  • Need Suggestions on How to Close Gap Around Lower Bearing Blocks

    What would you do to seal up this area?

    Around both lower bearing blocks on my Schwintek slide there is a large gap that allows light, (hot or cold) outside air, and of course small winged creatures with stingers to enter the bedroom.

    For orientation, the Schwintek is the slide with the "rails" on the side. On my 315RLTS it's the bedroom slide. The DW held a flashlight outside near the slide's lower bearing block and I took pictures inside. Then I took a picture outside looking in.

    The bearing block is stationary--the slide moves, not the block. The bottom spur gear is driven by the torque shaft. (You can only see the V-Roller which is below the bearing block in the picture.) It appears there's a missing seal or it's not cut correctly? (The one in the outside picture is the outer wiper seal but it doesn't appear to fit around the slide as shown in the diagram below..)

    It's almost as if that lower seal (not the one I'm holding--the one up against the bottom of the slide's bottom) is too far inboard?

    Nothing can be attached to the slide--as previously stated it moves. A little befuddled at the moment on what to do.

    For those with Schwintek slides, (please) take a look at yours and post how the seals are configured in this area. If you have a gap like mine, I'd appreciate knowing that, too.

    If anyone has any ideas...please fire away.

    I can tell you from experience that steel wool will keep critters such as mice out of pocket corners but regarding the sealing from cold or hot air....I have no answer.

      Howard I have the same holes - I was trying to think of a way to add a bulb seal, or foam it closed using plastic wrap as a barrier to areas I did not want the foam to stick to. been too busy with the Blue box and panels. Its on my round to it list.

      I just had another thought .What about carving up a pool noodle to fit the space. You could use double face tap to hold it in place. Their closed cell foam. so wont trap moisture.

        A couple of issues I've found this morning.

        Issue #1:
        I found out why the lower Schwintek rail facing forward is allowing more light than the side facing aft. The lower inner wiper seal is completely torn off. I found it under the V roller. Only speculation is it somehow got caught in the roller mechanism and tore off when the slide was retracted. It's been this way for quite awhile, so no telling when it happened. There's no replacing that seal without removing the slide. (Not going to happen.)

        Unfortunately the outer wiper seal on that lower forward side is also torn, but it's still in one piece, so Super Glue should take care of that. (Super Glue instantly bonds the rubber seals--so be very careful if attempting to use the glue to "fix" a seal.)

        I also learned that the inner and outer wiper seals below the bearing block don't sit flush or seal well around the gear rack, either. Some light may pass by the seals regardless of their condition.

        I don't know if it's related, but the bulb seal at the base of the same side with the torn wiper seal had the bulb seal pinched into the lower assembly. I had to remove it and trim the destroyed end.

        Issue #2
        I don't know what this part is--it is not covered in any documentation I have for the Schwintek.

        On the inside of the trailer along the floor there's a wire guide(?) with a "V" facing upwards that extends to the side of the slide. It's bent down so far that light pours through.

        My trailer has the old style bulb seals (separate from the wiper seals), so I moved the bulb seal from inside that "V" to outside the "V" to compress / hold the "V" in place.

        That change definitely cut the amount of light entering to just that which sneaks past the wiper seal. (Yes, since I moved the bulb seal down there's now a gap where it meets the horizontal bulb seal at the top along the ceiling. I have to get new bulb seals and cut them to the length I want. Note that there's so much light still entering in the picture on the right because this is the side with the missing inner wiper seal.)

        Still working on a fix for the missing wiper seal issue. I think there's a solution...the DW and I worked on it all morning. Will post later after a run to Ace Hardware and more experimenting.

          I am wondering if the "V" item is a water catcher or drain type item to catch and drain any water that may enter on the rails or seals. Just thinking on what it could be or do.

            It be will on my list of questions for LCI and/or a GD tech at the rally.

            Had more "fun" this afternoon looking over the seals around the bottom of the Schwintek. Too tired to post my temp fix, but there's another problem that won't get fixed until the slide is pulled. I'll take a picture of the bottom seal tomorrow where I found a split.

            I'm starting to understand the appeal of a camper with no slides...

              I had an issue with mine just like that, I caught it early and was able to get it fixed under warranty. The seal got caught in the rollers on both sides and ripped them both. On mine the bulb seal is double side tape and the wiper seal fits into a channel. I ended up having all of them replaced. Do not think that helps with your issue but your issue seems to be common.

                howson - did you need any additional pictures of the slide? We are out camping for the remainder of the week, and can grab some additional pictures of our slide of you need. Although, I may not be able to post them right away, and will need to wait till we're home, since the file size will be too large from my phone. Anyways, let me me know and I can snap them, and post them at some point!
