More Schwintec problems

It could be the alignment is off between the slide and opening or between the racks themselves. This system is not very forgiving when they have some idiot installing them at the factory on a piecework basis, who cares more about how many he does a day as opposed to if they actually work.

Download every piece of info and manual at Lippert.

What do the teeth on the racks look like? It's easy to mistake aluminum dust from the gears grinding on the racks for lubricant when they are not aligned correctly.

Measure from bottom rack to top rack, those should be the same / parallel, and a specific dimension based on the configuration of the bearing blocks.

Measure length of the box itself top and bottom, and diagonally corner to corner for square, same with the opening. I don't have my info handy but there is a dimension the box needs to be smaller in relation to the opening, I think it's 4 1/2" shorter than opening width. 2 1/4" per side from memory, check the Lippert manuals. There is not much fudge factor here.

Are the columns mounted parallel with each other? That can be a tough measurement to check depending on the unit.

I have repaired / re aligned at least a dozen and about half the time have ended up having to remove the slide. It's a lot of trial and error. A few we have done were so far out of whack from the factory it's amazing they ever worked at all. You could watch the slide twist while extending it due to being out of alignment.

Another quick check is to disengage the motors and see how it feels moving the slide by hand. This takes two people on a large slide. I have also found that the larger the slide, the more problematic they usually are. Lots of brands cheaped out using these on large slides, and have since went back to a conventional through the frame or other type.

I'm not a fan of anything Lippert but a lot of the time Schwintek issues can be traced back to the OEM installation.
