slideout questions

I recently purchased the lippert slideout service assembly bracket for my kitchen slide. It came with no instructions for installation. Would anyone have a picture of the brackets installed on their Montana or advice on installing them?

We need to know your RV model number and if you're talking about a hydraulic slide or an electric slide. I'm unfamiliar with a "service assembly bracket". Can you post a photo of it to get us headed in the right direction?

His personal profile says it is a 2020 3121RL, so it is a hydraulic slide.

I would guess he is referring to a roller for the slide... my three hydraulic slides dont use rollers...

Lipperts nomenclature calls a lot of the rollers a "Service roller"

Randy,
Just got my brackets and they are not going to work w/o substantial modification(s). I just sent photos to Lippert for follow up. There is an issue with vertcal clearance and the holes that are supposed to fit over/around the nubs of the 2 wear guides are not properly spaced (they are about 1" centers vs my actual wear guides which are about 1-3/4" centers).

The concept is to jack your slide arm to remove the weight on the gear pack, pull the outside GP bolt and Insert it thru the assembly as you re-bolt the gear pack - then crank the heavy plate down to remove the "crown" from the top of the inner arm (which holds the gear pack).

Photos attached for those that want to see the part and issues. Note the assembly is sitting on the inner arm and is too tall to go back on top of the outer arm where it needs to be installed.

I have a 2020 3121RL. Here is a picture of the bracket. It is supposed to prevent the crowning of the slide out tube.

RipNC.
That’s the issue I was having. If mounted it pushes the wear tabs out. It is too tall but I can cut the excess off the bolts so that is not an issue.

I'll post here when I hear back from Lippert.

My wear guides are spaced almost where the bolts are welded to the heavy plate so no clue how they could fix the current assembly. Seems a different configuration might be required.

The following response from Lippert is contrary to the discussion I had with a customer service rep named Vance who was very knowledgeable on this issue and has actually done work on this slide issue. I will be calling in and NOT FOLLOWING THIS ADVICE:

"The portion of the outer tube with the wear tabs will need to be pounded down some so it is flat. Then the bracket will need to be placed on the outer tube with the plate pressing down on the wear tabs and metal. In some cases the portion of sub floor would need to be removed so the bracket can sit correctly. I would double check with your coach maker to see if the subfloor is two piece wood with foam core. If you have any questions please feel free to call our techs at 574-537-8900"

So the slide out tubes are not heavy enough to handle the loading of the slide thereby causing the tube to bend (crown)?

Just a question. We are getting ready to pick up our unit so I am just trying to understand.

Thanks

1Hwy,
Sort of. Yes it is too thin but also caused by adjustment issue - if the inner arm sits too high when the slide is closed it will not make good contact with the gear pack and skip teeth. The arm being to high also pushes up on the (too thin) out arm and causes it to crown and makes skipping more likely.

Randy,

Today's call suggested adding a plate with proper hole spacing over the wear guide nubs and then installing the service assembly. HOWEVER, field measuring the service assembly I realized that even with the bolts cut it isn't going to over the outer arm (much less after adding another 1/4" plate). The center of gear pack bolt to top of outer arm is 4" and max clearance in service assembly is less than that (even with the nuts on the wrong side of the bracket - should be inside the bracket - see photos:

PS - I've submitted these photos to Lippert and will again follow up. However, I think a welder could straigthen and weld a plate (with proper nub holes) and solve this issue, it's only $$$...

Found this photo on an SOB site, fixed by straightening and then welding 1/4" plate, this had 1 wear guide in center and plate had a hole drilled (where the nub sticks up) before the plate was welded.

So…. I guess we spent $140 unnecessarily. Lol. I appreciate all your time spent on this. I believe I’m going to fab a piece to weld on the top like your last picture.

I think you can return them. Lippert sent mine for free. I think I will have it welded too. Unless I can get it fixed at the rally...

I bought these slide pads https://smile.amazon.com/dp/B079CT1N...roduct_details and they worked well for our trip to Morryde for IS last week. The pair was so long I cut them in half, rounded the cut ends and removed some of the 1/2" pad and bent down the edges - we use one on each end of each slide and it has solved our skipping for the time being. Here is photo of the modified slides:

PS - slides are quieter than they've ever been! These keep the slide more level as it goes out - normally the inside edge will drop a bit as it starts out and the arm is pushing a bit upward allowing the skip. I've also done this Lippert fix (though originally for single wear guide - I did it on both). I've lost one washer on last week's trip, but I made spares.

Does anybody know if the tube steel inner tube is the same size/thickness on the 2020/2021 models as has ALWAYS been used by Lippert? Or did they change and start using a thinner walled tube that is subject to bending under compressive load as the slideout is being retracted? Has this been an issue for years and years?

Also - what causes a gear pack to bind - therefore placing the tube into high compressive load so that it bends/crowns?

Mike,
It doesn't really bind, but as the slide comes in it first angles upward over the glide strip, as it reaches midway it starts to angle downward until the bottom pulls in tight at which point it is fairly level. The point at which it angles down will lever the inner arm against the wear guides at the top of the outer arm which contribute to the crown problem. Depending on the vertical adjustment of the outer wall the inner arm may not be down on top of the gear pack when the slide is retracted, if so it can be pushing up against the wear guides (I learned this on today's call) and should be slowly adjusted so it doesn't push up there when the slide is closed. Further, if the arm is pushing up on the outer arm and wear guides when closed it will not be in firm contact with the gear pack which creates room for it to skip teeth. The idea is that the rack is down on the gear pack when closed but not pushing the slide up off of the glide strip.

After I hear back from Lippert (doubt they have another solution since this sefvice assembly doesn't fit), I plan to close my slide and see how it looks and adjust if required. I'll post photos of before and after to this thread.

I do think the outer arm could have been beefier or had a plate tacked to it like the screenshot in my post #13.

There are videos and pdf files on slide adjustments, but most important is to make very small adjustments.

PS - I can gauge the outer arm thickness with a caliper, but I have nothing to compare it to. I suspect that the gauge is the same but the slide is heavier (primarily the residential fridge?).

Just curious - is the inner tube designed with camber (crown)?
Or is it designed to be stiff and straight as an arrow? It sounds like it is meant to be a straight tube and it pivots over the wear guides like a see-saw?
Also - is the outer arm/tube really just a fixed sleeve?
…and - what are the trim tabs made of? Plastic or metal? Those are the things Lippert shows to insert the cut washer into.

Sorry to be asking so many basic questions. Just trying to get my arms around the concept so I will better understand how to watch my slides.
