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..

This was an exact Lippert replacement for my slide. Everything lined up perfectly.

The replacement gear pack is doing just great after a year. Its one of two on a large front slideout.

  • Is the Lippert Components 2 x 3 and 3x3 Standard Slide-Out Gearpack Heavy Duty
    We have the standard gear pack for the 2 x 3 Lippert slide outs but we do not have a heavy duty option. Did you wear out your old gear pack quickly? Typically a heavier duty option than this isn't needed. The part # LC140409 is what you'd need. The word standard in the title of this does not refer to quality or durability and is more related to the standard application. This is a heavy duty option that would work well for you.

  • What Does 2x3 and 3x3 Refer to In Description of RV Slide-Out Gear Pack
    You are exactly correct, that is referring to the tubing size that makes up the arm assembly. The Gear Pack bolts to the arm assembly, so the housing needs to be the correct width in order to fit.

    The Lippert Components 2 x 3 and 3x3 Standard Slide-Out Gearpack part # LC140409 is one of the most common replacement gearpack for modern campers. To ensure it will fit check the tubing slide arms on your slide out and ensure they are 2x3 or 3x3 if they are this will be a direct replacement.

    Great question. When replacing a gear pack like Lippert 2 x 3 and 3x3 Standard Slide-Out Gearpack # LC140409. Follow these straight forward steps: 1. Run slide-out room half way out. 2.

  • 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...

For 2 x 2 inch tubing you will use # LC281331 for a replacement gear pack. There is also a 2-1/2 x 2-1/2 inch tubing option # LC123356 for the heavy duty...
