Video Transcript for Lippert Slide-Out Gear Pack Installation - 2019 Grand Design Reflection Fifth Wheel

Kevin Hey guys, Kevin here with etrailer. And today I'm gonna be showing you how to replace your worn out gear pack for your slide out on your 2019 Grand Design Reflection Fifth Wheel Trailer. If you're having issues with your slide out not really wanting to come all the way out or come back in. Maybe one side's kind of starting to come out more than the other, might be a good time to get down there and look at your gear packs. Your gear pack has a crown gear in the center of it which has teeth in it and that's what actually kind of helps move your slide out in and out. Those gears get chewed up too much then you're not gonna be able to have your slide out actually move forward or back.

Here's what our gear pack is gonna look like once it's installed. We have our two rollers which are gonna ride along our arm here, and our crown gear which is actually gonna bite into the teeth on our arm and force our slide out to move in and out. As far as installation goes swapping at your gear pack can be super simple. The only thing you may run into some issues with is just a seized up bracket, just because sometimes over all the years, all that usage, that bracket can kind of get gunked up and really wanna stick to the mounting brackets on our frame. So you may have a little bit of issue trying to break that off, but shouldn't be too bad.

One of the things with this is in the instruction manual they tell you to place your slide out about halfway out. I feel like that's a little bit too much. I'd say anywhere from like a third to a half would probably be better, just so you don't have as much tension coming out because as this bar comes out, it's leaning all that weight more towards the outside which is pushing down on our gear pack here. If we have a little bit more in I wouldn't have had as much tension on here it would've been easier to swap out. Now that we've gone over some of the features of our gear pack, let me show you how I installed it.

The first thing you're gonna need to do before picking out your gear pack is to actually measure the arm. Once we measure our arm we'll have three choices of gear packs to choose from. We're gonna have a two by two, a two and a half by two and a half, or our two by three and three by three gear pack. To measure that, we're just going to take our tape measure up and looks like our arm is two inches by two inches so we know that we need the two by two gear pack. Just to give you a little bit of a reference I have our two by two and then our two and a half by two and a half.

Now on our two by two, there are spaces for our roll pens but they do not come included. On our two and a half by two and a half and two by three and three by three gear pack we do come with these roll pens and these are important because that's how you can attach to your room bar, which will go between your gear pack on both sides of your slide out. I'm gonna start by disconnecting my room bar. I'm gonna set that aside because we're gonna put that back in once we replace our gear pack. Typically, your room bar can kind of collapse into itself. I just noticed cause I was having some issues getting it off. It's actually been welded. So our inner piece of our room bar and our outer piece are welded together. So this isn't gonna collapse at all. Which, not a problem. We can still get our gear pack out without having to collapse us in but it does help a little bit getting it off if that's not in your way. Now we can go ahead and we're just gonna break these bolts off here. Just get off my hand. All right, now we can start to pop our bolts out. We may need to use just a rubber mallet to get this out just cause this got a little bit of tension on it just from use over time and it's kind of gunked up a little bit so we'll grab our rubber mallet and get these out. Rubber mallet's not gonna fit back here I don't even have to use a steel hammer just wanna make sure that we're being careful we don't wanna damage anything. In our case, I am gonna need to also use a punch and just kind of hit the center of that bolt just to get it the rest of the way out cause it's just really sticking. Pull our bolts out. If you're having a lot of issues with the tension it is the room bar. Like I said, with ours being kinda welded in place really just have to sit there and fight the bolts out. You can take that room bar off and just easily slide it back go ahead and do that and make your life a whole lot easier. Get that bolt out the rest of the way. And then we can slide our gear pack out. If you look at your gear pack you can actually slide these brackets off and our rollers and then get to that crown gear. Our particular one here is a 15 tooth one but there are 18 teeth models. This is a replaceable part so if just your teeth are messed up and the rollers are fine, they're looking good no dents, no cuts in them you can go ahead and just replace that gear. Just match it up with what you already have or on some models you do need to kinda look because there are tech notes saying if it's within a certain year that you'll have to use the 18 tooth instead. All right, so now I'm gonna kinda line up my holes for my room bar. Get that slid in. When we look at our brackets here, it has a little bump out and that bump out's gonna sit inside of this well right here. I wanna make sure that we're sitting up against that and that this portion of our bracket is flat up against our mounting bracket up here. We're gonna do that for both sides. I'm just gonna try and slip the back bolt in first. Slips right in, and we can throw our front one in as well. Kinda lift up our whole assembly here. You need a little bit of persuasion to get this in. There we go. Just cause adding that room bar on there puts a little bit tension. Here we go. And now all we need to do is replace our nuts back on here and we'll just tighten those down. Okay, just double check they're even. Yep, all right. There isn't a torque setting for this so it's just getting it as tight as you can just with the wrench. And now we can go ahead. We actually slide my bar down just a little bit so I can get it matched up with our room bar here. All right. Now we can try getting our pull back through. It'll go up, and then you'll go just a tiny bit more. Like I said, typically you'll have one of those sheer pins in there on these and you won't have to really worry about it. Those sheer pins are designed to obviously just sheer away. That way if there is ever an issue you're not gonna destroy your whole assembly it'll just snap off of that room bar and not allow it to travel anymore. We can go ahead and take our wrench and tighten that down as well. Once you have all your bolts all nice and tight you can go ahead and run your slide out in and out just make sure it's working properly before you take off and go on that camping trip. Well, I think that about does it for today's replacement of our slide out gear pack here on our 2019 Grand Design Reflection Fifth Wheel Trailer. My name's Kevin, thanks for watching..

