idea of some steel angle mounted to the floor would do it. And then bolt the motor to the vertical part of the angle.

    There seems to be plenty of play in where you mount the motor.

    Drill all the holes in the angle before installing it.

    Good luck.
  • Thanks Ron....I was thinking of something that also included mounting to the floor. I am just not sure what is in the wall there, and fear they screwed the original motor to a styrofoam sandwich wall.

    Not sure how I could find studs (if there are any) in that wall. I think a stud finder would pick up all the staples holding the slide flange gasket right above the motor.

    Local dealer did call forest river, who said the original manufacturer of the drive assembly is no more, and a new Company was making the motor, but they were bought out by Lippert...looks like I do have the replacement motor they are using now (feared a wrong motor caused some of this).

  • If the motor could be spaced, say 1/2" from the wall, it might be possible to use a piece of high quality 1/2 ply (maybe a 7 ply Baltic Birch) as tall and as wide as the existing wall where the bolts go in, using several screws/bolts to attach the ply to the wall.

    Or perhaps just a flat piece of steel, maybe 1/8" thick and a foot or two long bolted to the wall in a manner similar to the ply above. It looks like the problem will be to get something on the wall that is stable, won't move, and also something that you can bolt into or thru to get solid structure.
