lippert schwintek slide system problem
We have a lippert schwintek slide on our bedroom slides. The small one was dragging and I had to assist in in retracting by pushing on it to get it to fully retract. I found a piece of gasket that ...

Schwintek is very dependent on the original install. If they have the racks and drive mechanisms out of alignment, as well as the opening in relation to the box off, it causes all sorts of issues, one being the timing going out of sync every time you operate it. If your capable read every manual and troubleshooting doc you can find at Lippert's website, and start taking measurements. They tend to change and move/remove that tech info a lot on their site, because they don't want you working on them. I wont go into every step but the first thing I would check is extend the slide fully and measure from top rack to bottom rack on each side, both near the sidewall and front of the slide, they should all be close to the same, as in parallel with each other. The lower rack is kind of hard to get screwed up as its an L and attaches to the bottom corner of the box, but if the upper rack is not parallel with the lower, thats not good. Then take a 2' carpenters square and put the 16" leg on the sidewall. The racks should all be close to the same alignment with the 2' leg of the square, not necessarily perfectly parallel with the square, but all the same and not off by much, say 1/8' max, they should be square with the H column which is mounted to the opening sides and is what holds the motor, drive rods, bearing blocks etc. These manufacturers are notorious for counting on the Schwintek assembly to totally support the slide itself with no rollers. Not so much of a big deal on a 4'X 4' wardrobe or headboard slide, but can be a huge issue on a large slide.
I've repaired / reinstalled quite a few, and some were so out of alignment from the original OEM install, it was a wonder they ever worked at all.
The Schwintek was never originally designed to be used on some of these 12' long full height slides you see it on now days IMO.
I once watched two Bozos during a tour of one of Keystones plants installing slides with Schwintek drives. The first thing they did was removed the factory bracing that keeps the racks in alignment and is supposed to be removed after the racks and H columns are mounted, and toss them in the trash bin. Then they blew the racks on the box by eye. They went on to the next on the line without ever using a tape from what I could tell. I also had a trailer I ordered come in with the racks so far out of alignment that when it was extended, one side lifted an entire inch as it came out.