Average Customer Rating:  4.9 out of 5 stars   (24 Customer Reviews)

Replaces the gear pack of your Lippert through-frame slide-out with a 2-1/2" x 2-1/2" arm.

by:

The part worked as expected. Slide-out now works as it should. New end caps with new bushings raised the rail up and not binding any more.



by:

Bought 2 of the same part (one for each side) and they were both great. The buying experience was simple and fast. Would highly recommend ordering from here! Great easy worry free experience.



by:

slide-out gear pack looks well made,I changed out the 15tooth gear for my 18tooth gear. No problem, fit on the new shaft. Installed on my 06 Cougar with the new slide motor assembly (from etrailer) and slide works like new.



by:

After one year I'm still pleased with the way that slideout works, so pleased that I ordered the same replacement part to go on the kitchen slideout this summer.



by:

I needed this part quick. etrailer came through like always and overnighted it to me. It worked perfect to get my RV working so our planned trip is still a go. I have used etrailer for years and always a great experience.



by:

Our fifth wheel is 12 years old, I have replaced the gear rollers twice, these are by far the best ones I have had.



by:

Perfect fit. The slides work better than new. The video on etrailer.com gave the measurements so I was confident that they would fit.



by:

Worked very well.



by:

Much better than the original gear pack which had plastic rollers.



by:

The video describing the product stated that they were Zink coated. They did not appear that they are, and they are covered with a fair amount of rust.



by:

Every thing I ordered was spot on.

Shipped very fast and is very well made. Can't wait to install when the weather breaks.

The exact instructions are as follows: In the event a gear pack needs to be replaced, follow these steps: 1. Run slide-out room half way out. 2. Place a jack under the inner arm of the slide-out. 3.

    No, the Lippert Components 2.5 x 2.5 Heavy Duty RV Slide-Out Gear Pack part # LC123356 does not need to be synchronize for installation which I confirmed with Lippert for you. I have attached the exact instructions to replace the gear pack below. 1. Run slide-out room half way out. 2. Place a jack under the inner arm of the slide-out. 3.

  • Can You Use An 18 Toothed Gear On Instead Of A 15 Toothed Gear On Your Slide Out
    Thanks for checking in with this question, I have some information below: **Lippert Components 2.5 x 2.5 Heavy Duty RV Slide-Out Gear Pack - Steel Rollers # LC123356. I highly recommend going with the exact replacement and keeping the same gear tooth ratio. It may seem like an easy fix or a small matter but just adding one tooth may cause damage to your unit. The system is designed for 15 teeth and if you add more teeth or take some away it will cause the system to track wrong and cause...

  • How To Determine Which Replacement Gear Pack To Use on Lippert Slide Out
    I called and spoke to the technician at Lippert about the gear packs. If the arms that attach to your slide out are 2 x 2 you will need Gear Pack part # LC281331. If the arms that attach to the slide out at 2.5 x 2.5 you can certainly use Gear Pack with the heavy duty steel rollers part # LC123356. You want to go by the size of the arms attached to the slide out just to be clear. The steel rollers are an upgraded version of the Gear Pack for the 2.5 x 2.5. There is not a heavy duty version...

  • Correct Replacement 18 Tooth Gear for a 2010 Tiffin Allegro Motorhome
    You're correct, the Replacement Gear Pack for Lippert RV Slide-outs w/2-1/2" x 2-1/2" Arms # LC123356 uses a 15 tooth gear which is only going to work with Lippert slide outs made after October of 2013. With your motorhome being a 2010, you'd need to use the 18 tooth gear # LC122739 instead.

  • Can I Use 2.5 x 2.5 Gear Pack To Replace Gear Pack On 2 x 2 Slide Out System
    I understand wanting to use the steel rollers but you want to stick with the same size Gear pack roll pins for the 2 x 2 slide arm setup part # LC281331. The 2.5 x 2.5 gear pack part # LC123356 will not be compatible.

  • Troubleshooting Slide Out Crunching
    A slide out should - obviously - not be crunching and there are a myriad of potential issues that simply replacing the gear pack with one like # LC123356 would not be prudent. What it could be is that some how the slide out has become misaligned or there is some other type of internal issue that a simple replacement part would be unable to remedy. I very strongly recommend taking your 2015 Phaeton Tiffin to get serviced by an RV professional to diagnose the issue.

  • Can You Reuse Old Gears In A New Slide-Out Gear Pack
    Technically you could reuse your 18 tooth gear on the Lippert Components 2.5 x 2.5 Heavy Duty RV Slide-Out Gear Pack # LC123356, but if you're replacing the gear pack the gears themselves should probably also be changed. You can use the Replacement 18-Tooth Gear for Lippert RV Slide Out # LC122739 to swap the 15 tooth gears out for some 18's.

  • Should Both Trailer Slide-Out Gearpacks Be Replaced on 2006 Cedar Creek Silverback
    If one of your trailer slide's gearpack needs replacement due to damaged/missing gear teeth I do recommended replacing both. There is a chance that the alignment issue from the missing teeth on the one gearpack could have damaged or at least stressed the other one. Since you're going to have it apart anyway I'd spare myself the potential need to go back into it and just replace both gearpacks at the same time. Kit # LC140409 is for slide systems utilizing 2 x 3 and 3 x 3 tubing slide...

    Most likely the gear pack on the right side is worn and skipped a bit throwing off the alignment of your slide out. You should first start by checking for any kind of obstructions that could prevent the slide out from fully retracting and then start looking at the gear pack for any damage to the teeth. I've attached a video below where I remove and replace the gear pack so you can see exactly how to do this. I recommend running the slide out about 3/4 of the way out and using a floor...
