Schwintek slide repair

After three full wall slide repairs (all paid for by WGO) and a fourth repair just completed at the WGO factory, I now have a very good understanding of the causes of the problem.

We stopped at Forest City to have our slide inspected and repaired if needed. I was not comfortable with the last repair which was to upgrade to the new Powergear system which was completed a few months ago. The tech found many items incorrectly done or missed completely by the dealer tech. All were fixed.

The really interesting thing was the tech telling me about "over center tip", which is when the weight of the L shaped counter causes the slide to dip very close to the aisle floor this causes the slide rails to bind with the top and bottom moving in different angles. The top of the slide hits the side of the mh first, and the bottom is then pulled into place, placing great strain on the slide rails because the top gear wants to stop and the bottom must pull the slide in.

I had always wondered why our slide would suddenly dip down about a foot before completing the retraction process. The overcenter tip is the cause. The fix is two new rollers installed under the counter which prevent overcenter tip.

Our slide now runs smoothly and at a constant angle and the slide mechanism sounds just like the smaller bedroom unit and the sound never changes throughout the retraction process. Placing the rail brackets corrrectly likely also helped as did several other fixes.

I would strongly recommend slide repairs only be done at the WGO factory where that is what this tech does all day, every day. Dealer techs get a short training course and only see a few of these repairs and cannot be as proficient at it. If your slide still "dips" near the end of the retraction it probably needs some rollers added. If your mechanic does not know what "overcenter tip" is, find another mechanic.

I suspect many original Schwintek systems never had a prayer of lasting because of the tremendous strain put on them due to a poorly designed system. Now with more rollers added and a far more robust Powergear system properly installed, I look forward to good service for a long time.

BTW, he did say no lubing needed and be sure to have jacks down and level and engine running before extending slides.

Hope this helps some.

    The Scwhintek system is dependent on having slides perfectly built, perfectly aligned, and the system itself installed perfectly and in alignment. Good luck hitting that trifecta with any of these RV manufacturers. But if you do you'll most likely never have a problem unless its on a large deep slide.

    Lippert acquired Power Gear in 2014 They'll cheapen that system the same as they did with Schwintek if it hasn't already been done.


    WHERE do you get your information? I am not a big fan of LCI but, the original Schwintek system before LCI bought the patent from the Inventor, had defects. Schwintek DID improve the system and now it is a very reliable system. BUT, the OEM's are at fault for this posters problem and the numerous problems over the years with Schwintek. The Schwintek system just moves the room in and out. That is ALL it does. ALL other parts of the slide room---rollers - wall cut out and frame build for strength and a SQUARE room are the OEM's fault. As well as this Winne build. Winne designed the system and just used Schwintek to move the room in and out. The fact they went to the different design Powergear for the posters problem shows Winne had a engineering design problem and they came up with the fix. Doug


    I agree it was originally a WGO design problem by not putting enough rollers to prevent overcenter sag. It has been multiplied by dealers trying to get in on all the warranty work fixing the slides and shoddy factory construction and quality control. The dealer techs did not receive adequate training and do not do enough to keep up proficiency. This leads to rapid failures on the repaired unit. LCI bought Powergear and the new design the Powergear team worked out seems to work well when combined with adequate rollers installed and proper installation of parts and squaring up the slide in the opening correctly.


    It had NOTHING to do with the Dealer tech and his Knowledge or proficiency. WE(Dealers) do NOT do things like this on our own. We MUST contac the OEM,(especially if multiple repairs have been made for
    the same problem), and THEY (Winne Tech support) tells us what to do. They do NOT just send out parts and pay labor willy/nilly. So, In your case it was Winne, not your Dealer Tech that did not get the problem fixed. Winne should have told the Dealer tech what the problem REALLY was and advised that it is best to do a factory repair. That is why we must contac them on almost all warranty repairs. They may have a update to a problem and will advise us of that update. Odds are the Dealer Tech was attempting to do the repair BEFORE Winne finally acknowledged that there was a design problem. Rarely do OEM's send out TSB's on Design defects. They expect the Dealer to call and IF they have an update they advise us at that time. Doug


    As I stated it was a WGO design defect. The training was also deficient I am sure. But the installation of the retrofit kit was also poor. My initial concern was wiring openly exposed. I was sure that was not correct and the WGO tech confirmed the installer did not clip the wiring harness in provided clips. Nor were provided washers installed to keep the rails from rattling. The rail brackets were also installed incorrectly. Teeth markers were visible above the rail where something had rubbed where it should not have. The provided vinyl strips supposed to be mounted behind the rails to prevent makers on the slide wall were not installed. These and a few other items can only be laid at the feet of the dealer.

    I completely agree however it was a very poor design and training program and probably a reluctance to provide rollers and instructions on the need for them that caused and made the problem much worse than it had to be. As a former mechanic myself I understand being asked to do the impossible with inadequate training.

    No lubrication? Makes me wonder if this video put out by Lippert on how to lube it is no longer valid: https://www.youtube.com/watch?v=8KbVRFMo1Rg

    Engine running before extending slides? My Thor product has an interlock that prohibits me from doing that.

    I am glad that yours is working better now. It is amazing how much contradictory information is out there about these slides. I hope that the foot dip is an overstatement. I can't imagine it having that much play without breaking something. My slides to tip a little when the CG of the slide passes over the rollers. They lean out when the slide is out and in when the slide is in but maybe 1/4 of an inch is all. The big problem with mine was that the rack was not shimmed properly at the factory and only had about 25% tooth engagement so the teeth wore out quickly. After several attemps at a field repair I had to drive it back to the factory to get it done right. I just don't know why it was not done right the first time. At least Thor did compensate me for some of my driving expense and were very helpful while I was there.


    No lubing needed on the new Powergear system. The biggest thing to lube on the old schwintek as shown in the YouTube video was the coupler which is now inaccessible. The other part was the gibb which has been redesigned. I did look on the Lippert site and no longer see any how to lube videos for the new system.

    Sounds like you had a good factory experience as well.


    Winnebago is still advising lubrication with CRC on the system I have in my 2014 Vista (not Powergear), and specifically pointed me to the LCI video which is still on Youtube as a reference for doing the lubricating. I spoke with Steve at WGO just yesterday about this, as my main slide is getting extremely noisy when encountering dips and bumps in the road. He assures me that this will fix my issue. Other than the noise, the slides have given us no issues in 2 1/2 years of use, so I hope he is right.

  • Good info and thanks for those tips.
    We have a 8' wide by about 12" deep slide that has tracks top and bottom. It has three rollers under it. (Its basically a closet)
    So far it works perfectly but it's only a few weeks old.
    Hopefully it has all the latest technology.
